WARNING. Dang
erous voltages will be present on the calibration generator output terminals and connection cables. Always
verify that the generator is in the standby mode before y ou make any connections to the generator.
1. Verify that the generator output is off.
2. Connect both of the probe inputs to the red (+) banana connector on the front output of the generator. Use a
BNC-banana adapter i
f necessary.
3. Set the output of the generator to 297 V
p-p
(105 Vrms) @100 kHz.

Probe Generator output
Model Range Voltage (p-p) Frequency
THDP0100 600 V 297 V 100 kHz
THDP0200 150 V 297 V 100 kHz
TMDP0200 75 V 297 V 100 kHz
4. Set the osci
lloscope horizontal to 10 μs/div.
5. Set the prob
e bandwidth to full and the attenuation to the lower range of the probe.
6. Enable the g
enerator output. Adjust the oscilloscope vertical to display the signal.
