Laplace SA1000 Spectrum Analyzer: Specification

The SA1000 analyzer is an exceptionally well-featured, EMC analyzer which is completely controlled from your own PC.

10KHz - 1100MHz frequency range.

High sensitivity. Field strength down to <17dBuV/m when used with the Laplace RF200 broadband antenna.

70dB dynamic range.

Peak. Quasi-peak and average detectors

4 stage input attenuator, 0, 10, 20 and 30 dB

Infinite zoom capability. Tune to any signal anywhere in frequency range.

9KHz and 120KHz I.F. bandwidths (CISPR compliant).

Monitor any signal in Single Frequency mode.

Built-in calibration source to confirm operation and accuracy of analyzer.

An audio demodulator complete with internal loudspeaker is provided so that the user can listen to any signal. This aids both identification of signals, particularly background, and the location of problem emissions. The demodulation technique copes with FM and AM modulation.
