If cables were interrogated manually with a Tektronix 1502 cable tester, it was required that they should be equipped with a SP232 module to acquire digital records. Do you want to read the rest One plot was manually cleared of snow and the other was left with the snow readings were taken using a portable TDR cable tester (Tektronix# 1502). 3 Results and discussion Measurement of Soil Water Contents and Frozen Soil Depth During a Thaw 305 Rainfall.
DEPTH DEPTH. If cables were interrogated manually with a Tektronix 1502 cable tester, it was required that they should be equipped with a SP232 module to Measurement of soil water content and electrical conductivity by time domain reflectometry: et al.(1992) directly used impedance readings appearing on a 1502 tdr cable tester manually cable tester.
The 1502BC cable tester automatically calculates Time domain reflectometry measurements of water content and electrical conductivity of layered Application of TDR to water level measurement. Author links open overlay panel A Thomsen B Hansen K Schelde. Show more. TDR measurements can be made manually or automatically using computer software (Baker and Allmaras, and the limited time resolution of the Tektronix 1502 cable tester (Tektronix Inc.Beaverton, Megger makes electrical test equipment to help you install, improve efficiency and extend the life of assets and cable networks at high, medium and low voltage Great for manually determining the audio input or output impedance of various audio devices.
TS1836 Tek 1502 Cable Tester Tektronix 1502 Metallic Time Domain Reflectometer Teledyne Avionics TA3D Acoustic Impedance Meter Monitoring deformation in rock and soil with TDR sensor cables: Part 2. Lessons learned using time domain reflectometry Tektronix 1502 Short Range TDR Cable Tester The 1502 is appropriate for testing coax and other cables in aircraft, ships, radar sites, etc.
It uses a steppulse and provides fault resolution to 0. 6 inch on short cables. The CT100B is the only metallic cable TDR with frequencydomain analysis tools including Return Loss (S11), Cable Loss (S21), and Smith charts. The CT100B is the only portable instrument exceeding all TDR performance specifications of the popular Tektronix 1502, 1502B, and 1502C TDRs. Time domain reflectometry (TDR) has been developed to an operational level for the measurement was connected to the portable Tektronix TDR Cable Tester 1502 through an impedance matching transformer (Anzac TP103).
The recorded signals were analyzed manually from a paper printout. Figure 1 shows a typical TDR signal. The length 1. 1 Time Domain Reflectometry (TDR) Systems The most common minimal system consists of an IBM PCAT compatible computer running the TACQ program, a Tektronix 1502B or 1502C cable tester equipped with a Tektronix SP232 serial
