To avoid electric shock, tighten the module mounting screws after installing the module into the mainframe to ensure that the front panel is properly grounded. Note. There are two labeled ejector handles on the card. To install the card correctly, make sure the ejector labeled “VX4357” is at the top. Note. To maintain proper mainframe cooling, unused mainframe slots must be covered with the blank front panels supplied with the mainframe.
Appendix E: Performance Verification Procedure The performance verification procedure for the VX4357 Relay Switching Module checks that the module is operating within specification. Conventions Used In This Procedure Please familiarize yourself with the following conventions which apply throughout this procedure: All control of the VX4357 Module will be accomplished through a VXI Slot 0 device.
Appendix E: Performance Verification Procedure Equipment Required Table 1–1 lists the equipment required for the performance and verification procedure. Table 1–1: Equipment Required Required tools and equipment Part number VXI Mainframe (such as the Tektronix VX1410) n/a VXI Slot 0 with resource Manager (Tektronix VX4521) and appropriate cables and interface cards. n/a Connector, DD-50P n/a VX1785S connector n/a Talker/Listener (Send/Read) n/a 4.
Appendix E: Performance Verification Procedure Relay Resistance Test: Channel 00 1. Place the DD-50P connector onto P4. 2. Place the DMM + side to the pigtail labeled N.C., and place the DMM – side to DD-50P pin-2 (wiper Channel 00). 3. The DMM will read less then 400 milliohms. 4. Send “C0lf” (Close relay CH00) to the VX4357. 5. The DMM will read greater then 10 Gigohms. 6. Send “Q0lf” (Query relay CH00) to the VX4357. 7. Read “1 crlf” (Relay CH00 is closed). 8.
Appendix E: Performance Verification Procedure Delay Command Test 1. Send “Rlf” (Reset the VX4357) to the VX4357. 2. Send “D1000C0C1” (Delay, Close CH00 and CH01 on the VX4357) to the VX4357. Monitor the time difference between CH00 LED to lit and CH01 to lit. This time will be approximately 1 second. 3. Send “Tlf” (Delay Time of the VX4357) to the VX4357. 4. Read “1000 crlf” (Time Delay programmed to 1000 milliseconds).
