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
