## About the Siglent SSA5085A

In summary, the Siglent SSA5085A is a benchtop spectrum analyzer covering 9 kHz to 26.5 GHz with a -165 dBm/Hz typical displayed average noise level, -105 dBc/Hz typical SSB phase noise at 1 GHz / 10 kHz offset, and 25 MHz of standard analysis bandwidth (40 MHz optional). It supports real-time spectrum analysis with a 7.20 µs 100% probability-of-intercept minimum signal duration, analog modulation analysis (AM, FM, PM), vector digital modulation analysis (ASK, FSK, MSK, PSK, QAM), and CISPR 16-1-1 EMI pre-compliance, on a 12.1 inch multi-touch screen with HDMI output and web-browser remote control.

### What is the Siglent SSA5085A used for?

The SSA5085A is used for RF spectrum and signal analysis including channel power, ACPR, occupied bandwidth, harmonic, and third-order intercept measurements, plus real-time captures of hopping signals, transient interference, and intermittent emissions that a strictly swept analyzer cannot reliably catch. Per the datasheet, applications include broadcast monitoring, cellular site work, IoT device characterization, WLAN and Bluetooth surveying, education, production test, and field maintenance.

### How does the SSA5085A compare to a swept-only analyzer?

A swept analyzer measures one narrow segment at a time and steps through the span sequentially, so short events between sweeps are missed. The SSA5085A with the SSA5000A-RTA1 option performs up to 150,000 FFTs per second over a 40 MHz analysis bandwidth and guarantees 100% probability of intercept for signals as short as 7.20 µs — suitable for frequency-hopping radios, radar pulses, and intermittent interference. Per the datasheet, the SSA5085A delivers -165 dBm/Hz typical DANL with preamp on, +15 dBm typical TOI from 50 MHz to 7.22 GHz, residual response under -90 dBm, RBW from 1 Hz to 10 MHz in 1-3-10 sequence, and CISPR 16-1-1 EMI filters at 200 Hz, 9 kHz, 120 kHz, and 1 MHz. The 10 MHz reference can be locked externally, and SCPI / IVI / LabVIEW remote control is supported over USB-TMC, VXI-11, socket, and Telnet, with an optional USB-GPIB adapter.

### Where does the SSA5085A fit in an RF lab?

-   Transmitter verification, spurious checks, harmonic and TOI characterization on RF designs up to 26.5 GHz.
-   Real-time monitoring of hopping radios, radar pulses, and intermittent interference.
-   EMI pre-compliance with CISPR 16-1-1 quasi-peak detection and pre-loaded EN 55022, GB 9254, and FCC Part 15 limit standards (SSA5000-EMI).
-   Modulation quality analysis (EVM, magnitude error, phase error, IQ offset, SNR) for digital wireless designs.
-   Education and research benches that benefit from a 12.1 inch multi-touch screen and web-browser remote control.
