Signal Conditioning and Signal Filtering Modules here at Digitimer deliver on a per-module basis. Our Conditioner Modules include filters, amplifiers and attenuators. Signal conditioning is the handling and changing of a signal and how it is prepared for what will be the next step in the way it is processed.
Further information regarding each of the NeuroLog signal conditioning modules that we stock can be found by clicking the more details tab of each product.
To discuss our Signal Filtering or Conditioner Modules in more detail you can email our team at firstname.lastname@example.org or alternatively you can go to our contact page where you will find more ways you can get in touch with Digitimer experts. We are happy to discuss any of the products we have on offer.
NL125/6 – Band-Pass Filter
The NL125/6 band-pass filter module employs two active sections to control the high and low pass characteristics. The low frequency cutoff point can be set continuously from 0.5Hz to 5kHz with a single turn potentiometer, in four switched ranges. Similarly the high frequency cutoff can be set continuously from 5Hz to 50kHz in four switched ranges. DC and WB (wide band) switch positions by-pass the lower and upper filter sections, respectively.
NL134/5/6 – Four Channel Low Pass Filters
The NL134/5/6 FILTERS are 4-channel, second order (two-pole) low-pass with mains frequency Notch reject (NL135/6 only) filter modules. They are ideal partners for the NL820 Isolated Amplifier system. The filter settings have been selected for most electrophysiological protocols but other frequencies can be factory set to order. A rotary switch selects the 14 frequency settings giving repeatability over a wide range….
NL143 – Three Channel Difference Amplifier
The NL143 is a 3-channel difference, or differential, amplifier with 4-channels of input. Internal selection allows the difference between any of the four input channels to be made. Internal preset controls (finger operated) allow an offset to be nulled or added as required. High input protection allows for signals coming from units that are not part of the NeuroLog System. This module allows the difference between two signals….
NL144 – Four Channel High Pass Filter
The NL144 is a 4-channel, second order (two-pole) high pass filter which complements the NL134/5/6 mentioned above. when used with the NL820A isolator, these module provide a compact solution to 4 channel high and low pass filtering.
NL530 – Signal Conditioner
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 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)
