Measurement Power Amplifier
Qam
-
The amplifier is DSP controlled, with a very straightforward operation. Included is a white/pink noise signal generator. The internal signal module provides low crest noise signals to be able to reach high power levels from sound sources or electromagnetic shaker. External input of signal is equally possible, with spectral linearisation or without. This can be used for music, RASTI or any other signal
