Characteristic Description
n Probe Compensator Output Front-panel BNC connector, requires Probe Cal Deskew Fixture for probe
attachment
Note: During probe calibration only, a relay switches a DC calibration voltage
to this output in place of the 1 kHz square wave. This voltage varies from
--10 V to +10 V with a source impedance less than 1 W and short circuit
current as high as 300 mA.
