NOISE1 (2.5V fs)
When set to NOISE the corresponding DAC connector on the rear panel of the
main console outputs a voltage related to the N1%fs front panel display as
follows:-

NOTE: When NOISE is selected as an output, the Noise Measurement Mode
(Configuration Menu) must be ON. If it is not, a warning message is displayed
which offers the option of turning it on or deselecting NOISE as an analog
output.
RATIO1 (2.5V fs)
When set to RATIO the corresponding DAC connector on the rear panel of the
main console outputs a voltage related to the result of the RATIO calculation,
which is defined as follows:-
 

where X1 output is the X1 channel output as a percentage of the full-scale
sensitivity and ADC 1 is the voltage (expressed in volts) applied to the ADC 1
input connector on the rear panel of the main console. Hence, for example, if the
