*RST
//Set the sensor's operation mode to trace
SENSe:FUNCtion "XTIMe:POWer"
//Set the carrier frequency
SENSe:FREQuency 1.8e9
//Set the number of points for the trace measurement
//Using 500 points usually represents a good compromise
//between USB transfer speed and resolution
SENSe:TRACe:POINTs 500
//Set the trace time.It influences the time length of a point since each point
//represents the time period resulting from the trace time divided by the
//number of points
SENSe:TRACe:TIMe 20e-3
//Set the trace offset time to delay the start point
//of the trace measurement for the specified time
