Description
Scientific Atlanta A931 DS3/DS1 Waveform Test Set w/ Travel Case DSX T3 T1
Portable waveform test set for DS3 and DS1 signal analysis. Measures voltage peak-to-peak, symmetry, and pulse width on telecom transmission lines.
Specifications & What's Included
- DS1 input impedance: 100Ω Balanced; DS3 input impedance: 75Ω
- Measurement modes: DSX1, DSX3, DSX1-MON, DSX3-MON, DS3-HI
- Parameters: +Vp, -Vp, +Width, -Width, Symmetry, dBx, Audible
- LED numeric display with PASS/FAIL indicators
- 120V AC recharge input with internal battery operation
- Includes integral metal travel case with latches and carry handle
- Probes not included
Applications
Used for field testing and troubleshooting of DS1 (T1) and DS3 (T3) digital telecom circuits. Compatible with DSX-1 and DSX-3 cross-connect and monitor points. Designed for technicians performing waveform analysis and signal verification on carrier transmission equipment.
Condition: Used
This Scientific Atlanta A931 DS3/DS1 Waveform Test Set has been inspected and is in good used condition. The unit powers on and passes its self-test functions; we were not able to perform further signal-level testing beyond that. The front panel controls, SELECT knob, LED measurement display, and PASS/FAIL indicators all appear intact. The metal travel case is included with functional latches and carry handle — the case exterior shows general wear consistent with field use, and there is a handwritten notation in red marker on the front of the case. Probes are not included. Please view our photo set and contact us if you have any questions.
