Several Instrument Types Under One Name
This category is an umbrella covering several distinct microwave-frequency measurement instrument types, grouped together because they operate in the same frequency range rather than because they perform the same measurement. Check the specific listing to confirm which measurement function you actually need — a modulation analyzer, a receiver, and a power detector are not interchangeable.
Modulation Analyzers and Vector Voltmeters
The HP/Agilent 8901B measures the modulation characteristics of an RF signal — AM/FM depth, modulation frequency, distortion — for verifying radio transmitters and receivers rather than general spectrum work. Vector voltmeters like the 8405A measure amplitude and phase relationships between two RF signals, a specialized measurement distinct from both modulation and spectrum analysis.
Microwave Receivers and Spectrum Analyzers
The HP/Agilent 8530A microwave receiver and 8569B spectrum analyzer represent the more general-purpose end of this category — frequency-domain analysis instruments for characterizing signals across a microwave frequency range, similar in concept to instruments in our dedicated spectrum and network analyzer categories but built for microwave-specific applications.
Handheld FieldFox-Style Analyzers
The Agilent/Keysight N9917A and N9918B (FieldFox series) combine spectrum analysis, network analysis, and sometimes power meter or interference-analyzer functions into one battery-powered handheld instrument — built for field technicians doing cell site or antenna system work who need several measurement capabilities without carrying multiple separate instruments.
RF Power Sensors and Detectors
Diode detector modules like the 11664A/B pair with a compatible power meter mainframe to measure RF/microwave power at a specific frequency range and level — accessories to a power measurement system rather than standalone instruments. They won't measure anything connected to just a cable with no meter behind them.
Calibration for Microwave Analyzers
Calibration requirements vary by instrument type in this category — a modulation analyzer needs modulation-accuracy verification, a receiver or spectrum analyzer needs amplitude and frequency accuracy checks, and a power sensor needs power-linearity verification against a traceable reference.

Frequently Asked Questions
Is "Microwave Analyzers" one specific type of instrument? +
No, and we'd rather say so directly: this category is an umbrella covering several distinct microwave-frequency measurement instrument types — modulation analyzers, vector voltmeters, microwave receivers, dielectric probes, RF power sensors and detectors, and handheld combination analyzers — grouped together because they all operate at microwave frequencies, not because they do the same job. Check the specific listing to confirm which measurement function you actually need.
What is a modulation analyzer like the HP/Agilent 8901B used for? +
A modulation analyzer measures the modulation characteristics of an RF signal — AM/FM depth, modulation frequency, distortion — used for verifying radio transmitters and receivers rather than general spectrum analysis. The 8901B was a long-standing industry-standard instrument for exactly this in two-way radio and broadcast RF work.
What is a handheld FieldFox-style analyzer good for? +
Units like the Agilent/Keysight N9917A and N9918B (FieldFox series) combine spectrum analysis, network analysis (S-parameters), and sometimes power meter and interference-analyzer functions into one battery-powered handheld instrument, built for field technicians doing cell site or antenna system work who need multiple measurement capabilities without carrying several separate instruments.
What are the RF power sensors and detectors in this category used for? +
Diode detector modules like the 11664A/B pair with a compatible power meter mainframe to measure RF/microwave power at a specific frequency range and power level — they're accessories to a power measurement system rather than standalone instruments, and won't do anything connected to just a cable with no meter behind them.
