Description
Siglent SSA3021X – 2.1 GHz Spectrum Analyzer with Preamplifier and Tracking Generator

- 2.1 GHz spectrum analyzer
- Includes tracking generator and preamplifier
- All digital IF technology
- -161 dBm/Hz displayed average noise level (Typ.)
- -98 dBc/Hz @10 kHz offset phase noise (1 GHz, Typ.)
Siglent’s SSA3000X family of spectrum analyzers offer a frequency range of 9 kHz to 2.1 or 3.2 GHz. With their lightweight, small size, and user-friendly interface, the SSA3000s present a large, bright easy to read display, powerful and reliable automatic measurements, and plenty of impressive features. Applications include research and development, education, production, maintenance, and pre-compliance testing.
Product Features

Easy to operate, Support four independent traces and cursors
Four selectable color-coded traces can be used for different functions (ie. Max Hold, Min Hold, Clear-Write, Math, Average, etc). Four movable markers.

1 Hz Minimum Resolution Bandwidth (RBW)
RBW: 1 Hz – 1 MHz in 1-3-10 sequence. (Minimum RBW depends on Frequency Span)

-151 dBm Displayed Average Noise Level (RBW=10 Hz)

Phase noise -98 dBc/Hz @ 1 GHz @ 10 kHz offset
Reflection/VSWR, Advanced Measurements/Waterfall Chart and EMI Pre-compliance
Siglent SSA3000X spectrum analyzers come with approximately 40 hours of trial usage for the three options listed below.
- Reflection/VSWR Measurement
- Advanced Measurement/Waterfall Chart
- EMI Pre-compliance Measurement
The trial timer is running when the instrument is powered on. After the trial has expired, the function will be disabled/greyed out. If you would like to purchase these options, they are listed on the accessories section of this page.

On-screen VSWR/Return Loss measurements with the reflection measurement option (SSA3000-REFL)
Available with or without directional coupler.

Advanced measurement kit (AMK-SSA3000X) includes on-screen ACPR measurements
Channel power, Adjacent channel power ratio, TIme domain power, Occupied BW, Third-order intercept, Spectrum monitor (waterfall).

EMI filters and Quasi-Peak detector following CISPR 16 (EMI-SSA3000X)
Comes with EMI report software. Speeds measurement time, generates test reports.
