Option 022 adds an internal pulse modulation capability to the second internal source for pulsed-RF measurements. Option 224 or 400 is required.
With Option 021 and Option 022, the PNA-X provides pulsed stimuli at test port one and two for internal dual-source 2-port test set (Option 224), or test port one and three for 4-port test set (Option 400) for PNA (Option 400, 401, 417, or 419 are required) that allows forward and reverse direction pulse measurements. By combining Option 021 pulse modulator for the first internal source, 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 complete bi-directional pulse measurement capabilities such as pulse average, point-in-pulse and pulse-profile.
