Is there an attenuator built-in on RIGOL's DSA1030?
Last Updated: 07/11/2013
Yes, but you should still take care never to exceed the DSA1030's max input power or voltage (+30dBm or 1000mW and 50VDC abs. max - pulsed waveforms can easily exceed this e.g. direct from a LISN). The attenuator is variable to give relative 0-30dB and whilst it does not increase the permissible power, it is designed to allow the instrument to optimise its dynamic range, enabling it to measure louder signals without distortion and maintaining good accuracy.
