Maximum Voltage At 2-Channel Oscilloscope External Trigger Input - Agilent Technologies 7000B Series User Manual

4 Triggering
Range
in current mode, the range is fixed at 1.0 Amps. Range is automatically
scaled according to the probe's attenuation factor.

Maximum voltage at 2-channel oscilloscope external trigger input

C A U T I O N
CAT I 300 Vrms, 400 Vpk; transient overvoltage 1.6 kVpk
CAT II 100 Vrms, 400 Vpk
50 input: 5 Vrms
Input protection is enabled in 50 mode and the 50 load will disconnect if greater than 5
Vrms is detected. However the inputs could still be damaged, depending on the time
constant of the signal. The 50 input protection only functions when the oscilloscope is
powered on.
1 M ohm input, 100 MHz models:
For steady-state sinusoidal waveforms derate at 20 dB/decade above 200 kHz to a
minimum of 10 Vpk
1 M ohm input, 350 MHz, 500 MHz, 1 GHz models:
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
Input Impedance
trigger input impedance. The impedance can be set to either 1M Ohm or
50 Ohm by pressing the Imped softkey.
• 50 Ohm — matches 50- ohm cables commonly used in making high
• 1M Ohm — is for use with many passive probes and for general- purpose
Probe Units

for a current probe. Measurement results, channel sensitivity, and trigger
level will reflect the measurement units you have selected.

The input voltage range can be set to 1.0 Volts or 8.0 Volts. When
The 2- channel oscilloscopes have selectable external
frequency measurements. This impedance matching gives you the most
accurate measurements since reflections are minimized along the signal
path.
measurements. The higher impedance minimizes the loading effect of
the oscilloscope on the device under test.
