1. There are two cursors a trace cursor and a Spectrogram cursor The trace cursor is the vertical cursor in the spectral display The trace cursor will tell you the frequency and dB level for any signals in the trace currently on screen The Spectrogram cursor is the horizontal cursor in the Spectrogram display This cursor moves up and down through the Spectrogram display and its position determines which trace is currently displayed in the spectral display The Spectrogram cursor will also indicate a timestamp for the currently displayed trace Only one of these cursors is active at atime To make the trace cursor active tap the spectral display with the stylus or your finger Once the trace cursor is active the rotary knob will move the cursor along the trace in the spectral display To make the Spectrogram cursor active tap the Spectrogram display with the stylus or your finger Once the Spectrogram cursor is active the rotary knob will move the cursor up and down the Spectrogram display You can also use the Tab key to move back and forth between the trace cursor and Spectrogram cursor Depending on the number of traces collected there may be more traces than can fit on a single screen Pressing the Down Arrow key or the Up Arrow key will scroll the Spectrogram display to the next or previous screen Use the timestamp information on the Spectrogram cursor or the information in the status bar below the Spectrogram display to help determine your p

3. The Coax In Line Setting allows you to make in line measurements using one of the coax ports as an input and the other as an output The MPP contains a directional coupler between port A and port B Therefore if a signal is originating from the Port A coax input then the signal should appear stronger when the MPP is switched to port A versus port B This technique can be used to determine if a signal is Originating from either the port A or port B side of the coax without having to physically switch the cables on the inputs To use the Coax In Line Input 1 If making an in line measurement on the coax cable from a wall outlet to a television disconnect the coax cable from the back of the television Connect this cable to Coax Port A on the MPP 2 Take the extra length of coax cable included with your OSCOR unit and connect Coax Port B on the MPP to the television Signal will be restored to the television 3 On the OSCOR make sure that the Coax In Line input is selected on the MPP tab On the right side of the tab the options for the selected input will appear 4 Onthe options panel select Port A as the input port Observe any signals present on Port A 84 MULTI PURPOSE PROBE 5 000000 MHz START Gag ee m STOP 2 000000000 GHz 1 002500000 GHz CENTER Tra i PANNI SPAN 1 995000000 GHz Coax In Line Coax Single Ended CCP Carrier Current This mode routes the signal through directional couplers to determ

16. Single Ended mode Because of this any signal connected to one of the ports will be seen at the other port As such Coax Single Ended mode will act very similar to Coax In Line mode however the directionality component is not as strong but there is less overall attenuation Therefore it is best to use Coax In Line mode to determine the directionality of an in line measurement without having to physically switch the inputs and to use Coax Single Ended mode when making single ended measurements 87 MULTI PURPOSE PROBE Because the two coaxial connectors are coupled and because any signal connected to one of the ports will be seen at the other port it is not advisable to connect two different signals to ports A and B at the same time The 100 MHz Baseband Upconvert option mixes the signal with a 100 MHz signal for analyzing baseband see page 93 CCP Carrier Current Probe The CCP Carrier Current input can be used to test for carrier current signals on any pair of conductors less than 250 volts Before testing an unidentified pair of power conductors a voltmeter should be used to measure the voltage across the conductors If this voltage exceeds 250 volts do not test with the MPP To measure carrier current with the MPP 1 Ensure that the battery level of the OSCOR is enough to power the unit Remove the power cord from the AC adapter used to power the OSCOR unit Plug the power cord into the Carrier Curren
