Rise Time Test
Set the Calibrator output to give a fast rise time. Attach the BNC T piece to the calibrator output. Attach the
●
50Ω Termination to one arm of the T piece, attach the BNC Male to binding posts adapter to the other arm
of the T piece. Plug the probe measurement leads into the binding posts.
Set the Calibrator output voltage to a suitable level to make a measurement on the probe, but not high
●
enough to damage the
Vrms applied.
Connect the probe output to the oscilloscope and measure the rise time of each voltage range according
●
to the measurement table. Note: An oscilloscope of sufficient bandwidth is required to make this
measurement, see recommended oscilloscope bandwidth in the table below.
After measuring remove the probe from the DUT and power off the probe by removing the USB power
●
supply.

DC Common Mode Ratio Test
Set the T3HVD probe to its lower voltage range and connect the probe inputs to the DC voltage source or
●
calibrator.
Set the multimeter to DC Volts, connect the multimeter cables together, then auto-zero the multimeter.
●
Connect the T3HVD probe output BNC to the multimeter using the BNC male to binding posts adapter and
●
the multimeter cables.
Set the DC voltage source or calibrator output to 500V DC. Enable the DC voltage source or
●
calibrator output. Record the probe output voltage, as measured by the multimeter, in the table
below.
Disable the DC voltage source or calibrator output and remove the probe.

not turn on the 500 V DC output until the completion of all test connections. Turn off the 500 V DC
output before disconnecting the probe.
