Triggering Measurements

Trigger Mode Settings for Most Reliable Measurements

Use the following Test Set configuration and trigger mode settings to

get the most accurate, most reliable, fully settled measurement results.

See “Increasing Measurement Throughput” on page 114 for more

information on improving measurement throughput.

1. Turn on all autoranging functions. (This is the Test Set’s default

turn-on and preset state.)

2. Use SINGle RETRiggering.

3. Use FULL SETTling.

4. Individually trigger each measurement.

Measurement Pacing

Measurement pacing can be accomplished by using the IEEE

488.2-1987 Common Commands *OPC, *OPC?, and *WAI. These

commands are implemented within the Test Set using the criteria that

an operation has not completed until

• all active measurements have obtained at least one valid

measurement result

• all signals generated by the Test Set are within specifications.

Refer to the “Common Command Descriptions” on page 89 and the

IEEE 488.2-1987 Standard for more information on using these

commands.
