8-16 Triggering Model 6220/6221 Reference Manual
Return to Section 8 topics
For this example, the Model 622x and switching mainframe are configured as follows:
To run this test properly, set up the sweep with 10 points with the desired currents
(see
Section 4).
To start the test, press STEP on the switching mainframe to take it out of idle and
start the scan. The switching mainframes output pulse triggers the Model 622x to
output the sweep point current. The Model 622x then sends an output trigger
pulse to the switching mainframe to close the next channel. This process contin-
ues until all 10 sweep points are swept and channels are sequentially scanned.
Details of this testing process are explained in the following paragraphs and are
referenced to the operation model shown in Figure 8-9.
