SLOPE [n] Output low-pass filter slope (roll-off) control
When the fast analog output mode and noise measurement mode are turned off
(FASTMODE 0 and NOISEMODE 0), the selection is according to the following
table:
n Slope
0 6 dB/octave
1 12 dB/octave
2 18 dB/octave
3 24 dB/octave
When:
a) The fast output filter mode is turned on, or
b) Noise measurement mode is turned ON (NOISEMODE 1)
the selection is according to the following table:
n Slope
0 6 dB/octave
1 12 dB/octave

AXO Auto-Offset
The X and Y channel output offsets are turned on and set to levels giving zero X and
Y channel outputs. Any changes in the input signal then appear as changes about
zero in the outputs.
EX [n] Output expansion control
Expands X and/or Y channel outputs by a factor of 10. This changes the analog
outputs full-scale to ±10% if X or Y selected. The value of n has the following
significance:
n Expand mode
0 Off
1 Expand X
2 Expand Y
3 Expand X and Y
