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 of each independent channel
| Input: Abs. Max. Input: Input Impedance: * Gain: ø Variable Gain: ø Offset control: |
Front panel Lemo socket ±100V 20k ohms Off; x0.1; x0.2; x0.5; x1; x2; x5; x10 x1 (cal.) to x2.5 (nom.) ±1V or ±5V |
* Offset range: ±1V or ±5V

100Hz, 1kHz, 10kHz, none DC – 100kHz less than -56dB between channels Front Panel Lemo socket ±11V minimum <5 ohms (for up to 10mA load) |
Output = (Input * Gain) + (ADC + Variable) Offsets
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.
