The E4416A meter and E-series E9320 power sensors continuously 

sample the RF signal at a 20 MHz rate. Similarly, the E4417A samples 

both channels at the same rate. Various trigger methods enable the 

measurement of continuously modulated signals or single events. 

/GCUWTGOGPV)CVGU

A system of gates, controlled by and referenced to a trigger point, is used 

to extract measurement data from the captured trace. The trace data 

within each gate period is subsequently used for the individual 

measurement calculations. Up to 4 gates can be set up for each channel 

(Refer to Figure 36.)

(KIWTG /GCUWTGOGPV)CVGU

With the gates setup as shown in Figure 36 for example, you can 

simultaneously measure:

• The average power level of the pulse: Gate 1, average measurement

• The Peak to average ratio: Gate 1, peak-to-average measurement

• The Pulse droop: Gate 3, average measurement, minus Gate 4, average 

measurement

• The average “off” power level ahead of the pulse: Gate 2, average 

measurement.
