9-10 Stepping and Scanning
External scanning
Figure 9-3 summarizes the front panel operations to configure a scan for the “ External
triggering example ” provided in Section 7 . In that example, the Model 2182 is used to scan and
measure eight DUTs switched by a Model 7168 Nanovolt Scanner card installed in a
Model 7001/7002 Switch System.
Figure 7-6 and Figure 7-7 show the signal and trigger
connections, while Figure 7-8 shows trigger model operation for the test.
Both instrument setups assume factory defaults. Note that Channel 1 of the Model 2182 must
be used for external scanning.
1. On the Model 7001 Switch System, enter a scan list of channels 1 to 8 on card 1.
2. Also on the Model 7001, configure the instrument for Trigger Link triggers and one scan
of eight channels.
3. On the Model 2182, configure an external scan of the first eight channels.
4. Set the Model 2182 for external triggers by pressing EX TRIG.
5. Press STEP or SCAN on the Model 2182. The asterisk and STEP or SCAN annunciator
will light.
6. Press STEP on the Model 7001 to start channel closures.
7. After the scan, you can recall eight readings from the Model 2182 buffer.
