FSH6 spectrum analyser

Rohde & Schwarz has expanded the frequency range of its handheld spectrum analyser to 6 GHz, making it suitable for all WLAN 802.11a applications as well as for general laboratory applications in higher frequency ranges.

The FSH6 can also be tuned using channel numbers instead of frequencies and facilitates operation for many users from mobile radio and broadcasting.

The handheld instrument is available in two versions with a frequency range from 100 kHz to 6 GHz. The optional integrated tracking generator makes the instrument suitable for scalar and vector network analysis, distance-to-fault measurements and one-port cable loss measurements.

In many cases, however, it can also be used without a tracking generator for installing, optimising and servicing WLAN 802.11a networks or in general laboratory applications. It tests the frequency and level of local oscillators in mobile radio telephones between 3.4 and 3.9 GHz and is suitable for use in repair stations.

The device includes an adjustable preamplifier which enables sensitive measurements over the entire frequency range. If the preamplifier is switched on, the displayed average noise level of the instrument is typically -135 dBm at 100 Hz bandwidth.

With a guaranteed measurement accuracy of greater than 1.5 dB (and typical 0.5 dB), the specifications come close to those of a high-end desktop instrument.

With vector transmission measurements, the FSH6 achieves a dynamic range of typical 90 dB. This best-of-class value makes it suitable even for critical antenna isolation measurements on base stations.
