CartTime–Domain Reflectometry and Time–Domain Transmissometry Measurement and Analysis
The PicoScope 9211A and 9231A TDR/TDT Oscilloscopes are specially designed for time–domain reflectometry (TDR) and time–domain transmissometry (TDT). It provides a low– cost method of testing cables, connectors, circuit boards and IC packages for unwanted reflections and losses.
The PicoScope 9211A and 9231A work by launching pulses into the device under test using one of their two independently programmable, 100 ps rise–time step generators. They then use their 12 GHz sampling inputs to build up a picture from a sequence of reflected or transmitted pulses. The results can be displayed as volts, ohms or rho against time or distance.
The screenshot below shows the TDR functionality of the PicoScope 9211A being used to analyse a series of via–holes on a PCB spaced 5 mm apart
Remember: the price you pay for your PicoScope Sampling Oscilloscope is the price you pay for everything — we don’t charge you for software features or updates.
Order your PicoScope Sampling Oscilloscope online or from your local Pico distributor.
Note: TDR and TDT measurement and analysis is only available on the PicoScope 9211A and PicoScope 9231A.
