What Is TDR Measurement?

Time Domain Reflectometry (TDR) is a technique used to locate faults, measure impedance, and characterize signal integrity along cables and transmission lines. A fast-edge pulse is launched into the line, and reflections are analyzed to reveal discontinuities, shorts, or impedance mismatches. This pulse generator's 150 ps rise time provides the temporal resolution needed for high-precision TDR analysis.

Oscilloscope Bandwidth Verification

To accurately assess an oscilloscope's bandwidth, you need a signal with a rise time significantly faster than the scope itself. With a 150 ps rising edge, this generator is suitable for testing oscilloscopes up to and beyond 1 GHz bandwidth — giving you confidence in your instrument's specifications.

Frequently Asked Questions

Q: What is a fast edge pulse generator used for in electronics testing?

A: A fast edge pulse generator produces signals with an extremely short rise time — in this case, 150 picoseconds. It is primarily used to verify and measure the bandwidth of oscilloscopes, as well as to perform Time Domain Reflectometry (TDR) measurements for characterizing cables, PCB traces, and connectors in terms of impedance and signal integrity.

Q: What oscilloscope bandwidth can this 150 ps pulse generator test?

A: As a general guideline, a rise time of 150 ps corresponds to a bandwidth of approximately 2.3 GHz (using the 0.35/rise time rule). This makes the generator suitable for testing and verifying oscilloscopes with bandwidths ranging from hundreds of MHz up to several GHz.

Q: How does TDR measurement work with this pulse generator?

A: The pulse generator sends a fast-edge signal into the device under test (DUT) — such as a cable or transmission line. Reflections caused by impedance mismatches, opens, or shorts travel back and are captured by the oscilloscope. By analyzing the timing and amplitude of these reflections, you can pinpoint fault locations and characterize the electrical properties of the line.

Q: What connector type does this pulse generator use?

A: Please refer to the product images for connector details. For compatibility questions specific to your setup, we recommend reviewing the images carefully or contacting us directly before purchase.
