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:
•
Volts
— for a voltage probe.
•
Amps
— for a current probe.
Measurement results, channel sensitivity, and the trigger level will reflect the
measurement units you have selected.
4
Press the
Probe
softkey; then, turn the entry knob to specify the probe
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.
CAUTION
Maximum voltage at oscilloscope external trigger input
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
