  • Page 69: Appendix F - Performance Verification Procedure

    Module verify that the module is operating within specification. Conventions Used In This Procedure All control of the 73A-308 Module will be accomplished through a VXI Slot 0 device. ASCII characters will form the commands sent to control the module and ASCII charac- ters will be read from the module.

    1. Remove power from the VXI system, then reapply power. The FAIL LED will be briefly lit in red during power up. 2. When the following command is sent to the 73A-308, the MSG LED will flash for about a half second.
  • Page 71 ” (Selfttest) to the 73A-308. 2. Read “READY ”. crlf a. If the 73A-308 returns another ASCII string, the built in self test failed and the string indicates what the failure was. 3. Send: “QRB ” (Query Read Back status) to the 73A-308.
  • Page 72 2. Connect the +5 V to P4 pin 50. 3. Connect the ground from the power supply to P4 pin-4 and pin-5. 4. Send “D ” (Disable all outputs) to the 73A-308. 5. Send “CB0 ” (Close Bank 0) to the 73A-308.
  • Page 73 +5V source. 7. Send “E ” (Enable all outputs) to the 73A-308. 8. Measure the voltage at each P4 pin shown in Table 1–2. The voltage at each pin will be less than +500 mV.
  • Page 74 31. Send “O4 ” (Open 4) to the 73A-308. 32. Use a DMM and measure the voltage at BITs 0–1, 0–2, 0–4, 0–8, and 1–1 (refer to TABLE 4–1). The voltage on these pins will be the same as the +5 V source.

  • Page 75: High Voltage Test

    High Voltage Test 1. Send “R;E;D ” (Reset, enable and then disable all outputs) to the 73A-308. 2. Connect one end of a 165 , 15 W resistor to a +50V power supply and also connect the +50 V to P4 pin-50.
  • Page 76 18. Measure the voltage at P4 pin-43. The voltage will be less than +500 mV. 19. Send “R;E;D ” (Reset, enable and then disable all outputs) to the 73A-308. 20. Connect the 165 , 15 W resistor from the +50V, to P4 pin-46, Relay Driver 24.
  • Page 77 36. Measure the voltage at P5 pin-36. The voltage will be less than +500mv. 37. Send “R;E;D ” (Reset, enable and then disable all outputs) to the 73A-308. 38. Connect the 165 , 15 W resistor from +50 V, to P5 pin-40, Relay Driver 48.
  • Page 78 60. Measure the voltage at P5 pin-49. The voltage will be less than +500 mV. 61. Send “R;E;D ” (Reset, enable and then disable all outputs) to the 73A-308. Triggering This tests the TTLTRG lines on the VXI backplane. Steps 2 through 8 verify that the output will not go active until a trigger is received on the selected TTLTRG line.
  • Page 79 2. Send a WORD SERIAL COMMAND “Read STB” (command 0xCFFF) to the 73A-308 and the query byte returned will have bit 6 cleared ignore all other bits. If this is the case then an interrupt has not been generated, otherwise the test failed.
