Power Meters
The analyzer is equipped with an RF power meter and optionally an optical power meter.
The RF power meter performs two different methods of power measurement. The first
is an internal power measurement for standard power testing without the assistance
of external power sensors and the second interfaces with an external power sensor for
high-accuracy power measurements.
The optical power meter measures optical power for single-mode and multimode
connectors via an external optical power sensor.
RF Power Meter (standard)
Internal Power Measurement
• Frequency range: 10 MHz to 4 GHz/8 GHz
• Dynamic range: ‒120 to +20 dBm/+25 dBm
• Measurement type: RMS or peak
External Power Measurement
• JD732B: Terminating power sensor (average)
• JD734B: Terminating power sensor (peak)
• JD736B: Terminating power sensor (average and peak)
– Frequency range: 20 MHz to 3.8 GHz
– Dynamic range: ‒30 to +20 dBm
• JD731B: Directional (through line) power sensor
