Counters

Programmable counters are used to repeat operations within the trigger model

layers. For example, if performing a 10-point sweep, the trigger counter would be

set to 10

(TRIGger:COUNt 10). Operation will stay in the Trigger Layer until the 10

source-delay-measure points of the sweep are performed.

If you wanted to repeat the sweep three times, the arm counter would be set to

three (ARM:COUNt 3). Three 10-point sweeps can then be performed for a total of

30 source-delay-measure actions.

The maximum buffer size for the SourceMeter is 2500 readings. The product of the

finite values of the two counters cannot exceed 2500. For example, if you set an

arm count of two, the maximum trigger count will be 1250 (2500 / 2 = 1250). How-

ever, you can set the arm count to infinite (INF). With an infinite arm count, the max-

imum trigger count is 2500.

NOTE With front panel operation only, when a sweep is configured, the trigger

model settings will not change until the sweep is started. After the sweep

is finished, the trigger model will reset to the previous settings.
