GAIN COMPRESSION MEASUREMENT CAPABILITY

The 373XXA simplifies amplifier Gain Compression and AM/PM measurements. Once an appropriate power and frequency schedule is selected, a power meter calibration, at a set level, will calibrate the linear VNA receiver chan- nels, to accurately measure power in dBm. The 37300A supports the HP437B, and Giga-tronics 8540B series power meters. To measure power, b2/1, a user defined pa- rameter, is automatically selected.

Swept Power Gain Compression: The 373XXA will dis- play traditional Power out vs. Power in or Phase vs. Power in, at one of up to 10 selectable frequencies. A separate screen will easily show Power out and Power in at 1 dB, or selected level Gain Compression, for all entered frequen- cies. (Check figure below).

Swept Frequency Gain Compression: Once Gain is measured at the starting power, the user increments Power in, observing Normalized Gain vs. Frequency. This aids in
