Rohde & Schwarz 13.6 and 20 GHz handheld spectrum analysers

Rohde & Schwarz has added two models to its R&S FSH range of handheld spectrum analysers: the R&S FSH13 covering the range from 9 kHz to 13.6 GHz and the R& S FSH20 covering the range to 20 GHz. For maximum sensitivity, both models are equipped with an amplifier that can be activated, and users can apply the analysers’ wide range of measurement features up into the microwave range.

The portable spectrum analysers can be used for performing measurements on base stations, for maintaining and installing transmitter systems, and for analysing signal quality. The compact units integrate numerous measurement functions that can be used to analyse transmit signals and interference, measure performance and more.

The spectrum analysers support all common wireless communications standards. With their higher frequency range, the R&S FSH13 and R&S FSH20 can also be used for microwave applications up to 13.6 and 20 GHz, respectively. In addition, the analysers are now able to measure disturbance signals in wireless communications networks, such as UMTS up to the fifth harmonic. The analysers are also suitable for measurements performed during the installation and maintenance of satellite communications and radar systems.

The devices have a sweep speed roughly four times faster than comparable instruments - a complete sweep up to 13.6 GHz takes just 800 ms. Performance data for digitally modulated signals such as GSM, WCDMA and LTE is available with just a few button presses. They offer sensitivity of (typically) -162 dBm between 8 and 13.6 GHz, and an accuracy of (typically) 1 dB  >8 GHz. The dynamic range, which is normalised to 1 Hz, delivers 145 dB at 1 GHz.

These handheld instruments are optimised for applications in the field. They feature a display that is easy to read even in bright daylight, weigh less than 3 kg and run for up to 4.5 h on a replaceable battery. They come with a wizard for configuring automatic test sequences and the ability to assign functions to buttons.
