Keithley 2182, User Manual, Page: 132 / 339

For this example, the Models 2182 and 7001/7002 are configured as follows:
Model 2182:
Factory defaults restored (accessed from SHIFT-SETUP)
External scanning, channels 1 - 8, no timer, 8 readings (accessed from SHIFT-CONFIG)
External triggers (accessed from EX TRIG)
Model 7001 or 7002:
Factory defaults restored
Scan list = 1!1-1!8,
Number of scans = 1
Channel spacing = TrigLink
To run the test and store readings in the Model 2182 with the unit set for external triggers,
press STEP or SCAN. The Model 2182 waits (with the asterisk annunciator lit) for an external
trigger from the Model 7001/7002.
Press STEP on the Model 7001/7002 to take it out of idle and start the scan. The scanner's
output pulse triggers the Model 2182 to take a reading, store it, and send a trigger pulse. The
following explanation on operation is referenced to the operation model shown in
Figure 7-8 .
