ADP300/305 Probe
16
ADP30X-OM-E Rev B
Probe Offset
PRx:OFFSET, PRx:OFST
Command/Query
Description When an ADP30X probe is connected to a channel, the OFFSET
command sets the probe offset value.
The maximum range and resolution is determined by the V/DIV setting. If
an out-of-range value is entered, the differential probe will set the offset
to the closest valid value, and the VAB bit (bit 2) in the STB register will
be set.
The OFFSET? query returns the offset voltage of the differential probe
connected to the specified channel.

Example The following command sets the offset at the probe tip of the ADP30X
differential probe connected to 1 to 5 volts:
