Evaluating the Results
The commands required to control the demodulation of signals at the marker position
are described in
Chapter 11.8.8.14, "Marker Demodulation"
11.6.14.8
Programming Example: EMI Measurement
This example demonstrates how to detect electromagnetic interferences (EMI) in a
remote environment.
//----------- Preparing the measurement ------------
//Reset the instrument
*RST
//Define the span to be analyzed
FREQ:STAR 150kHz
FREQ:STOP 1GHz
//Configure two traces, one with peak detector, one with average detector
DISP:TRAC1 ON
DISP:TRAC2 ON
DET1 POS
DET2 AVER
//----------- Configuring the measurement ------------
//Select EMI measurement
CALC:MARK:FUNC:FME:STAT ON
//Configure CISPR filter and RBW
BAND:TYPE CISP
BAND:RES 1MHz
//Define the dwell time
CALC:MARK:FUNC:FME:DWEL 1ms
//Configure an auto peak search
CALC:MARK:FUNC:FME:PEAK:AUTO ON
//Configure a logarithmic frequency scaling
DISP:TRAC:X:SPAC LOG
//Configure marker demodulation for marker 1
CALC:MARK:FUNC:DEM ON
//Increase the number of sweep points
SWE:POIN 200000
//Set the unit to V
CALC:UNIT:POW V
//----------- Configuring EMI markers ---------------
