7.5 Probe calibration
The GEN7iB mainframe is provided with a probe calibration output. This output can be
used to calibrate probes used in combination with the Genesis High-speed measure-
ment system.
The probe calibration output drives a calibration signal with the following characteris-
tics:
● ~1 kHz square wave
● 0Vto2Vamplitudewhenusinga1MΩload
● 0Vto1Vamplitudewhenusinga50Ωload
In order to calibrate a probe, connect the probe output to an acquisition card and
set up the acquisition channel in accordance with the probe calibration signals as
described above.
Connect the probe ground wire to the probe calibration ground output pin and the
probe input to the probe calibration signal output pin. See Fig. 7.12.
