Part 6: IEEE 488.2 Command Reference
VERT_POSITION, VPOS
Description
The VERT_POSITION command adjusts the vertical position of the specified trace on the screen. It does
not affect the original offset value obtained at acquisition time.
The VERT_POSITION? query returns the current vertical position of the specified trace.
Note: The VPOS command and query can only be applied to math function and memory traces. It
does not apply to channel inputs.
Command Syntax
<trace>:VERT_POSITION <display_offset>
<trace>:= F1 to Fn, M1 to Mn, TA to TD
<display_offset>:= -5900 to +5900 DIV
Note: TA through TD are for backward compatibility. Although accepted, they are not returned by
queries.
The unit DIV is optional. The limits depend on the current magnification factor, the number of grids on the
display, and the initial position of the trace.
Query Syntax
<trace>:VERT_POSITION?
Response Format
<trace>:VERT_POSITION <display_offset>
Example (GPIB)
The following instruction shifts trace F1 upwards by +3 divisions relative to the position at the time of
acquisition:
CMD$="F1:VPOS 3DIV": CALL IBWRT(SCOPE%,CMD$)
