Part 6: IEEE 488.2 Command Reference
PRx:OFFSET, PRx:OFST
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.
Command Syntax
<channel>:OFFSET <offset>[V]
<channel>:= {PR1, PR2, PR3, PR4}
V/Div Range Offset Ranges
ADP305 200-499 mV/div (LC series) -40V to 40V
200-499 mV/div (LT series) -100V to 100V
500 mV/div to 9.9 V/div -100V to 100V
10V/div to 99 V/div -1000V to 1000V
100 V/div to 350 V/div -1400V-(4*V/div setting) to 1400V-(4*V/div setting)
ADP300 1 to 9.9 V/div -100V to 100V
10 to 99 V/div -1000V to 1000V
100 V/div to 350 V/div -1400V-(4*V/div setting) to 1400V-(4*V/div setting)
Query Syntax
<channel>:OFST?
Response Format
<channel>:OFST <offset>
Example (GPIB)
The following command sets the offset at the probe tip of the ADP30x differential probe connected to
channel 1 to 5 volts:
