Overview of Trigger Source

You can set the trigger source for calibration before executing calibration.

You can select it from Internal or System. Setting it to System allows you to use the same trigger source setting for calibration and measurement.

You can set the trigger source for calibration (which is usually set to Internal) to System which allows you to generate triggers at any timing from a PC for external control or from the front panel for calibration in the same way as for measurement.

The setting of the trigger point and trigger averaging is also applied to the trigger for calibration. When the trigger source for calibration is set to System and the trigger source for measurement is set to External or Manual with the point trigger function set to ON, a trigger is required for each measurement point during calibration. When the averaging trigger function is set to ON, the sweep is performed the number of times specified by the averaging factor for a single trigger during calibration.

For the following types of calibration, the setting of the trigger source does not take effect. Those calibration operations are controlled by the internal trigger.

•  Calibration using ECal

•  Power calibration

•  Receiver calibration

•  Mixer converter calibration

Setting Trigger Source

Follow these steps to set the trigger source for calibration:

1. Press Cal.

2. Click Cal Trig Source, then select the trigger source you want to use.
