Probe
This oscilloscope supports normal passive probes and active differential probes. It
can automatically identify the type of the probe currently connected and the probe
ratio. Press CH1  Probe to open the probe operation menu.
1. ProbeType
Read the type of the probe currently connected as “Nor-Probe” or “DiffProbe”.
Note that when a 50 Ω “DiffProbe” is used, the
Input Impedance of the
channel is set to “50 Ω” automatically.
 Normal Probe: such as RIGOL RP3500A.
 Differential Probe: such as RIGOL RP7150.
2. Ratio
For some “Nor-Probe”s, the oscilloscope can identify the probe ratio
automatically. If not, press this softkey to select the corresponding probe ratio.
The values available are listed in the table below.
