Chapter 2 Operating Your Frequency Counter

Offsetting a Power Measurement

Offsetting a Power Measurement

You can use the Power Offset (Pwr Offset) function to add or subtract a constant value to/from a power measurement. For example, you can use an offset to compensate for a systematic error, to display the difference in power between two signals, or to compensate for losses and attenuation in cables or components that are between the signal source and the Counter.

To display an offset power measurement, you set the value and sign (+/–) of the offset and turn the Power Offset function on. In the following example, the Power Offset function is enabled first, and the offset value is then entered. However, the order doesn’t matter, so you can also enter the offset value first, and then turn the offset function on.

Power Offset Example

1Connect a signal to the Channel 2 input connector, and activate power measurement by pressing the Display Power key.

The display should look like this (except for the values, which are simulated in the illustration):
