	Making Measurements	3
	and the analyzer input.
	The coupler should have a high degree of isolation
N O T E
	between the two input ports so the sources do not
	intermodulate.
	2 Set one source (signal generator) to 300 MHz
	and the other source to 301 MHz, for a
	frequency separation of 1 MHz. Set the sources
	equal in amplitude as measured by the analyzer
	(in this example, they are set to –5 dBm).
	3 Set the analyzer center frequency and span:
	• Press [PRESET]. (With Preset Type of Default)
	• Press [FREQ] > {Center Freq} > 300.5 > {MHz}.
	• Press [SPAN] > 5 > {MHz}.
	4 Reduce the RBW until the distortion products
	are visible:
	• Press [BW/SWP] > {RBW}, and reduce the RBW
	using the knob, the arrow keys or the numeric
	keypad.
	5 Move the signal to the reference level:
	• Press [MARKER] > {Peak Search}.
	• Press [MARKER] > {Marker To} > {To Ref}.
	6 Reduce the RBW until the distortion products
	are visible:
	• Press [BW/SWP] > {RBW}, and reduce the RBW
	using the knob, the arrow keys or the numeric
	keypad.
	7 Activate the second marker and place it on the
	peak of the distortion product (beside the test
	signal) using the Next Peak:
	• Press [MARKER] > {Delta}.
	• Press [MARKER] > {Peak Search} > {Next Left
	(Right) PK}.
	8 Measure the other distortion product:
	• Press [MARKER] > {Normal}.
