Analysers on higher plane

* Two highly specified spectrum analysers operating at 26.5GHz and 40GHz respectively meet the demand for higher testing frequencies caused by overcrowded airways.

These microwave testers join Rohde & Schwarz’s FSE range of radio frequency analysers, maintaining the same standards of measurement speed, precision, dynamic range and spectral purity, the company says.

It expects these units to have applications beyond digital radio and TV measurement.

* Rugged, compact design makes this high-vacuum gauge suitable for control and measurement functions in harsh industrial environments. The 903 Cold Cathode kit measures vacuum pressures down to 10-10torr. With its analogue output, setpoint and LED indicator, the transducer can be used as a relay gauge, alarm or remote sensor.

* Ideal for measuring vibration on extremely small objects, Endevco’s tiny piezoelectric accelerometer has integral electronics. The 25B is said to be five times smaller than competing brands and weighs just 0.2g. The size and weight cut out adverse mass loading effects.
