Unused slots in the PXI/PXIe/LXI chassis are populated with blanking plates to prevent access to user I/O signals that may be present. Blanking panels are available to order from Pickering in a variety of slot widths. If the product is not used in this manner for example by using an extender card then additional care must be taken to avoid contact with exposed signals. - Page 7 Warnings & Cautions CAUTION - Product Documentation Symbol Suitably qualified & trained users should ensure that the accompanying documentation is fully read and understood before attempting to install or operate the product. Safety Instructions Safety Instructions All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O signals (refer to the Maintenance Section).

Page 13: Technical Description
Section 2 - Technical Description Functional Description A functional block diagram is provided in Figure 2.1. The RF Switch Module is powered by +3.3V and +5V (PXI) or +3.3V and +12V (PXIe) supplies via the backplane connectors. The interface to the user test equipment is via the front panel mounted coaxial connectors which can be - depending upon the model number - 26-pin multiway or individual SMB coaxial connectors. -
Page 14: Installation
Modular products require installation in a suitable PXI/PXIe/LXI chassis. The module is designed for indoor use only. Pre-operation Checks (Unpacking) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident. -
Page 15: Hardware Installation
If you are not a LabVIEW user you should choose the “full” version, and once that has been installed run the LabVIEW Runtime Engine installer via the shortcut on the Programs>>Pickering menu. In the absence of LabVIEW the Runtime Engine is required to support the Pickering Test Panels application. -
Page 16: Testing Operation
Figure 3.2 - General Soft Front Panel Icon A selector panel will appear, listing all installed Pickering PCI, PXI/PXIe or LXI switch cards and resistor cards. Click on the card you wish to control, and a graphical control panel is presented allowing operation of the card. Panels can be opened simultaneously for all the installed cards. - Page 17 Section 4 - Programming Programming options for Pickering Interfaces PXI/PXIe Modules For information on the installation and use of drivers and the programming of Pickering’s products in various software environments, please refer to the Software User Manual.

Once the drivers are installed the manual “Sys40Prg.pdf” and driver help files which fully describes these functions can be found in the Pickering folder(s) or the Pickering entries on your Start Menu. The card must be opened before use and closed after using the following function calls: Direct I/O Driver - Open with PIL_OpenCards or PIL_OpenSpecifiedCard and close with PIL_CloseCards or PIL_CloseSpecifiedCards respectively. - Page 21 Section 4 - Programming Using Pickering Drivers In LabVIEW Most Pickering drivers include a LabVIEW wrapper to permit full operation of the Pickering product from the LabVIEW environment. These wrappers are normally installed to the current LabVIEW folder system during installation of the Pickering driver.

PCI configuration, highlighting any potential configuration problems. Specific details of all installed Pickering switch cards are included. All the installed Pickering switch cards should be listed in the “Pilpxi information” section - if one or more cards is missing it may be possible to determine the reason by referring to the PCI configuration dump contained in the report, but interpretation of this information is far from straightforward, and the best course is to contact Pickering support: support@pickeringtest.com, if possible including a copy of the diagnostic... -
Page 27: Maintenance Information
For PXI modules which are supported in one of Pickering Interfaces’ Modular LXI Chassis (such as the 60-102B and 60-103B) no module software update is required. If the module was introduced after the LXI chassis was manufactured the module may not be recognized, in this case the chassis firmware may need upgrading. - Page 28 Section 7 - Maintenance Information Table 7.1 - Relay Look-up Table For 4x-755A-9xx RF Switch Module Relays Energised Switch Bank Signal Path 4x-755A-902/922 4x-755A-903/923 4x-755A-912/932 4x-755A-913/933 COM1 to CH1 None None None None COM1 to CH2 RL12 RL12 RL12 RL12 COM1 to CH3 RL11 RL11...
