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. | 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 | YT-1 Chart Recorder]] is also heavily constructed. | |||

* 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. | |||
