Option 021 adds an internal pulse modulation capability to the first internal source for pulsed-RF measurements.
With Option 021, the PNA/PNA-X provides pulsed stimuli at test port one that allows forward direction pulse measurements. By combining Option 025 internal pulse generators and Option 008 pulse measurements application, the PNA/PNA-X can be a fully integrated, fast and accurate pulse measurement system, which provides full pulse measurement capabilities such as pulse average, point-in-pulse and pulse-profile.
