    The portable, rugged 1502C and 1503C TDR Cable Testers are portable maintenance tools that are simple to operate and will test most dual conductor metallic cables under virtually any condition.? A high-contrast LCD, waveform storage, and PC controllability make the 1502C and 1503C TDRs well-suited for a wide range of testing applications.? The 1500C Series uses TDR to identify and locate cable faults.? When the instrument is connected to the line to be tested it sends out electrical pulses that are reflected back to the tester by impedance changes in the cable as a function of distance.? Moving the cursor to the displayed fault produces an onscreen readout of distance to the fault.

    1503C General Purpose MDTR

    The 1503C MTDR generates high-energy, 1/2-sine shaped pulses for testing long cable runs.? The 1503C has 2, 10, 100 and 1000 nanosecond pulse widths.? Use of the 2 ns pulse width permits determination of multiple faults as close together as one foot.? Cable impedances of 50, 75, 93, and 125 ohms are selectable at the front panel.? The 1503C is input protected to 400 volts.
    The 1503C has a range of up to 50,000 feet and is the best metallic TDR for general purpose applications.

    1503C Option 06 for Ethernet Testing

    The 1503C with Option 06 allows TDR testing of an active Ethernet bus.? Tests are provided for detecting transceivers that ignore the collusion signal (babbling transceivers) and transceivers that ignore the carrier signal.
