:SANalyzer:MARKer:DELTa:LEVel <meas cmnd>
:SANalyzer:MARKer:DELTa:LEVel?
These commands set/query the delta marker level measurement. This 
measurement is the level of the normal marker minus the frequency of 
the delta marker in dBm. If the delta marker is higher than normal 
marker, the delta level is positive. If the delta marker is lower than the 
normal marker, the delta level is negative.
The units for this measurement are dB. (There is a percent unit 
available; however, since the spectrum analyzer level is always 
displayed on a logarithmic scale, linear units are inappropriate.)
This measurement utilizes the Number Measurement Syntax, but does 
not use the :METer command.
