Staring a Measurement Cycle (triggering the instrument)

Other topics about Making Measurement

Configuring the Instrument to Automatically Perform Continuous Measurement

  1. Select a measurement to be triggered using the :TRIGger:MODE command.

  2. Set the trigger source of the triggered measurement to Internal using the :TRIGger:xx:SOURce command.

  3. Set the continuous initiation mode of the enabled triggered measurement using the :INITiate:xx:CONTinuous command.

Starting Measurement on Demand

  1. Select a measurement to be triggered using the :TRIGger:MODE command.

  2. Set the trigger source of the triggered measurement to Bus using the :TRIGger:xx:SOURce command.

  3. Set the continuous initiation mode of the enabled triggered measurement using the :INITiate:xx:CONTinuous command.

  4. Trigger the instrument when you want to perform measurement. An external controller can trigger the instrument by only a single command.

Using the Averaging Trigger

You can make the E5052B repeat a cycle of waiting for a trigger and performing measurement for the number of times specified by the averaging factor with a single transition to the “Initiate” state. To switch between the averaging trigger mode and the normal trigger mode, use the following command.

•   :TRIGger:AVERage

Averaging trig­ger mode

State transition for each setting

On

Turns on the averaging trigger mode.

The instrument repeats a cycle of "waiting for a trigger" to "performing measurement," as many times as specified by the averaging factor, and then transitions to the “Hold” state.

Off

Turns off the averaging trigger mode.

When the instrument finishes a single cycle of “waiting for a trigger” to “performing measurement,” it transitions to “Hold” state.

 

The following table shows the operational difference between the trigger systems.

Operation of trigger system

Off (Single)

Off

The instrument waits for a trigger only once. When it receives a trigger, it performs measurement and then transistors to the “Hold” state. The averaging factor is not cleared; it is incremented.

On

The instrument repeats a cycle of “waiting for a trigger” to “receiving a trigger” to “performing measurement,” as many times as specified by the averaging factor, and then transitions to the “Hold” state. The averaging factor is cleared before the start of measurement after receiving the first trigger.

On (Continuous)

Off

The instrument repeats a cycle of “waiting for a trigger” to “receiving a trigger” to “performing measurement.” The averaging factor is not cleared; it is incremented.

On

The instrument repeats a cycle of “waiting for a trigger” to “receiving a trigger” to “performing measurement.” The averaging factor is cleared before the start of measurement after receiving the first trigger.
