The computer will respond with the following status information:

Program CMD300 Version 1.nnn

CyberAmp reset to factory defaults.

CYBERAMP 380 (Serial number nnnn) (Microcode version 1.nnn)

These are the factory default settings.

6) Connect the vertical input of your oscilloscope to the Channel 1 output. Set the oscilloscope

controls to 0.2 V/div, 20 ms/div. Issue the following command to the CyberAmp 380 to

generate a test waveform on all channels:

CMD300 TEST ELECTRODE ON

The oscilloscope should display a 1 V

p-p

square wave at 10 Hz (50 ms high, 50 ms low).

Move the BNC cable to channels 2 through 8. The same waveform should be on each

channel.

7) Issue the command:

CMD300 CHANNEL ALL FILTER 6

to set the low-pass filter on all channels to 6 Hertz. The waveform should look almost

sinusoidal and about 0.4 V

p-p

. Verify this for all channels.

8) Issue the command:

CMD300 GAIN 10

to set the gain to x10. The waveform amplitude on each channel should increase ten-fold to

about 4 V

p-p
