About the Siglent SSA5083A

In summary, the Siglent SSA5083A is a benchtop spectrum analyzer covering 9 kHz to 13.6 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 SSA5083A used for?

The SSA5083A 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 SSA5083A 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 SSA5083A 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 SSA5083A 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 SSA5083A fit in an RF lab?

• Transmitter verification, spurious checks, harmonic and TOI characterization on RF designs up to 13.6 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.
