Maximum Voltage At Oscilloscope External Trigger Input - Agilent Technologies 4000 X-Series User Manual

C A U T I O N
CAT I 300 Vrms, 400 Vpk; transient overvoltage 1.6 kVpk
1 M ohm input: For steady-state sinusoidal waveforms derate at 20 dB/decade above
57 kHz to a minimum of 5 Vpk
With N2863A 10:1 probe: CAT I 600 V, CAT II 300 V (DC + peak AC)
With 10073C or 10074C 10:1 probe: CAT I 500 Vpk, CAT II 400 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

The attenuation factor can be set from 0.1:1 to 10000:1 in a 1- 2- 5
sequence.
The probe attenuation factor must be set properly for measurements to
be made correctly.
