4.6 Location of a signal with the SPECTRUM ANALYZER Connect the cable with the input signal to the RF IN input connector. Press the SPECTRUM key. The spectrum of the signal is displayed. Adjust the SPAN (recommended value for a terrestrial signal 50 MHz and for a satellite signal 100 MHz). The current value of the SPAN is at the right bottom of the screen. Find the frequency of the signal by moving the JOYSTICK left or right to move sweeping the entire band. If you know the channel change the tuning by frequency to tuning by channel. The channel mode allows you to navigate from channel to channel, using the selected channel plan. When the channel is locked information appears at the bottom left of the screen. The equipment automatically detects transmission parameters of the signal and makes the corresponding measurements. August 2012 4-35
