R&S FSL Spectrum Emission Mask Measurement
1300.2519.12 7.27 E-11
Defining 5 Ranges with all Parameters
In the following example, the Spectrum Emission Mask measurement is configured by defining ranges
and parameters.
REM ************************************************************************
'––––––––– General settings of the instrument ––––––––––––––––––––––––––––––
CALL InstrWrite(analyzer,"*RST") 'Reset instrument
CALL InstrWrite(analyzer,"INIT:CONT OFF") 'Switch to single sweep
CALL InstrWrite(analyzer,":SENSe1:SWEep:MODE ESPectrum")
'Set measurement mode
Rem After preset 3 ranges are available where the middle one is
Rem the reference range for calculating the TX power
CALL InstrWrite(analyzer,":SENSe1:FREQuency:CENTer 2.2GHz")
'Center frequency 2.2 GHz
CALL InstrWrite(analyzer,":SENSe1:DETector1 RMS")
'Set RMS detector
CALL InstrWrite(analyzer,":TRIGger1:SEQuence:SOURce IMMediate")
'Trigger setup
'––––––––– Setting up the gated trigger ––––––––––––––––––––––––––––––––––––
Rem If a free run trigger is not appropriate a gated trigger can
Rem the be set up (just comment in the following lines).
Rem CALL InstrWrite(analyzer,":SENSe1:SWEep:EGATe ON")
Rem Switch on the external gate mode
Rem CALL InstrWrite(analyzer,":SENSe1:SWEep:EGATe:SOURce EXTernal")
Rem Set enternal gate source
Rem CALL InstrWrite(analyzer,":SENSe1:SWEep:EGATe:HOLDoff 0s")
Rem Set delay time to 0 s
Rem CALL InstrWrite(analyzer,":SENSe1:SWEep:EGATe:LENGth 200 US")
Rem Set time interval
'––––––––– Setting the span ––––––––––––––––––––––––––––––––––––––––––––––––
CALL InstrWrite(analyzer,":SENSe1:FREQuency:SPAN 8 MHZ")
'Set the span to 8 MHz
'––––––––– Inserting new ranges ––––––––––––––––––––––––––––––––––––––––––––
Rem Enlarge number of ranges to 5 by adding one at the end
Rem and one at the beginnig. This ensures that the reference range
Rem remains in the middle
CALL InstrWrite(analyzer,":SENSe1:ESPectrum:RANGe2:INSert AFTer")
'Insert a range after range 2
CALL InstrWrite(analyzer,":SENSe1:ESPectrum:RANGe1:INSert BEFore")
'Insert a range before range 1
'––––––––– Defining the limit check for all ranges –––––––––––––––––––––––––
CALL InstrWrite(analyzer,":SENSe1:ESPectrum:RANGe:LIMit:STATe AND")
'Set check for absolute and
'relative limit
