The DSA815 all-digital RF spectrum analyzer from Ohio-based Rigol Technologies Inc. covers a frequency range of 9 kHz to 1.5 GHz.

The $1,295 compact unit offers a typical displayed average noise level (DANL) of -135 dBm, offset phase noise of -80 dBc/Hz at10 kHz and a total amplitude uncertainty of <1.5 dB – suitable for benchtop or field apps in RF and wireless testing and production. Its digital IF design technology lets users measure smaller signals by enabling smaller bandwidth settings, thereby reducing the displayed average noise level.

Standard functions include AM/FM demodulation and a preamplifier plus such optional enhancements as an EMI filter and quasi-peak detector kit, and a 1.5 GHz tracking generator. The $200 Tracking Generator option allows techs to use the device as a VSWR tester with a bridge or to connect to test passive and active RF components. The generator also functions as a static signal source generator from 10 MHz to 1.5 GHz by setting the spectrum analyzer to zero span mode.
