Maximum Voltage At Oscilloscope External Trigger Input - Keysight Technologies InfiniiVision 2000 X Series User Manual

CAUTION
300 Vrms, 400 Vpk
1 M ohm input: For steady-state sinusoidal waveforms derate at 20 dB/decade above
57 kHz to a minimum of 5 Vpk
The external trigger input impedance is 1M Ohm. This lets you use passive probes
for general-purpose measurements. The higher impedance minimizes the loading
effect of the oscilloscope on the device under test.
To set the EXT TRIG IN units and probe attenuation:
1 Press the [Mode/Coupling] key in the Trigger section of the front panel.
2 In the Trigger Mode and Coupling Menu, press the External softkey.
3 In the External Trigger Menu, press the Units softkey to select between:
4 Press the Probe softkey; then, turn the entry knob to specify the probe

• Volts — for a voltage probe.
• Amps — for a current probe.
Measurement results, channel sensitivity, and the trigger level will reflect the

attenuation.
The attenuation factor can be set from 0.001:1 to 10000:1 in a 1-2-5 sequence.
The probe attenuation factor must be set properly for measurements to be
made correctly.
