It is used for nonlinear measurements with the PNA-Xnonlinear vector network analyzer (NVNA). NVNA requires twocomb generators, one is connected during measurements andanother is used only during calibration. A comb generator is alsoused to characterize the VNA receivers for delay measurementsof frequency converters using PNA-X or PNA instruments and theSMC+Phase measurement class (part of S93083B/A).CalPod calibration refresh modules (8553xB/4xA)PNA-X PNA PNA-LCalPod calibration refresh modules allow in-situ calibrationrefreshes to be performed at the push of a button withoutremoving the DUT or re-connecting calibration standards.CalPods are designed for any measurement situation where itis desirable to ensure that a valid calibration is present beforerecording measurement data. For example, they are useful forremoving environmental effects such as cable movement andthermal-based changes of cables, connectors, and adapters, aswell as connector and switch-matrix repeatability errors. Themodules are especially useful in temperature, or thermal-vacuumchamber testing. CalPod modules are equipped with 2.92 mmconnectors.– 85530B 20 GHz ambient-temperature CalPod– 85531B 20 GHz temperature-compensated CalPod– 85532B 20 GHz thermal-vacuum compatible CalPod– 85540A 40 GHz ambient-temperature CalPod– 85541A 40 GHz temperature-compensated CalPod– 85542A 40 GHz thermal-vacuum compatible CalPod– 85523B CalPod controller (provides control for up to4 CalPods)– 85556A CalPod drive-cable splitter (allows control for up to12 CalPods)– 85554A CalPod drive cable extension (10-meter cascadableextension cable)AccessoriesSolid black series name indicates the feature is available on thatseries, while gray series name with strikethrough indicates thefeature is not available on that series.

Coaxial connectors are SMB-male.The PULSE IN connectors are for controlling the analyzer’sinternal IF gates, which are enabled with S93026B/A and usedwith narrowband detection. The PULSE OUT connectors arefrom the four internal pulse generators, which are enabledwith S93025/26B/A. The PULSE SYNC IN connector is used tosynchronize the internal pulse generators with an external timingpulse. The RF PULSE MOD IN connector controls the internalpulse modulator(s) which are enabled with Options 021 and 022.PNA Family Applications and Options (continued)Pulse I/O adapter (N1966A) simplifies connections
