Probe
This oscilloscope supports normal passive probe and active differential probe and 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 RP3500.
 Differential Probe: such as RIGOL RP7150.
2. Ratio
For some “Nor-Probe”, 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.
