Saelig has introduced the SIGLENT SHA800A series, handheld portable spectrum analysers which form a powerful, versatile choice for benchtop and field RF measurement applications.

SHA800A analysers combine the capabilities of a Spectrum Analyser, a Vector Network Analyser, and a Cable/Antenna Tester all in one intuitive handheld package. With a frequency range up to 7.5GHz, these analysers deliver reliable automatic measurements and multiple modes of operation. The spectrum analyser includes a built-in amplifier and independent signal source, fast scanning speed, and 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 analyser:

Frequency range from 9kHz up to 3.6/7.5GHz,
Displayed average noise level (Typ.), -165dBm/Hz
Offset phase noise (1GHz, Typ.), -104dBc/Hz.@10kHz
Minimum Resolution Bandwidth (RBW) 1Hz up to 10MHz
Preamplifier and independent signal source up to 7.5GHz,
GPS positioning and logging

Cable and antenna test:

Frequency range from 100kHz up to 3.6/7.5GHz
Distance to fault and time domain analysis
Vector network analyser
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 analysers 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 analysers.
