    Module Descriptions generator card (HFS 9DG2). Each HFS 9009 has one CPU card, one time base card, and up to nine generator cards. CPU Card The CPU receives commands for pulse output parameters from the front panel, the GPIB, or RS-232 interfaces. The CPU creates a series of time base and generator card commands which are then transmitted via the VXI Bus to set up the generator outputs.

  • Page 95: Troubleshooting

    Power-On Diagnostics Power-on diagnostics execute automatically whenever the mainframe power is switched on. The HFS 9009 uses three stages of diagnostics which run consecu- tively: the kernel test, controller test, and self test. Diagnostics advance to the next stage only if the preceding stage does not detect an error. In self-test diagnostics, once an error message is displayed on the screen, you can request that the diagnostics continue.

  • Page 96: Self-Test Diagnostics

    IEEE 488.1/488.2 standards. When the test is complete, the HFS 9009 returns to the state it was in prior to the self test. The test response is a value as described in Table 6–1.
