MOVING AVERAGER
MA-1000 Moving Averager
The Moving Averager is used to quantify nerve and muscle electrical activity.
This module comprises an adjustable gain input amplifier, precision full-wave rectifier, and selectable time-constant Moving Averager (Paynter Filter). The larger
the time constant, the greater the smoothing effect of the filter. Standard time constants are 50, 100, and 200mS; the values most often used for EMG and ENG
recording. Other values between 10mS and 500mS are available and can be
installed by the user via convenient plug-in modules.

The RIC-1000 is a versatile instrument for measuring the frequency or interval of pulse-type events. A crystal timebase provides resolution to 100uS. The
count can be updated continuously, or at the end of each interval (sample/hold).
This allows histogram frequency displays or trend lines. The RIC-1000 requires
only the input signal to function; no external gating or reset pulses are required.
The wide-range timebase allows measurements over five decades, or more using
the external clock input.The RIC-1000 makes the perfect companion to the WD1000 Window Discriminator.

WD-1000 Time/Amplitude Window Discriminator
LEVEL A
The window discriminator is used to separate single neuron action potentials
from multi-unit recordings. It can operate as a classic voltage amplitude window
discriminator, or as a time/amplitude discriminator. In the latter mode, the signal
must fall within a voltage and an adjustable time window. This permits separating
similar pulses that differ only in timing. Outputs are available from both window
levels, a data output, and an independent trigger output for synchronizing the oscilloscope trace. These outputs allow simultaneous discrimination of three signals.

General Information
SYSTEM 1000 is a flexible and economical modular instrumentation system. To use the modules described
here, you need a CC-1000 card-cage (six module size) or CC-1000/3 (three module size). Each comes with a universal-input power supply. For benchtop placement, a handsome and rugged molded DeskTop Enclosure is
availalble.
SYSTEM 1000 can be used as a versatile, direct-connect signal conditioning front-end for your data acquisition system. The CC-1000 card-cage has a DB-37 output connector that feeds the module output signals directly
to most data acquisition systems.
Notes:
1. SYSTEM 1000 components are not to be used for Human Life Support Applications.
2. Specifications subject to change without prior notice.

occupies 3U (5.25") height. The card-cage holds up to six instrumentation modules of your choice. DC power
for the modules is introduced via a DIN connector accessible from the rear of the chassis.
Individual channel inputs and outputs are available on the motherboard at the back of the chassis. A D-SUB
37-pin connector also provides all channel outputs, and is directly compatible with the Dataq Instruments
WinDAQ data acquisition system. A handsome molded desktop enclosure (Model DTE-1000) is available as an
