"T" Test oscillators
Format
ATdTO+ Turn on 10 Hz electrode-test oscillator
ATdTO- Turn off 10 Hz electrode-test oscillator
ATdTN+ Turn on notch-filter test
ATdTN- Turn off notch-filter test
where
d = device # (0-9)
Notes
During the notch-filter test, all of the CyberAmp channels are set to unity gain, zero offset, a low-pass
filter frequency of 40 Hz, and the notch filter on. The settings prior to the test are saved and restored
when the notch-filter test is turned off. An approximately sinusoidal signal at the line frequency (50
or 60 Hz depending on country of use) is injected into the inputs of all channels.
IMPORTANT:
After the user has satisfactorily tuned the notch filter, the ATdTN- command must be issued to restore
all settings and stop the line frequency signal.
During Electrode Test, the CyberAmp settings are not changed. When measuring the source
resistance of one input of the differential amplifier, the user is responsible for setting the coupling of
the other input to ground.
"V" Verify internal circuitry
Format
ATdV
where
d = device # (0-9)
Example
The normal response is
RAM OK
EEPROM OK
OFFSETS
1=+00012 Internal offsets = 1.2 mV
2=+00003 Internal offsets = 0.3 mV
3=+00045 Internal offsets = 4.5 mV
4=+00006 Internal offsets = 0.6 mV
5=-00070 Internal offsets = -7.0 mV
6=+00003 Internal offsets = 0.3 mV
7=+00210 Internal offsets = 21.2 mV
8=-09100 Internal offsets = -910.0 mV
Notes
If RAM or EEPROM faults are encountered, the test will stop and display the decimal address of the
faulty memory location.
Note that in this example, channel 8 is suspect because the internal offset is greater than 100 mV.
