DMKR STIMULUS For the selected D marker (D marker, fixed D marker, or tracking D marker), sets 
the position in a stimulus value (sweep parameter value).
DMKRPRM <value>
FIXED DMKR VALUE If the fixed D marker is selected, sets the position in the measurement parameter 
value (primary measurement parameter value
1
 of each trace (A and B) if 
COMPLEX Z-Y has been selected as the measurement parameter).
DMKRVAL <value>
FIXED DMKR AUX 
VA L U E
If COMPLEX Z-Y has been selected as the measurement parameter, sets the 
position in the secondary measurement parameter value
2
 of the fixed D marker.
DMKRAUV <value>

1. If COMPLEX has been selected as the display format, the value of the real part of each complex parameter (R or G); if POLAR, 
the absolute value of each complex parameter (|Z| or |Y|).
2. If COMPLEX has been selected as the display format, the value of the imaginary part of each complex parameter (X or B); if 
POLAR, the value of the phase of each complex parameter (q).
