Functions & Characteristics

Intuitive menu, easy-to-use, support four traces and cursors independently

System interface shows a simple design style. The menu layout is optimized to display an informative one-page operation. Four traces are classified by color, which helps users to distinguish appropriate spectra changes. The screen employs powerful cursor – assisted measurements. Data and waveforms can be displayed on the screen simultaneously.

10 Hz Minimum Resolution Bandwidth (RBW)

Digital IF technology offers a minimum bandwidth of 10Hz, allowing excellent signal resolution when separation of closely spaced signals is required.

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

Built in high-performance RF front-end, SSA3000X series offer low background noise, and a standard built-in preamplifier. The overall high sensitivity improves weak signal monitoring.

Phase noise -98 dBc/Hz @1 GHz @ 10 kHz offset

Excellent phase noise performance enables users to evaluate most synthesizers and signal generators.


Demodulation at the zero span setting

When the spectrum analyzer is set at zero span, the detector can demodulate the input signal enabling users to observe the modulated signals on screen over time. The SSA3000X includes a front panel audio output jack for listening to AM and FM demodulated signals.

Advanced power measurement, calculate the ACPR parameters

Radio communication standards maintain strict requirements for output power and adjacent channel power leakage. The optional advanced power measurement kit can measure channel power, adjacent channel power ratio, occupied bandwidth, time domain power and other parameters to ensure system performance.


Reflection measurement, acquire characteristic curve of the Return Loss

The optional reflector kit can easily measure S21, S11, and acquire characteristic curve of the Return Loss and VSWR.


EMI filter, Quasi Peak detector with limit template following CISPR 16

The optional EMI Pre-compliance Measurements Kit offers Quasi-Peak detector and EMI filters (200 Hz, 9 kHz, 120 kHz, -6 dB bandwidth). Importing stored limit templates makes it easy to evaluate EMI levels for pre-compliance testing.
