Triggering
Model 6485 Picoammeter Instruction Manual
Details of this testing process are explained in the following paragraphs and are referenced
to the operation model shown in
.
A.
Operation of Model 6485 starts at point A in the flowchart where it waits for an
external trigger.
B.
Pressing STEP takes Model 7001/2 out of idle and places operation at point B in the
flowchart.
C.
For the first pass through Model, the scanner does not wait at point B. Instead, it
closes the first channel (point C).
D.
After the relay settles, Model 7001/2 outputs a trigger pulse. Since the instrument
is programmed to scan 10 channels, operation loops back to point B, where it waits
for an input trigger.
E. and F.
With Model 6485 at point A, the output trigger pulse from Model 7001/2 triggers a
measurement of DUT #1 (point E). After the measurement is complete, Model 6485
outputs a trigger pulse and then loops back to point A, where it waits for another
input trigger.
The trigger applied to Model 7001/2 from Model 6485 closes the next channel in the scan,
which then triggers Model 6485 to measure that DUT. This process continues until all 10
channels are scanned and measured.
