PIM Analyzer Current Measurement Status

The query returns the current measurement status of the measurement receiver/PIM Analyzer measurement system. Because the measurement system can run for the maximum time duration, the query serves to indicate if the measurement is still in process. This command works with any of the available measurement modes: PIM vs. Time, DTP, and Swept PIM.

0, Measurement is OFF
1, Measurement is ON

Measurement Receiver Measured Value From PIM Master Measurement Setup

This query returns the peak measured value in both dBc and dBm. For example, if the output power is set to 43 dBm and a PIM value of –80 dBm was read, then this command would return: –123.0, –80.0

This command is not supported for the Distance-To-PIM measurement mode. The dBc value should be ignored for the Noise Floor measurement modes.

A return value of –160 dBm for this query indicates that the measurement is invalid.
