5. A screen appears with a setup diagram. (Figure 4-9) This test requires two 6-dB pads. The pads are put on the ANT IN and DUPLEX OUT ports on the Test Set to reduce impedance mismatch error at these ports. A reference level is obtained by connecting a short calibration cable between the pads on the DUPLEX OUT and ANT IN ports. Press k1 (Proceed).

	6.	After the Test Set has finished calibrating, a second diagram
		appears on the screen. Connect the test cable or device to be tested
		between the calibration cable and one of the pads. Press k1
		(Proceed).
	7.	The discrete frequency insertion loss results screen appears with the
		results of the test. The loss is expressed as a negative number in this
		particular test.
	The insertion loss at the specified frequency is displayed twice. The
NOTE
	second display is enlarged for easier reading.
	8.	Press k1 (Proceed) when you are finished with this screen. The
		Discrete Frequency Insertion Loss Test menu appears. If you would

like to repeat the measurement press k1 (Begin Tst). The calibration step will be skipped if none of the parameters were changed. To exit the test press k5 (Return).
