: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.
