RF Spectrum Analysis at Your Fingertips

SH-42S-TC, 10 MHz to 4.2 GHz RF Spectrum Analyzer
Boost your readiness with a handheld spectrum analyzer, flexible enough to meet the needs of novices & experts alike.

  • Easily scan, classify and locate signals of interest in the field environment
  • Endure the harshest working conditions with real-time RF spectrum analyzers designed for durability – completely sealed, rugged & weather-resistant
  • Measure RF power using an optional Bird power sensor
  • Measuring slight changes in impedance will help uncover passive intermodulation distortion and adjacent channel power problems for digitally modulated signals
  • Scan the environment to discover spectrum events other analyzers will miss with predefined measurements
  • Big on performance with industry leading dynamic range, sweep speed and amplitude accuracy
  • Rugged high-resolution touch screen display simplifies the setup and data capturing
  • Save time and ensure consistent results by automating routine tasks for basic spectrum analysis
  • Long operating life, up to 6 hours with rechargeable battery
  • Measure Return Loss and Distance to Fault
  • Calibrate in the field with included Cal Combo
  • Lightest, all-in-one analyzer at only 2.8 lb (1.25 kg)
