This section describes how to verify the timing functionality of the Enhanced
Monitor. This test outputs a waveform on pin 25 of the Diagnostic Connector with a
16msec period for 10 seconds. Use a counter to determine accuracy.
1. Connect a counter to pin 25 of the Diagnostic Connector on the front panel of
the mainframe (pin 18 is ground). Set the counter to measure period.
2. Execute the command:
TEST:TIME?
3. The average period should be 16mS ±1 S.
This concludes the Timer Test. If this test fails, return the mainframe for service to
your HP Sales and Service Office.
Table 4-3 is a form you can copy and use to record calibration and performance
verification results for the Enhanced Monitor.
