Trigger Mode and Measurement Speed

There are two generalized scenarios which can be described for HP-IB

triggering control. The first is to have the Test Set return measurement

results as fast as possible and assume that the control program will

handle all transient settling and value tolerance activities. The second

scenario is to have the Test Set return the most reliable, accurate, fully

settled measurement results that it can, even if it takes some time to do

this.

Trigger Mode Settings for Fastest Measurements

Use the following Test Set configuration and trigger mode settings for

the fastest possible measurement speed. See “Increasing Measurement

Throughput” on page 114 for more information on improving

measurement throughput.

1. Range hold all autoranging functions and set ranges through HP-IB.

This avoids autoranging delays.

2. Use REPetitive RETRiggering. This avoids Trigger Event processing

delays.

3. Use FAST SETTling. This avoids the signal transient settling

delays.

4. Turn off all measurements that are not required. This avoids any

delays caused by contention for measurement resources within the

Test Set.

1. Using FAST settling increases the possibility that transient signal conditions

which occur during the measurement cycle will be included in the measurement

result.
