Operating the Counter

Measuring Relative Power

You can measure the difference in power from one measurement to another (drift) using the Relative Power function. You do this by pressing the Shift and Rel Pwr (Offset On/Off) keys, as shown in the diagram below (this example assumes that a signal is currently applied to Channel 2).

The Counter stores the current power reading when you press the Rel Pwr key. It then subtracts this value from all subsequent readings and displays the difference until you press the Rel Pwr key again.

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 or to display the difference

 

in power between two signals.

 

 

NOTE

The Power Offset and Relative Power functions can be used simultaneously.

 

To display an offset power measurement, you need to set the value and

 

 

sign (+/–) of the offset and to turn the Power Offset function on. In the

 

following diagram, the Power Offset function is enabled first, and the
