EMG Coupler (model 573)
for obtaining the envelope curves from muscle potentials.
Max. sensitivity 10µV/cm, adjustable continuously and in stages x
50 / x 500 / x 5000
Input can be switched off for functional testing.
Calibration button for 0.1 / 0.3/ 1 mV.
Filter for low cut off: 2 / 20 / 50 Hz
Filter for high cut off: 0.5/ 1 / 2 kHz
Filter for envelope curve: 5 / 25 / 125 Hz
Spikes can continuously be monitored by an oscilloscope connected to the
direct input of the recorder. (In this case the input works as an output!)

AC: 50 mV
DC: 300 mV
Input common mode voltage: ±3 V
CMMR: better than 10 000:1
Input resistance: higher than 100 MOhm
