A pocket-sized signal generator and TDR in one convenient package that offers performance in test and measurement equipment
The PerfectPulse signal generator J2151A by Picotest provides a square, 32ps edge pulse. It is available in a portable form that requires only a USB power source with a Time Domain Reflection(TDR) or Time Domain Transmission(TDT).
PCB coupon testing and instrument calibration
The signal generator provides a -500mV, 50 Ohm output signal which is square and is without overshoot or undershoot. The signal can be used for verifying instrument and probe rise/fall times, as well as verifying signal path rise/fall time and undershoot/overshoot.
The inclusion of a 10 GHz power splitter allows the signal generator to be used as a reflectometer for measuring PCB coupons, cable and PCB trace impedance, verifying cable crimps, measuring trace and cable lengths, dielectric constant and much more.
The signal generator is compatible with all 50 Ohm probes for convenient signal injection and its TDR function can be used with an oscilloscope to show the step from an impedance change. Typically drawing 100mA current from USB input, it provides flatness of 3dB at 10.5GHz and 0.1dB (typ) at 2GHz with an output voltage of 0 – 500mV, trimmed to 1% +2.5mV. Along with that, it provides an output impedance of 50 Ohms, trimmed to 1%.
Single button operation allows selection of different operating frequencies with 1kHz, 10kHz, 100kHz, 1 MHz and 10 MHz square wave settings as well as ground and DC output. A 3.5mm connector is used for added performance and reliability.
