Detector Outputs
The two detector levels ch
annel ‘A’ & channel ‘B’ are displayed as instantaneous rms values in the left hand
display and smoothed rms in the right hand display. Values in the range 30 to 60 can be expected. Values less
than 30 will cause the gain control system to switch to a x2 high gain setting; values higher than 60 will cause
the gain to be reduced by a factor of 2.
Ch
annel ‘B’ values are additionally adjusted by a software gain stage to equalise channel ‘A’ & channel ‘B’
levels.
