Sets or queries the position of Cursor B when the measurement range is the "cursor area".
Parameter
Name Type Range Default
<cbx> Integer 6 to 697 400
Remarks
 The position of the cursor is defined by the pixel coordinate of the screen. The range of the pixel
coordinate on the screen horizontally is from 0 to 699 (from left to right).
 The actual range of <cbx> is related to the position of Cursor A (refer to the :MEASure:CREGion:CAX

<chanB> Discrete {CHANnel1|CHANnel2|CHANnel3|CHANnel4} --
Remarks
 Before making measurements, turn on the channels to be measured.
 When [<chanA>,<chanB>] is omitted, this command will be applied to Source A (refer to
the :MEASure:SETup:DSA command) and Source B (refer to the :MEASure:SETup:DSB command) of
delay measurement currently set by default.
