N1021B Differential Time-Domain Reflectometry and Time-Domain Transmission Probe Kit Details
The N1021B is an ergonomically designed handheld probe to interface TDR/TDT modules to printed circuit boards (PCBs) and components that lack common coaxial high-frequency connectors. The built-in wheel adjusts the pitch between the differential tips to make good contact with pads or access points spaced from closed to typical IC pins (2.54 mm).
Engineers working on high-speed differential electrical channels can analyze where the device under test (DUT) causes reflections that unfavorably affect the signal integrity (SI) of their designs. Manufacturers of printed circuit boards (PCB) can control process consistency from batch to batch, and/or locate the position of shorts, opens, or other flaws.
The N1021B probe is used in conjunction with the DCA-X Wideband Oscilloscope Mainframe, the 54754A Differential and Single-ended TDR-TDT Module, and the N1055A35/50 GHz 2/4 Port TDR/TDT Remote Sampling Head. The N1021B probe launches small electrical steps in the DUT (device under test) and/or receives the response, which is processed and displayed in the time domain or as S-parameters (SDD11, SDD22, SDD21, or SDD22). Time-domain measurements can display the reflected voltages or observed impedances versus time or distance. S-parameter measurements include magnitude, phase, and group delay.
