    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 Position B: 1 to 3, 2 to 4 The 4x-782B gives you the highest RF and microwave Microwave Transfer Switch switching performance available within a Pickering switching (Part No. 4x-782B) in Single Format system. Although designed for microwave applications, they have many uses in the RF spectrum where extremely low insertion loss and ultra high isolation are critical.

    Section 2 - Technical Description Functional Description A functional block diagram is provided in Figure 2.1. The module is powered by +5V (PXI), +3.3V and +12V supplies via PCI Bus connectors mounted on the mother board. The interface to the user test equipment is via the front panel mounted SMA, SMA-2.9 or SMA-2.4 connectors.

  • Page 17: 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 18: 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 21: Module Architecture

    Section 4 - Programming Module Architecture The 40/42-782B module is a single or dual microwave transfer switch with the number of switches and maximum frequency handling dependent upon the product order code. They are available in either failsafe or latching versions. The contacts of failsafe relays return to the default state when the system power is removed whereas latching relay contacts retain their last set state when the power is removed.

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 30: 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.
