​​​​​​​SHA800A analyzers combine the capabilities of a Spectrum Analyzer, a Vector Network Analyzer, and a Cable/Antenna Tester all in one intuitive handheld package. With a frequency range up to 7.5 GHz, these analyzers deliver reliable automatic measurements and multiple modes of operation. The spectrum analyzer includes a built-in amplifier and independent signal source, fast scanning speed, high sensitivity, and can monitor RF broadcasts, perform channel power scanning, power monitoring, wireless interference location, electromagnetic compatibility measurements, and other functions. The cable and antenna testing function includes built-in DC voltage bias, with a 1-path-2-port vector network analysis function. It can measure TDR, VSWR, debug port matching issues, perform insertion loss measurements, tower amplifier debugging, cable fault location, Smith charts, etc. 

With two models (SHA851A/SHA852A) the specifications include:

Spectrum Analyzer:

  • Frequency Range from 9 kHz up to 3.6/7.5 GHz,
  • Displayed Average Noise Level (Typ.), -165 dBm/Hz
  • Offset Phase Noise (1 GHz, Typ.), -104 dBc/Hz.@10 kHz
  • Minimum Resolution Bandwidth (RBW) 1 Hz up to 10 MHz
  • Preamplifier and independent signal source up to 7.5 GHz,
  • GPS positioning and logging

Cable and Antenna Test

  • Frequency Range from 100 kHz up to 3.6/7.5 GHz,
  • Distance To Fault and Time Domain Analysis
  • Vector Network Analyzer
  • Bias out up to 32VDC
  • Typical working time 4 hours,
  •  Weight 7lb
  • 8.4” Multi-Touch Screen, Mouse and Keyboard supported

The explosion of RF Technologies such as 5G and IoT have created an extremely complicated electronic measurement environment. Monitoring and debugging these applications are increasingly shifting from laboratories and workstations to on-site and outdoor applications, requiring reliable handheld measurement instruments. Applications for the SHA800A analyzers include communication engineering, telecom operation and maintenance, radio management, factory production, education and teaching, and many others. They provide a capable and more economical alternative to other handheld analyzers. Siglent SHA800A Analyzers are available now from Saelig Company, Inc. For detailed specifications, free technical assistance, or additional information, please contact Saelig at 1-888-7SAELIG, via email: [email protected], or visit
