Chapter 2 To Set the Vertical System RIGOL
MSO7000/DS7000 User's Guide 2-9
Passive Probe
If a passive probe is connected, for example, when RIGOL's RP3500A probe model
is connected to the oscilloscope, press Probe to open the probe menu. Its
sub-menus are grayed out and disabled.
Active Probe
If an active probe is connected, for example, when RIGOL's RP7150 probe model is
connected to the oscilloscope, press Probe to open the probe menu, and you can
operate on the menu item.
Probe Delay
To avoid measurement result errors arising from the transmission delay of the
probe cable, the oscilloscope provides the probe delay adjustment function for
the active probe. Press Skew, and then rotate the multifunction knob or
use the numeric keypad to set the probe delay time.
Bias Voltage
The oscilloscope provides the bias voltage adjustment function for active probes.
This function is used to adjust the signal under test that exceeds the input
dynamic range of the probe amplifier to an appropriate range to ensure the
integrity of the signal under test. Press Bias, rotate the multifunction knob
or use the numeric keypad to set the DC bias voltage.
Probe Information
Press About to view information about the probe currently connected, such as
the manufacturer, model, serial number, and the last calibration date.
Probe Calibration
Press Calibration to start zero calibration automatically for the probe.
Tip
For some of the ordinary passive probes, the oscilloscope can recognize their
probe ratio automatically. If not recognized, please refer to "Probe Ratio" to set
the probe ratio.
Tip
When a 50 Ω active probe is connected, the input impedance (refer to "Input
Impedance") of the channel will be automatically set to "50 Ω".
For the active probe, the oscilloscope can recognize the probe ratio
automatically. If the currently connected probe supports a variety of probe
ratios, please refer to "Probe Ratio" to set the probe ratio.
