YDELta?
Query :MARKer:YDELta?
This query returns the current measurement unit difference between Y1 and Y2 if they are
both on and both have the same source. If not, 9.999999E+37 is returned.
Vdelta = value at Y2 – value at Y1
Returned Format [:MARKer:YDELta] <value><NL>
<value> Measurement unit difference between Y1 and Y2.
Example 10 OUTPUT 707;":SYSTEM:HEADER OFF"
20 OUTPUT 707;":MARKER:YDELTA?"
YUNITs
