10-12 Triggering
Operation
1. To store the readings in the SourceMeter buffer, press STORE, and set the buffer size
for 10. When ENTER is pressed, the asterisk (*) annunciator will turn on to indicate the
buffer is enabled. See Section 8 for details.
2. Turn the SourceMeter OUTPUT ON. The SourceMeter waits for an external trigger
from the switching mainframe.
3. Press STEP on the Model 7001/7002 to take it out of idle and start the scan. The scan-
ner's output pulse triggers the SourceMeter to take a reading and store it. The Source-
Meter then sends a trigger pulse to the switching mainframe to close the next channel.
This process continues until all 10 channels are scanned, measured, and stored.
Details of this testing process are explained in the following paragraphs and are referenced
to the operation model shown in Figure 10-7.
A) Turning the SourceMeter OUTPUT ON places it at point A in the flowchart, where it
waits for an external trigger.
B) Pressing STEP takes the Model 7001/2 out of the idle state and places operation at point
B in the flowchart.
