The Tektronix 1503 is a sinusoidal TDR cable tester with a similar design to the 1502B/C step-pulse TDRs.

The 1503 transmits a 5 V half-sine pulse of selectable duration, allowing an operator to examine up to 50,000 feet of cable.

Standard accessories in the 1503C (and others?) include SLA battery and which makes it quite heavy. The YT-1 Chart Recorder is also heavily constructed.

Key Specifications

please add

Test Signal - Step rise.
Amplitude - 300 mV nominal into 50 Ω load.
System Risetime - 10% to 90%, 200 ps (1.15 in./2.92 cm).
Output Impedance - 50 Ω.
Electrostatic Discharge Protection - 1 kV/500 pF/1 kΩ.
Maximum Range - 2,000 ft. (625 m).
Distance Readout Resolution - 0.05 in. (0.12 cm).
Noise Filtering - 1 to 128 averages.
Vertical Scale - 0.5 mp/div to 500 mp/div.
Vertical Accuracy - ±3% full scale.
Distance/Division - 0.1 ft./div to 200 ft./div (0.025 m/div to 50 m/div).
Horizontal Accuracy - 1.6 inches (0.041 m) or ±1% of measured distance plus uncertainty in Vp, whichever is greater (for Vp = 0.66 and Dist/Div = 1 ft.)

When testing 50 Ω cable with a Vp of 0.66, the 1502C allows the determination of 0.5 Ω cable faults. Multiple faults can be measured as close as 0.8 inch. The 1502C measures 50 Ω impedance.

-The 1500C Series is designed to quickly and easily locate opens, shorts, crimps, and other defects in metallic cables. The 1502C can measure up to 2,000 feet (625 meters).
-Using a process similar to radar, the 1500C Series transmits electrical pulses down the cable under test. Impedance changes in the cable reflect some of the pulse energy back to the MTDR. The reflections are displayed on a backlit, HyperTwist, high-contrast nematic LCD display. The characteristics of the displayed trace allow the user to determine the nature of the cable fault.
 When testing 50 Ω cable with a Vp of 0.66, the 1502C allows the determination of 0.5 Ω cable faults. Multiple faults can be measured as close as 0.8 inch. The 1502C measures 50 Ω impedance.
