In addition to the sensor electronics and the A/D converter, the SCAMP contains two types of analog processing circuits: offset-gain scaling and gradient-gain-filtering.

An offset-gain block is connected between sensor channels and the A/D converter. This block has the effect of allowing the SCAMP's A/D to sample a sub-range of the sensor range under software control. For example, the temperature sensor's electronics has valid output for the range 0 to 30 degrees C. Under software control, the offset and gain block can be programmed such that the A/D's full range occurs over the temperature range of 10 to 15 degrees C, giving 6X resolution. Sub-ranging can also be applied to other channels.

The SCAMP can support up to 8 gradient-gain-filter blocks. These blocks first compute the time derivative of a sensor channel, then amplify the result by a programmable gain of 1 to 256, then filter using a 6-pole anti-alias filter at a fixed frequency of 45 Hz. These circuits can be connected to any channel, but usually are connected only to the fast temperatures. These channels have the effect of eliminating A/D noise since the gradient signals are zero mean and can be amplified significantly.

The paramount design criteria in both the SCAMP's electrical design and mechanical packaging is to obtain a measurement system designed for spectral analysis and having the lowest measurement noise possible.
