The Keysight N1020A TDR Probe is a useful accessory when making Time Domain Reflectometry measurements on printed circuit boards. If no convenient method of connection is available, such as an SMA launch, then probing is the only viable solution. While most test engineers are very creative in designing and building the appropriate test fixture for each individual application, the TDR Probe is an off-the-shelf-solution. When used in conjunction with the Keysight TDR Oscilloscope Family (Keysight 54750 or Keysight 83480), it provides X, Y and Z positioning in one fluid motion. Its unique 3-D joystick has a 3:1 motion reduction with a fully articulating arm and allows simple positioning in anything from card cages to microstrip-line. If your test tasks get you into some tight spots, the TDR probe gives you a hands-free solution.
