Siglent SSA3075X PLUS 7.5GHz spectrum analyzer + FREE TG LICENSE
Siglent SSA3075X PLUS 7.5GHz spectrum analyzer is the newest analyzer that represent the highest bandwidth and can be also be extended with Vector Signal Analysis and other options to increase versatility for meeting the unique challenges of RF circuit design.
Product overview
The SSA3075X Plus is a powerful, flexible spectrum analyzer covering 9 kHz to 7.5 GHz for RF signal and network analysis. An all-digital IF, a standard 20 dB preamplifier and 1 Hz resolution bandwidth combine with a bright 10.1-inch multi-touch display to make precise measurements fast and intuitive — pinch to zoom, drag markers and set limit lines by hand.
A free tracking-generator licence is included for scalar-network measurement, and the platform grows with your work: optional analog & digital modulation analysis, an advanced measurement kit, CISPR-16 EMI pre-compliance and a reflection kit for VSWR and return loss all unlock as software or accessory options.

Mouse and keyboard are supported alongside the touchscreen, and the built-in web server mirrors the screen to any PC, tablet or phone for remote control and file operation. With a low phase noise of < −98 dBc/Hz at 1 GHz, a +14 dBm third-order intercept and a −165 dBm/Hz displayed average noise level, the SSA3075X Plus delivers the dynamic range and repeatability demanded by broadcast, EMI pre-compliance, education, R&D and production work alike.
Key highlights
9 kHz – 7.5 GHz
Full spectrum coverage from 9 kHz up to 7.5 GHz for RF signal and network analysis.
Standard preamplifier
A 20 dB preamplifier is fitted as standard, giving a −165 dBm/Hz displayed average noise level for weak-signal work.
1 Hz minimum RBW
An all-digital IF delivers accurate, repeatable results with resolution bandwidth from 1 Hz to 3 MHz.
Low phase noise
Phase noise of < −98 dBc/Hz at 1 GHz (10 kHz offset) for clean, close-in measurements.
10.1" multi-touch
A bright 10.1-inch capacitive multi-touch screen — pinch to zoom and drag markers; mouse & keyboard supported too.
Free TG & web control
A free tracking-generator licence is included, plus browser remote control on any PC, tablet or phone.
Core capabilities
All-digital IF & 1 Hz RBW
A fully digital IF gives accurate, repeatable measurements and resolution bandwidth from 1 Hz in a 1-3-10 sequence — resolving signals other analysers in this class cannot separate.
Standard preamp & low DANL
The built-in 20 dB preamplifier lowers the displayed average noise level for weak-signal work, while a low phase noise and high third-order intercept keep dynamic range wide.
Tracking generator & reflection
Every model ships with a free tracking-generator licence for scalar-network measurement; add the reflection kit for VSWR, return-loss and Q measurements.
Modulation analysis & EMI
Optional analog (AM/FM) and digital (ASK/FSK/MSK/PSK/QAM with EVM) modulation analysis, an advanced measurement kit and a CISPR-16 EMI pre-compliance mode.
Measurements in action
Screens captured on the SSA3000X Plus — the same measurement engine runs across every model in the series.
