  • Latest V0.5.4 hardware plus ESD protection ensures stable professional performance

Spectrum analyser and signal generator

The BFKK TinySA Ultra+ ZS407 is a handheld instrument that combines a spectrum analyser with an integrated RF signal generator. It targets engineers and technicians who need portable frequency-domain measurement and test-signal creation for field or bench work.

Frequency range and scan detail

The analyser covers 100 kHz to 7.3 GHz in ultra mode and 100 kHz to 800 MHz in standard mode, with a calibrated upper limit of 8 GHz. Resolution bandwidth spans 200 Hz to 850 kHz, and the 4.0 inch touchscreen displays up to 450 scan points at 480×320 resolution for spectrum visualisation.

Signal generation headroom

The generator produces MF, HF and VHF sine waves from 100 kHz to 900 MHz, UHF square waves from 800 MHz to 6.3 GHz and mixed signals from 4.4 GHz to 6.3 GHz. Output above 6.3 GHz is not supported, so users requiring continuous coverage to the full 7.3 GHz analysis limit will need a separate source.

Questions about this item

Which frequency mode should I select for testing up to 6 GHz?

Use ULTRA mode which extends the range to 6 GHz, while standard mode covers 100 kHz to 800 MHz.

What does the 7.3 GHz specification mean when I am measuring signals?

The analyser is calibrated up to 8 GHz and can display signals up to 7.3 GHz, with UHF square-wave generation reaching 6.3 GHz.

How does the 200 Hz to 850 kHz resolution bandwidth affect my measurements?

The selectable RBW lets you trade sweep speed for frequency detail, enabling precise SSB two-tone intermodulation tests.
