Spectrum analysers tout sensitivity

Rohde & Schwarz has added two additional models to its R&S FSV family: one up to 13.6 GHz and one up to 30 GHz. The R&S FSV13 and R&S FSV30 combined signal and spectrum analysers stand out because of their sensitivity and large-signal immunity, claims the company.

Especially in the microwave range, sensitivity is an important criterion when selecting a spectrum analyser. For spurious emissions up to 12.75 GHz in wireless communications equipment and systems, as well as in higher frequency ranges as is the case with satellites or military systems, the requirements are very stringent. A low displayed average noise level (DANL) yields measurement results that are more accurate because the signal-to-noise ratio is greater.

Featuring a DANL of less than -148 dBm (1 Hz) at 13 GHz and less than -144 dBm (1 Hz) at 30 GHz as well as a third order intercept of 15 dBm, the R&S FSV can hold its own even alongside high-end instruments. Due to its unique high sweep speed, the R&S FSV performs measurements significantly faster than comparable instruments. This holds true especially when a narrow measurement bandwidth is used.

For users from the aerospace and defence sector, the new R&S FSV models offer a removable hard drive and USB interfaces that can be deactivated. Sensitive data from high-security areas thus remains safe and sound.

Like all instruments of the R&S FSV family, the R&S FSV13 and R&S FSV30 support all current mobile radio and wireless standards by means of software applications. An analysis bandwidth of 40 MHz makes even WLAN 802.11n no problem. Moreover, both models includes a touch screen, an on-screen keyboard and an expanded control panel.

The R&S FSV13 up to 13 GHz and the R&S FSV30 up to 30 GHz are now available from Rohde & Schwarz.
