J2154A PerfectPulse® Differential TDR

The J2154A is a low-cost single or differential TDR. The internal PerfectPulse signal generator provides a square ~35ps edge pulse in a pocket sized, self-contained package, requiring only a USB power source. The negative 250mV, 50Ω output signal is very square, without overshoot or undershoot, making it perfect for verifying instrument and probe rise/fall times, as well as verifying signal path rise/fall time and
undershoot/overshoot. The internal 10GHz+ power splitter allows the signal generator to be used as a reflectometer (TDR/TDT) for measuring PCB coupons, cable, and PCB trace impedance, verifying cable crimps, measuring trace and cable lengths, dielectric constant, and many other applications. It also allows the measurement of transfer functions, such as oscilloscope probes, and insertion loss (S21).
