Tektronix 1503B Opts: no option
The 1503B Metallic Cable Tester that uses time domain reflectometry (TDR), also known as cable radar, to precisely pinpoint faults or changes in impedance in almost any dual-conductor metallic cable. Generates a 1/2 sine pulse, with selectable pulse widths of 2, 10, 100, or 1000 nS. High-resolution 2 nS pulse permits faults as close as 1 foot to be located. Features include direct distance readout- accuracy to better than 1%, intermittent fault monitor mode, high-resolution LCD display with zoom, menu-driven setup, help mode, rugged portability, and calibrated vertical scale. Self tests and internal calibration routines ensure reliability.Option: no option
The rugged 1502B and 1503B cable testers are portable maintenance tools that are simple to operate and can test most dual conductor metallic cable under virtually any condition. The 1500B Series uses TDR to identify and locate cable faults. When the tester 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. The 1500B Series TDRs display impedance changes in the cable as a function of distance. Moving the cursor to the displayed fault produces an on-screen readout of distance to the fault. The 1502B and 1503B support a variety of parameters and other information that can be accessed using menus.
The 1503B MTDR provides high-energy 1/2 sine shaped pulses for testing long cable runs. The 1503B has 2, 10, 100, and 1000 ns pulse widths. Use of the 2 ns pulse width results in 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 1503B is input protected to 400 volts.
The 1503B has a range of 50,000 feet and is the best metallic TDR for general purpose applications. With Option 06, the 1503B can test an active Ethernet bus. Tests are provided for detecting transcievers that ignore the collision signal (babbling transceivers) and transceivers that ignore the carrier sense signal.
