Signal Hawk LogoSpectrum Analysis - Signal Hawk.

The Bird SignalHawk™ is unique in the world of RF Spectrum Analysers in that the same instrument is available in 3 different packages.

The SH-36 Series, SignalHawk™ line of Spectrum Analysers and Vector Network Analyser's are the most user-friendly and accurate hand-held test solution available for installing, maintaining and troubleshooting all segments of RF communication systems.

Signal Hawk™ Packages Include:Application Note


Hand Held Spectrum Analyser with Optional VNA & Power Meter

Bird Technologies SignalHawk Analyses radio frequency spectrum. Measures intended and interfering signals. Allows set-up of parameters such as frequency, amplitude, and markers.
Graphically displays signal amplitude vs. frequency and saves traces.

SH-36S
SH-36S: Spectrum Analyser
  • Spectrum Analyser, 100KHz to 3.6GHz.

SH-361S: Spectrum Analyser & 1-Port VNA
  • As SH-36S, plus one-port VNA additionally measuring Match (VSWR & Return Loss dB), Distance-to-Fault (DTF), Cable Loss

SH-362S: Spectrum Analyser & 2-Port VNA
  • As SH-36S, plus two-port VNA additionally measuring Gain & Loss (Amplifier Gain/loss -90dB to + 50dB, Insertion Loss, Antenna Isolation) & 12/24 V Internal Bias-Tee

SH-362: 2- Port VNA (1.6MHz to 3.6GHz)
  • As SH-362S but without Spectrum Analyser function

Rack Mount Signal Hawk SH36S-RM

The SignalHawk Series of spectrum analysers has expanded to include a dedicated rack-mount version, which has been built using the same analysis engine the found in other SignalHawks, but with no display or keypad.

The SH-36S-RM includes Ethernet and USB connections for local or remote communication. Over an Ethernet network, you can remotely analyse the performance of your system and diagnose problems from any computer on your network, whether in the same room or halfway across the country or even further afield.

Key Features:
Rack Mount Signal Hawk
  • Fast, Accurate, and Sensitive: 66 dB Dynamic Range and -135 dBm Noise Floor
  • Minimal Rack Space Required: Only 2 RU
  • Eliminates trips to difficult remote locations
  • Same “Spectrum Analyser” functionality as our hand held unit all from your office PC
  • Multiple sites can be monitored from one centralized location
  • Along with our BPME you can view your RF Spectrum and be alerted of any RF Power alarm - A TOTAL 1-STOP PACKAGE
  • Built in FCC Compliance Masks
  • Waterfall display
