Description
DESCRIPTION
The NL530 Signal Conditioner Module from Digitimer is a single width module designed to give gain and offset set-up controls when interfacing signals to the analog-to-digital converters (ADCs) of PCs. The NL530 module contains four channels each with independently adjustable filter settings and front panel gain and offset presets.
There is also a master ADC offset control to allow unipolar ADCs to be used with bipolar signals. As ADC boards have a precise input range (outside of which damage may occur) the NL530 Signal Conditioner Module features on-board preset controls to set all channels to ‘CLIP’ (or limit) at independently set positive and negative (or zero) levels.

Specifications common to all channels
* Clip limits: | Positive: +4V to +11V min. Negative: -11V min to 0V |
* ADC Offset: Zero (0 volts) or +2.5V
ø = screwdriver adjustable single turn front panel preset
* = on-board controls
Gains may be increased by a factor of 10 via a factory modification (SM402). This modification is recommended when the NL530 is used to further amplify output signals from our miniature 8 channel D168 telemetry preamplifier headstage.
