3.1 Model Selection of Power Sensor
The S2438 series microwave power meter is compatible with the S71710, S81702 and S81703 series power sensors and
the waveguide series MMW power sensor. The specific models and main specifications are shown in Tables 3.1 and 3.2.
The S2438 series microwave power meter includes 4 models, i.e. S2438CA (CW single channel), S2438CB (CW double
channel), S2438PA (CW/peak single channel) and S2438PB (CW/peak double channel), among which S2438CA and
S2438CB can only be connected to the S71710 series CW power sensor while S2438PA and S2438PB can be connected
to all sensors.
