5 Waveform setup
This chapter describes how to connect and set up probes, to adjust the horizontal and
vertical settings, and to control the acquisition.
5.1 Connecting probes and displaying a signal
Risk of instrument damage
Make sure to set the attenuation factor on the instrument according to the probe being
used. Otherwise, the measurement results do not reflect the actual voltage level, and
you might misjudge the actual risk.
The attenuation of the probes that are delivered with the instrument, and the default
attenuation factor of the instrument are 10:1. If you use only the delivered probes and
did not change the attenuation factor, no attenuation adjustment is required.
1. Connect the probes first to the channel inputs, and then to the DUT.
2. Tap the label of the used channel in the bottom line of the display.
3. Tap "Probe".
4. Select the attenuation factor of the probe.
The probe's attenuation factor is indicated on the probe.
No attenuation of passive probes with AC coupling:
If AC coupling is set, the attenuation of passive probes has no effect, and voltage is
applied to the instrument with factor 1:1. Observe the voltage limits, otherwise you
can damage the instrument.
Current measurements:
If you measure current using a shunt resistor as a current sensor, you have to mul-
tiply the V/A-value of the resistor by the attenuation of the probe. For example, if a
