Basic frequency sweep measurement for marker function examples
Since markers can only be placed on an existing trace, the following example provides
a simple frequency sweep measurement to be used as a basis for the subsequent
marker function scripts.
//-------------- Configuring the basic frequency sweep -------------
*RST
//Resets the instrument
INIT:CONT OFF
//Selects single sweep mode.
FREQ:CENT 100MHz
//Defines the center frequency
FREQ:SPAN 200MHz
//Sets the span to 100 MHz on either side of the center frequency.
DISP:TRAC1:Y:RLEV 0dBm
//Sets the reference level to 0 dBm.
//------- Performing the measurement -------------------------
INIT;*WAI
//Performs a measurement and waits for it to end
Example: using a fixed reference marker
This example demonstrates how to configure and use reference markers in a basic
spectrum measurement in a remote environment. It assumes that the basic frequency
sweep described in
"Basic frequency sweep measurement for marker function exam-
ples" on page 1224 has been performed and thus does not begin by presetting the
instrument.
//-----------Configuring the reference marker ------------
//Activate a fixed reference marker. It is set to the current maximum of trace 1.
CALC:DELT:FUNC:FIX ON
//Set the reference frequency to 128 MHz.
CALC:DELT:FUNC:FIX:RPO:X 128 MHZ
//Set the reference level to +30 dBm.
CALC:DELT:FUNC:FIX:RPO:Y 30 DBM
//Use the fixed reference marker as a reference for deltamarker 2
