probe type and its probe ratio. For detailed technical information of the probes,
please refer to the corresponding Probe User Guide.
Click the CH1 channel status label to open the setting menu of CH1. Then, click
Probe to open the probe menu. If different probes are connected to the oscilloscope,
different information about the probe will be displayed, and you can perform the
different operations on the menu.

Passive Probe

If a passive probe is connected, for example, when RIGOL's RP3500A probe model
is connected to the oscilloscope, click Probe to open the probe menu. Its sub-menus
are grayed out and disabled.
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.

Active Probe

If an active probe is connected, for example, when RIGOL's RP7150 probe model is
connected to the oscilloscope, click Probe to open the probe menu, and you can
operate on the menu item.
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.
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. Click Skew, and use the pop-up numeric keypad or scroll with
the mouse 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
