Agilent/Keysight 71210C – Spectrum Analyzer

The Agilent/Keysight 71210C is a microwave spectrum analyzer engineered for RF and microwave test applications demanding high sensitivity and precise frequency analysis across extended bandwidth. Operating from 100 Hz to 22 GHz with 10 Hz minimum resolution, this instrument delivers fundamental mixing sensitivity of -139 dBm at 1 GHz and -133 dBm at 22 GHz. With optional preamplifier, sensitivity extends to -155 dBm to -150 dBm, enabling detection of low-level signals across the full frequency range.

Technical Specifications

• Frequency Range: 100 Hz to 22 GHz


• Minimum Resolution Bandwidth: 10 Hz


• Mixing Type: Fundamental mixing


• Sensitivity (standard): -139 dBm at 1 GHz; -133 dBm at 22 GHz


• Sensitivity (with preamplifier): -155 dBm to -150 dBm

Key Features

• Dynamic preselector tracking above 2.9 GHz maintains amplitude flatness and accuracy across the microwave band. High sensitivity baseline performance enables detection of weak signals in demanding measurement environments. Preamplifier option extends dynamic range for applications requiring noise floor performance below -150 dBm.

Typical Applications The 71210C addresses RF and microwave characterization tasks including component testing, signal monitoring, and frequency domain analysis where sensitivity and frequency coverage to 22 GHz are required.

Compatibility & Integration Designed as part of the Modular Measurement System (MMS) family, the 71210C integrates with configurable MMS architectures. Programming language compatibility with the 8566B standard enables automated test sequences and system-level control. Note: Product status is obsolete.
