MEASure FREQuency StepSize 1000 Set the step size of the frequency
settings Range: From 0 to 2.7GHz. Unit can be kHz, MHz
and GHz MEAS:FREQ:SS^10MHz
OK
MEASure FREQuency StepSize? 500 Query the step size of frequency
settings MEAS:FREQ:SS?

16=100MHz, 17=200MHz, 18=500MHz,
19=1GHz, 20=2GHz, 21=2.5GHz,22=Full Span. MEAS:SPAN^9 (set the span to
1MHz)
OK
MEASure SPAN FULL 2000 Set span to full span MEAS:SAPN:FULL
OK
MEASure SPAN ZERO 2000 Set span to zero span MEAS:SPAN:ZERO
OK
MEASure SPAN LAST 200 Set span back to last span MEAS:SPAN:LAST
OK
MEASure SPAN? 500 Query SPAN MEAS:SPAN?
OK
MEASure REFLevel 1000 Set reference level +20 dBm to -50 dBm or
127 dBuV to 57 dBuV or
67 dBmV to -3 dBmV or
-12.9 dBm/Hz to -82.9 dBm/Hz @ 3k RBW
-22.9 dBm/Hz to –92.9 dBm/Hz @ 30k RBW
-32.9 dBm/Hz to –102.9 dBm/Hz @ 300k RBW
-44.1 dBm/Hz to –114.1 dBm/Hz @ 4M RBW
The unit has to be identical to the unit in use.
Otherwise the error message will appear. MEAS:REFL^0^dBm
