Confirmation of Selectable Analyzer Terminations
q Step 41: Set the Generator and Analyzer to Factory Default Settings. Confirm that
the Analyzer F2 LED is not lighted.
q Step 42: Push the Analyzer V-TERM button and confirm that the LCD displays
GND.
q Step 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.
