Example: Performing a Highly Accurate Frequency Measurement Using the Sig-
nal Count Marker
This example demonstrates how to determine highly accurate frequency values using
signal count markers in a basic spectrum measurement in a remote environment. It
assumes that the basic frequency sweep described in
Chapter 11.6.17, "Programming
Example: Performing a Basic Frequency Sweep" , on page 747 has been performed
and thus does not begin by presetting the instrument.
//------------- Configuring the signal count marker -------------------
CALC:MARK1 ON
//Activates marker1
CALC:MARK1:COUN ON
//Switches on the frequency counter for marker 1.
CALC:MARK1:COUN:RES 1kHz
//Sets the resolution of the frequency counter to 1kHz
//------- Performing the measurement -------------------------
INIT;*WAI
//Performs a measurement and waits for it to end
//---------------Retrieving Results-------------
CALC:MARK1:COUN:FREQ?
//Returns the signal counter value as the precise marker frequency.
