Theory of Operation

Measurement Process

The 7027 measures the average power of up to four states within a pulse 
period, see 

Figure

  8

. Each state is defined with begin and end times. The begin 

and end times are referenced to the internal reference signal or may be 
referenced to an external sync pulse.

State Average Measurements

The average pulse power measurement interval for each state begins at the 
user specified begin time and ends at the user specified end time. There may be 
four different states specified, each with a begin and end time.
