2.1 GHz Spectrum Analyzer

The SIGLENT SSA3021X is a 2.1 GHz spectrum analyzer designed for RF signal measurement and analysis. It integrates a tracking generator and pre-amplifier using all digital IF technology. The instrument achieves a displayed average noise level of -161 dBm/Hz typical and phase noise of -98 dBc/Hz at 10 kHz offset typical. Total amplitude accuracy is better than .7 dB with a minimum resolution bandwidth of 1 Hz.

Engineers needing integrated tracking generation

This analyzer suits RF engineers and technicians who require a combined spectrum analyzer and tracking generator for component or antenna characterization. The built-in pre-amplifier supports low-level signal detection across the full frequency range. Buyers who need real-time spectrum analysis with fast FFT processing should look at other instrument classes. Users requiring frequency coverage beyond 2.1 GHz will need a different model.

Bench instrument with calibration certificate

The unit operates as a standalone benchtop tool with a 10.1 inch WVGA display showing 1024 x 600 resolution. A USB cable and power cord provide connectivity and mains power for immediate use. The included NMI traceable calibration certificate ensures measurement confidence without external calibration services. The tracking generator output enables scalar network analysis directly on the instrument.

Questions about this item

What do I need to connect the SSA3021X to a PC for remote control?

A USB cable is included in the box for connecting the analyzer to a computer.

Can I use the built-in tracking generator with older devices that lack a dedicated tracking generator input?

The TG-SSA3000X tracking generator is included and connects directly to the analyzer's front panel for scalar network analysis.

How do I verify the SSA3021X is calibrated and measuring accurately after setup?

An NMI traceable calibration certificate (NIST equivalent) is supplied, confirming amplitude accuracy within < 0.7 dB.
