Pulse Rise Time, Fall Time and Overshoot Measurement
The following procedure lets you measure the rise time, fall time, and overshoot of the MG362x1A’s pulse
modulated RF output.
Repeat the measurements of the pulse rise time, pulse fall time, and pulse overshoot based on the DUT
frequencies in test records.
Pulse Rise Time
