NOTE This test measures the loss of a cable or device at a specified frequency This test is the most accurate method for measuring insertion loss In the menu for this test you can enter the discrete frequency and signal level at which the measurement will be made 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 Next the test cable or device is added between the calibration cable and one of the pads and a measurement is made of the addition loss from the reference level The insertion loss at the specified frequency is displayed on the screen Theinsertion loss at the specified frequency is displayed twice The second display is enlarged for easier reading Swept Insertion Loss Chapter 3 This test measures the loss of a cable or device by sweeping it over the specified frequency range In the menu for this test you can enter the frequency range over which the cable is to be swept 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 an ANT IN ports Next the test cable or device is added between the calib
