: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.
