The 2395 26.5GHz spectrum analyzer of IFR Systems Inc. increases the bandwidth of the company's 2394/2399A spectrum analyzer series and is targeted for applications such as microwave point-to-point radio links and tower-mounted transmitters.

Measuring 350-by-185-by-395mm, the device weighs 12kg and features a 6.4-inch LCD. It has a fast processor and large memory, allowing the storage of up to 1,000 screen traces and 2,000 operational states. It has a 50 ohm input that accepts signal between 30dBm and -110dBm, while providing protection up to 50Vdc.

Similar to the 2394 13GHz spectrum analyzer, the 2395 also includes a comprehensive marker system that allows as many as nine markers to be displayed at any one time, together with a marker table showing the frequency and level of each marker selected. This feature allows multiple signals to be evaluated simultaneously.

In addition to Normal Markers, the device provides delta markers, peak search, peak track, 1/delta, marker track, marker to center, and marker to reference capability. It also allows semi-automated measurements of adjacent channel power, channel power, occupied bandwidth, emission bandwidth, X dB down, and harmonic distortion. Also included is an auto tune function, allowing an unknown signal to be captured quickly and displayed on the screen.

The 2395 operates from 9kHz to 26.5kHz and offers resolution of 300Hz to 3MHz. Sweep speed is between 5ms to 1,000s. It also features IEEE 488.1 and 488.2, as well as RS-232 interfaces.
