Guralp Systems CMG-DCM build <10,000 - Manual (Page 178)

CMG-EAM (Platinum Firmware)
Perform a sine-wave calibration according to the specified
arguments, which are given as a space-separated list of
key=value pairs:
•
component=[ ALL | Z | N/S | E/W ] - specify
the component(s) to be calibrated
•
duration=m - specify the duration, in minutes, where
m is an integer value. For accurate results, the
duration should be significantly longer than the
response time of the instrument.
•
amplitude=a - specify the amplitude, where a is the
integer percentage of the full output of the cailbration
signal generator. This can normally be given as 100
but should be reduced if clipping is noticed.
•
freq=n - specify the frequency (in integer Hertz) or
period (in integer seconds) of the calibration signal,
according to the setting of...
•
freq_or_period=[ Hz | sec ] - specifies whether
the value associated with freq is interpreted as Hertz or
seconds.
•
adc­command module calib­step arguments
Perform a step calibration according to the specified
arguments, which are given as a space-separated list of
key=value pairs:
•
component=[ ALL | Z | N/S | E/W ] - specify
the component(s) to be calibrated
•
duration=m - specify the duration, in minutes, where
m is an integer value. The calibration signal will first
go negative for this duration, then back to zero for the
same duration, then go positive for this duration, then
return to zero again for the same duration. For
accurate results, the duration should be significantly
longer than the response time of the instrument.
•
amplitude=a - specify the amplitude, where a is the
integer percentage of the full output of the cailbration
signal generator. This can normally be given as 100
but should be reduced if clipping is noticed.
