Performance Verification

keys in the input section of the Analyzer until the PHASE light in the ERROR HISTORY section illuminates. Manually return the Analyzer delay setting to that recorded above. Verify that the PHASE light can be extinguished by the ‘CLEAR’ key.

Confirmation of Selectable Analyzer Terminations

qStep 41: Set the Generator and Analyzer to Factory Default Settings. Confirm that the Analyzer F2 LED is not lighted.

qStep 42: Push the Analyzer V-TERM button and confirm that the LCD displays GND.

qStep 43: Perform the following actions for each termination listed:

a)Select the Analyzer termination by using the ‘UP’ and ‘DOWN’ arrow keys in the INPUT section.

b)On the Generator, select PN15, wait a few seconds, then select PN7. Use the ‘UP’ and ‘DOWN’ arrow keys to select the different PN values.

c)Wait for the Analyzer LOCK light to come on.

d)Confirm the Analyzer threshold display falls within the limits shown in the Termination Threshold Limits table.

e)Press F2 on the Analyzer to select CLOCK inputs and confirm that the F2 LED is lighted, and repeat steps a) through d).

Note

The threshold limits listed assume that the Generator is set to default

Amplitude and Baseline Offset.

Analyzer Termination Threshold Limits

Analyzer Termination	Analyzer Threshold Limits
50 Ohm to GND	0 V ± 300 mV
50 Ohm to −2 V	−1.0 V ± 300 mV
AC	0 V ± 300 mV

qStep 44: Set the Generator and Analyzer to Factory Default Settings.

qStep 45: Disconnect the cable from the DATA THRESHOLD on the rear panel of the Analyzer and connect it to NOT DATA on the front panel of the Generator.

qStep 46: Select PN15 on the Generator.

qStep 47: Verify that the Analyzer LOCK light illuminates.

qStep 48: Repeat Steps 45 and 46 for all PN values.
