Page 6: Warnings And Cautions
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: Technical Specification
Product Compatibility SPDT microwave relays via interface The 4x-780B range has been introduced as an update to the cables existing 40-780A family. These remain orderable but the new 4x-780B is recommended as it provides additional options such as the PXIe control interface. The RF performance of the 4x-780B is identical to the 40-780A. - Page 8 NC 3 NC 4 heavily used contacts are swapped with lightly used contacts to prolong Microwave SPDT Switch (Part No. 4x-780B) the working life of the relay(s). in Dual, Triple and Quad Relay Formats Remotely Mounted Microwave Relay Versions 4x-780A...

Page 18: Technical Description
Section 2 - Technical Description Functional Description A functional block diagram is provided in Figure 2.1. The module is powered by +5V and +12V (PXI) or +3.3V and +12V (PXIe) supplies via PCI Bus connectors mounted on the mother board. The interface to the user test equipment is via the microwave relay’s SMA, N-type or 1.6/5.6 connectors. -
Page 19: 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 20: 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. -

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 support@pickeringtest.com... -
Page 33: 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. -
