Guralp Systems CMG-6TD - Manual (Page 62)

CMG-6TD Configuration with Scream!
5.2.2 Triggering
The Triggering pane is very similar to the corresponding pane of the
Configuration dialogue, although not all options are available since some
require rebooting the digitiser. See section 5.1.3 on page 52 for more
information.
5.2.3 Calibration
You can check that your instrumentation is correctly calibrated by injecting
known signals into the sensor's feedback loop. The Calibration pane allows
you to do this.
Each channel calibrates the corresponding axis of the instrument. Select one
of the Z, N/S and E/W check-boxes to calibrate that axis.
The calibration signal is digitized at a slower rate and returned as a Mux
channel (see section 5.1.4 on page 58) with a stream ID ending MB.
