Siglent Technologies has added a pair of RF analysers to its range: an entry-level spectrum analyser, and a lower-end real-time spectrum analyser.

Siglent SSA3000X-R-NA-EU

SSA3032X-R (photo right) is the real-time spectrum analyser, with a maximum bandwidth of 9kHz to 3.2GHz (as opposed to 5GHz or 7.5GHz in the company’s faster real-time (‘-R’) versions).

Specs shared with its two faster cousins include: 1Hz – 3MHz resolution bandwidth (RBW), <-98dBc/Hz phase noise, <0.7dB total amplitude accuracy and -165dBm/Hz DANL (display average noise level).

“With real-time capability, your analyser will capture more data more quickly than traditional swept analysers,” said Siglent. “This allows gap-free capture of spurs and interference sources so that you can find and fix possible issues faster.” 100% POI is 7.2µs.

It sees use in broadcast, cellular communications, near-field communications, spectrum monitoring, R&D, production, maintenance tasks and education.

There is a vector signal analyser (VNA) function for complex impedance measurements, like antenna matching or filter optimisation, and an option is modulation analysis.

Siglent SSA3000XPlus-NA-EUSSA3015X Plus (photo left) is a 9kHz to 1.5GHz spectrum analyser, pitched below 2.1, 3.2 and 7.5GHz versions.

It has 1Hz to 1MHz RBW, <-99dBc/Hz phase noise (typical, 1GHz, 10kHz offset), <1.2dB total amplitude accuracy and -156dBm/Hz DANL.

Unlike the real time instruments, this family has improved accuracy and DANL as you move up the range. That said, this entry-level version beats the more costly ones by 1dBc/Hz in phase noise.

The screen is 10.1in touch, a mouse and keyboard can be attached, and there is an integrated web server.

Tracking generator and pre-amplifier are built-in, then options include an advanced measurement kit (SSA3000XP-AMK) which includes channel power (CHP), adjacent channel power (ACPR), occupied bandwidth (OBW), TOI and waterfall diagram (monitor), as well as harmonic and carrier-to-noise ratio (CNR) measurements.

The extended EMC option adds EMI filter with bandwidths of 200Hz, 9kHz, 120kHz and 1MHz following CISPR16.1 definition. Various EMC standard limits are included.

Vector signal analysis demodulation is another option.
