3. Front-End
RP7150 active probe provides “Single-end” and “Difference” probe heads. Press
this softkey to select the desired probe head.
4. Probe-Cal
Connect the differential probe to the channel input terminal (such as CH1) of the
oscilloscope correctly, then connect the fast edge signal output from the [Trig
Out/Calibration] connector at the rear panel of the instrument to the probe
and CH2 respectively. At this point, press this softkey and the oscilloscope starts
to calibrate the probe.
Note: If the probe is connected to CH1, CH3 or CH4, the fast edge signal should
be connected to CH2; if the probe is connected to CH2, the fast edge signal
should be connected to CH1.
5. Probe Info
Press this softkey to view information about the probe, such as the manufacturer,
model, serial number and the date of last calibration.
6. Bias Voltage
The oscilloscope provides a bias voltage for differential probes. This bias voltage
is used to adjust the input dynamic range of the probe amplifier to an
appropriate range to ensure accurate measurement of the signal under test.
Press this softkey and use the knob to adjust the bias voltage. The range is from
-12V to +12V.
