Spectrum Analyser

The MS2683A spectrum analyser has been designed to provide the optimum performance required for the evaluation of third-generation digital mobile radio systems utilising W-CDMA, as well as emerging systems such as Bluetooth and Hyperian2.

The MS2683A covers the frequency range from 9 kHz to 7.8 MHz and is suitable for the development and manufacture of mobile terminals and for parts including amplifiers, mixers, VCOs, etc, as well as in the installations of base stations.

The measurement functions of the product include: a frequency counter; adjacent channel power measurement; occupied frequency bandwidth; average power measurement; channel power measurement; time domain template pass/vail evaluation; and frequency domain mask pass/fail evaluation.

The unit is characterised by a dynamic range of 156 dB typically, a resolution bandwidth of 300 Hz to 20 MHz and a high sweeping speed of 20 times per second.

For adjacent channel power measurements in the case of W-CDMA signals, -68 dB at 5 MHz and -75 dB at 10 MHz is achieved. An optional precision reference oscillator is available with low drift (±5 x 10-10/day).
