&lt;/style&gt;&lt;br/&gt;
&lt;ins class=&quot;insert&quot;&gt;Calibrating Modules with Souriau Connector&lt;br/&gt;
Modules such as 40-755 use a RF connector shell that can that accepts coaxial inserts. This type of arrangement is popular in some industries because it allows a high density of RF connections to be made to a switching system. Connectors of this type are available from a variety of suppliers with very similar characteristics, including Souriau and Positronics. The 40-755 for example uses the Souriau connector.&lt;br/&gt;
These connectors are however not without their compromises. By their nature they are small, and have to use a crimp termination system on a flexible coaxial cable and this does have consequences for their RF performance. The manufacturers data suggest the performance of the connector alone degrades significantly above 500MHz.&lt;br/&gt;
This does create an issue when products using this connector are tested. The connector is a significant source of VSWR at higher frequencies and there is a danger that users in characterizing the modules mistakenly try to correct for the connector.&lt;br/&gt;
The standard practice is to characterize an RF switch at the switch interface (in this case the connector). Typically a cable is made up from the VNA to the switch interface and a back to back RF connection inserted to calibrate for insertion loss and a precision termination for return loss. This is not possible with these connectors, indeed doing so will typically produce highly optimistic measurements of the switch performance since the VNA will attempt to calibrate out part or all of the connector mismatch. There is no such thing as a calibration kit for this type of connector.&lt;br/&gt;
The method used by Pickering Interfaces is much more representative. Two sets of cables are made up to test the switch, each using the same cable type and each being of the same length. One set of cables connects from the VNA to SMA terminations, the other set connects from the VNA to Souriau connectors. The VNA is calibrated using the SMA cables but measurements are performed using the Souriau connectors. Since the SMA terminated cables have much better performance than the Souriau terminated cables the net measurement essentially included the impairments introduced by the Souriau connectors at the input and the output of the switch module but does not include the impairment of the cables in accordance with normal measurement practice.&lt;br/&gt;
There is one other characteristic of note in the use of this type of connector. Most RF switching systems ground the connector shell at a bulkhead (in the case of the 40-755 this would be the PXI module front panel). Multipole connectors of this type however do not. This does mean that the outer of the connector carries through to the RF switch without being grounded on the front panel. RF and EMC engineers would often consider this undesirable as it can lead to noise and resonant structures. The 40-755 has been designed to avoid these, but the version using the multipole connector is characterized to 500MHz rather than the 2GHz of the SMB version. Differences between the different manufacturers of multipole connectors are minor - at Pickering Interfaces we tested all versions and none had more than minor differences in performance and those differences were well within expected build variation expectations.&lt;br/&gt;
The switch design for both the Souriau and SMB versions is identical in the case of the 40-755.&lt;br/&gt;

&lt;del class=&quot;delete&quot;&gt;Switching&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;(September 2009)Switching&lt;/ins&gt; systems are&lt;br/&gt;
Users consider the switching system to be perhaps one of the most likely parts of the system to fail, with some justification but not because the switching system itself is unreliable. In providing this connectivity function though the switching system is placed in a vulnerable position.&lt;br/&gt;
It is true that switching based on mechanical devices has a limited life, but the life of modern relays is very high. Typical EMR’s often have life times quoted of the order of 100 million operations under light load conditions, instrument grade reed relays have lifetimes in excess of 1 billion operations. The key factor that effects in test systems is the load characteristics and the conditions under which the relays are operated. Whatever the type of mechanical device as soon as the relay has to close or open signal connections that have significant voltage or currents present the operation of the relay becomes a “hot switch” event – at the point the contacts close or open they are carrying a signal that generates an arc inside the relay which erodes the precious metal contact materials. Relay life is strongly influenced by the load present during these hot switch events, a variation of three orders of magnitude (1000) is a common change in life time between a light load and a full load. Designers try to avoid hot switching, but the reality is that some tests require hot switching of the signals to keep test times low, avoid having to restart systems between tests or to simulate conditions such as intermittent faults. Hot switching is a compromise that designers have to manage in their test systems.&lt;br/&gt;

&lt;/style&gt;&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt;If you do need some PXIe slots choose a chassis which has hybrid PXI slots so either type can be fitted and avoid chassis with PXIe only slots, it will maximize your chances of efficiently using the chassis. Make sure the chassis has an appropriate number of PCIe lanes to the critical slots and chose the embedded system controller or remote interface carefully to ensure it has adequate bandwidth to support the required operating speeds&lt;br/&gt;
Pickering Interfaces has no plans to introduce PXI Express modules since our products do not require the increased BW of PXI Express. It would have no impact on system speed and adversely impact module cost and particularly the off the shelf availability of replacement relays since the interface does not support the 5V power supply.&lt;br/&gt;

Using PXI &lt;del class=&quot;delete&quot;&gt;express&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;Express&lt;/ins&gt; does not&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; with backplane &lt;del class=&quot;delete&quot;&gt;speed.&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;speed, but speed advantages can be seen on modules that receive or transmit large amounts of data.&lt;/ins&gt;&lt;br/&gt;
The PXI Express mechanical and electrical interface is different to PXI. In order to make best use of the fast PCI Express lanes the chassis will typically contain a mix of PXI and PXI Express slots. So a chassis may detail a number of slot types for the peripherals as well as having a Star Trigger system that is also not compatible to the PXI Star Trigger. Typically the peripheral slots will be defined as:&lt;br/&gt;
PXI Express slots. These will ONLY accept PXI Express modules, of which only a relatively few types are available.&lt;br/&gt;
&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; sets of&lt;del class=&quot;delete&quot;&gt; connectors.

The vast majority of peripherals are PXI rather than PXI Express. The few vendors that are investing in PXI Express modules generally introduce both PXI and PXIe versions.&lt;br/&gt;
Summary&lt;br/&gt;
In general Pickering advise the following:&lt;br/&gt;
&lt;del class=&quot;delete&quot;&gt;Only use&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;Use&lt;/ins&gt; PXI Express&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; such as &lt;del class=&quot;delete&quot;&gt;video&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;video.If your application is mainly switching avoid using PXI Express, you are unlikely to fill the PXI Express slots and switching products do not benefit from the higher backplane speeds of PXIe. Relay speeds are not changed by having a high speed backplane.&lt;/ins&gt;&lt;br/&gt;
Do not&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; operating system. &lt;del class=&quot;delete&quot;&gt;Even on&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;On most&lt;/ins&gt; PXI&lt;ins class=&quot;insert&quot;&gt; systems&lt;/ins&gt; the processor &lt;del class=&quot;delete&quot;&gt;speed&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;capability&lt;/ins&gt; has a&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; execution times&lt;del class=&quot;delete&quot;&gt;&lt;br/&gt;
If you have to use PXI Express pay attention to the chassis selection - make sure you enough PXI slots (Hybrid or Legacy) because in most cases you cannot find all the modules you need in PXI Express.&lt;/del&gt;&lt;br/&gt;
Remember the breadth of product and the number of vendors supporting PXI Express is much narrower than PXI. PXI Express is also usually more expensive, partly because of the the lack of competition&lt;br/&gt;
If&lt;del class=&quot;delete&quot;&gt; your application is mainly switching avoid using PXI Express, you are unlikely to fill the PXI Express slots and switching products do not benefit form the higher backplane speeds of PXIe. Relay speeds are not changed by having a high speed backplane.&lt;br/&gt;
If&lt;/del&gt; you do&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; PXIe slots &lt;del class=&quot;delete&quot;&gt;use&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;choose&lt;/ins&gt; a chassis which has&lt;del class=&quot;delete&quot;&gt; both PXIe and&lt;/del&gt; hybrid&lt;del class=&quot;delete&quot;&gt; or&lt;/del&gt; PXI&lt;ins class=&quot;insert&quot;&gt; slots so either type can be fitted and avoid chassis with PXIe only&lt;/ins&gt; slots, it&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; efficiently using&lt;ins class=&quot;insert&quot;&gt; the chassis. Make sure&lt;/ins&gt; the chassis&lt;ins class=&quot;insert&quot;&gt; has an appropriate number of PCIe lanes to the critical slots and chose the embedded system controller or remote interface carefully to ensure it has adequate bandwidth to support the required operating speeds&lt;/ins&gt;&lt;br/&gt;

&lt;/style&gt;&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt;Understanding the BRIC&lt;br/&gt;
There is a demand for matrices in PXI based test systems where the matrix does not fit in a single slot module. Matrices can be expanded to make up larger configurations but the methods used are time consuming for the user to configure, often have performance implications and add costs. To address these applications Pickering Interfaces created the BRIC family of matrices.&lt;br/&gt;
&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; the BRIC &lt;del class=&quot;delete&quot;&gt;and&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;in 2002 a&lt;/ins&gt; new family&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; compaitble BRIC&#039;s &lt;del class=&quot;delete&quot;&gt;has been&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;was&lt;/ins&gt; introduced&lt;ins class=&quot;insert&quot;&gt; in 2009&lt;/ins&gt; which includes&lt;br/&gt;

&lt;/style&gt;&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt;As with Ethernet connections, the 40-736 also permits the easy connection of a test system to one of multiple devices with an AFDX port. As the switch is physically managed it is simple to establish which of the devices the test system is connected to - important when several identical devices are to be tested concurrently.&lt;br/&gt;
USB2 Switching&lt;br/&gt;
&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; USB connector&lt;ins class=&quot;insert&quot;&gt; interface or a higher density D Type&lt;/ins&gt; interface that&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; drops than &lt;del class=&quot;delete&quot;&gt;40-737.&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;40-736.&lt;/ins&gt;&lt;br/&gt;
In the case of USB2 the standard is particularly sensitive to to the cable length, transmission line reflections and voltage drops in the power connection for USB powered devices. It is particularly important that USB2 connections are kept as short as possible.&lt;br/&gt;
Switching Solutions&lt;br/&gt;
&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt;The 40-736 can be used for switching other serial interfaces requiring differential pairs, such as RS232 and its derivatives and POTS (Plain Old Telephone Signals).&lt;br/&gt;
For USB switching Pickering Interfaces recommends the 40-737.&lt;br/&gt;
&lt;del class=&quot;delete&quot;&gt;For more information on the 40-736 please follow this link http://www.pickeringtest.com/pdf/40-736D.pdf&lt;/del&gt;&lt;br/&gt;

Selecting a Resistor Module&lt;br/&gt;
Pickering Interfaces offer variety resistor modules with different features which make them attractive for different applications. As with most products resistor modules are designed with a number of constraints:&lt;br/&gt;
&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt;The following is a summary of the range from Pickering, the text should help you chose the best model for your application:&lt;br/&gt;
40-260&lt;br/&gt;
&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; separate connector. &lt;del class=&quot;delete&quot;&gt;http://www.pickeringtest.com/pdf/40-260D.pdf&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;&lt;/ins&gt;&lt;br/&gt;

40-265&lt;br/&gt;
Designed specifically for strain gauge simulation this module includes a bridge circuit and excitation system to allow it to emulate a strain gauge. The resistance control range is very small and has very fine control, permitting it emulate small strain levels. It supports a calibration port.&lt;br/&gt;

&lt;/style&gt;&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt;Pickering can supply a number of different types of connection solutions:&lt;br/&gt;
Connectors. Simple mating connectors that can provide a method for integrators to wire to a part that mates with the front panel connector of the selected device. These are ideal for systems where low purchase cost is required and labor is available to undertake the wiring operation. Some connectors are provided with back shells to protect the connecting wires. Pickering can also provide prototyping PCB mating connectors to add you in your system development.&lt;br/&gt;
&lt;div class=&quot;blockHeader&quot;&gt;...&lt;/div&gt; example, 8 &lt;del class=&quot;delete&quot;&gt;wayd&lt;/del&gt;&lt;ins class=&quot;insert&quot;&gt;way&lt;/ins&gt; Power D&lt;br/&gt;
Cable Assemblies. A range of cable assemblies with a mating connector on either one end or both ends. Cables can also be made available to convert between one connector style and another – for example converting between a high density connector suitable for use on the front of PXI or PCI modules and 50 way Ribbon Cable connectors.&lt;br/&gt;
