SHA850A Series
A rugged handheld that carries a full spectrum analyzer and a cable-and-antenna tester up the tower and out into the field. Covering 9 kHz to 3.6 or 7.5 GHz with a −165 dBm/Hz noise floor, −104 dBc/Hz phase noise and a standard preamplifier, it runs on an 8.4-inch multi-touch screen, weighs just 3.2 kg and works about four hours on a charge. Add the optional vector-network-analyzer, modulation-analysis, independent-source, DC-bias, GPS and mapping licences and one instrument covers install, commissioning, maintenance and interference hunting.

Add the optional vector-network-analyzer, modulation-analysis, independent-source, DC-bias, GPS and mapping licences and one instrument covers install, commissioning, maintenance and interference hunting.
Both models share the same handheld platform, 8.4-inch touch interface and licence set, so you choose on frequency — then add the VNA, modulation, source, DC-bias, GPS and mapping options as the job demands. siglent.eu is the official EU distributor, with stock, warranty and local support.
Key highlights
Handheld & field-ready
8.4-inch multi-touch screen, 3.2 kg and about four hours of battery — built to leave the bench and climb the tower.
Analyzer + cable/antenna tester
Spectrum analysis and cable-and-antenna testing (VSWR, return loss, DTF, cable loss) are standard on every unit.
Optional 1-path-2-port VNA
Add the VNA licence for vector S11/S21 measurement with up to 114 dB dynamic range.
Interference hunting
Optional GPS positioning and indoor/outdoor maps log and locate signals out in the field.
Models in the series
Choose by frequency — the SHA851A upgrades to 7.5 GHz with the F2 licence.


Core capabilities
9 kHz – 7.5 GHz with −165 dBm/Hz DANL, −104 dBc/Hz phase noise, 1 Hz – 3 MHz RBW and a standard preamplifier.

Features in depth

Built for the field
An 8.4-inch multi-touch display, a rugged 3.2 kg body and roughly four hours of battery mean the SHA850A goes where the signal is — up the mast, out to the site or into the equipment room — with mouse and keyboard supported when you need them.
- 8.4-inch capacitive multi-touch screen
- 3.2 kg net weight, ~4 h typical battery
- Mouse & keyboard supported
- Standard preamplifier for weak-signal work in the field
Two instruments in one: analyzer + cable/antenna
Spectrum analysis and cable-and-antenna testing are both standard, so a single handheld commissions and maintains RF systems: sweep the spectrum, then check the feedline and antenna without swapping tools.
- Spectrum: channel power, ACPR, harmonics, TOI (with AMK)
- Cable & antenna: VSWR, return loss, cable loss
- Distance-to-fault (DTF) and TDR to locate faults
- Optional 1-path-2-port VNA, S11/S21, 114 dB dynamic range


Every input and output
The top panel carries the whole connector set — two N-type RF ports for the analyzer, source and 1-path-2-port VNA, reference and trigger inputs, GPS and DC-bias, USB, LAN and audio — so the SHA850A drops straight into a field or bench setup.
- RF In / Port 2 and Source / Port 1 — two N-type ports (max +30 dBm and +27 dBm, 50 VDC) for the analyzer input, tracking source and 1-path-2-port VNA
- Ref In & Trig In (BNC) — lock to a 10 MHz house reference and trigger externally
- GPS Ant (SMA) for positioning & logging, and Bias Out (SMA) delivering 12–32 V DC to tower-mounted amplifiers
- USB-C device port (PC / remote control) and USB-A host (storage, mouse & keyboard)
- LAN (RJ-45) for LXI / web-browser remote, plus a 3.5 mm headphone jack
- 9–12 VDC (4 A) power input and a Kensington security-lock slot

Frequently asked questions
Frequency range: the SHA851A covers 9 kHz to 3.6 GHz and the SHA852A to 7.5 GHz. Everything else — the 8.4-inch touch platform, cable-and-antenna tester, preamplifier and options — is identical, and the SHA851A upgrades to 7.5 GHz with the F2 licence.
Yes. The SHA850-F2 licence lifts an SHA851A from 3.6 GHz to the full 7.5 GHz, so you can buy the lower model now and extend when you need it.
Yes — spectrum analysis and cable-and-antenna testing are both standard. You get VSWR, return loss, cable loss, distance-to-fault (DTF) and TDR through the N-type port, and an optional 12–32 V DC bias output for tower-mounted amplifiers.
With the SHA850-VNA licence it becomes a 1-path-2-port vector network analyzer, measuring vector S11 and S21 with up to 114 dB dynamic range — useful for filter, component and antenna characterisation in the field.
It has an 8.4-inch multi-touch screen, weighs 3.2 kg and runs about four hours on battery. Add the GPS and MAP licences to log positions and overlay signals on indoor/outdoor maps for interference hunting and site survey.
