1503
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.
