The ESP300 series of spectrometers include two digitizers: one high resolution
ADC included in the signal channel (reference ER023M) and a fast one
in the computer (reference ESP1600-1072 or ESP1600-1070).

The input voltage ranges depend on the digitizer. Could you please let us
know the one you are using? Are you using the ADC to digitize the signal
from the Microwave Bridge or from another source?

Via FAX, we also forwared additional information as well as answers to
other questions you had.

Sincerely,
