Signal Output
Signal attenuation
Thus, signal output level at the +1 mV analog output may be set
separately from that at the +1 V output.
Table 5•2gives values permitted for either function, and the output
affected.
Table 5-2.

the largest peaks of interest do not exceed 1 volt. Attenuation functions
at the integrating device or computer are then used to ensure that plotted
peaks remain on scale.
RANGE 2

such that the highest possible value for the portion does not exceed
maximum output voltage allowed for the given output (+1 mV or +1 V).
