This Visual Basic example shows you how to configure the PNA-X internal pulse generators and modulators to make wideband pulsed measurements in pulse profile mode using the PNA-X.
Visit the VNA website where you can download a free Wideband Pulsed Application that performs this measurement on the PNA-X.
