Passive Voltage Probes Enable Energy-Efficient Designs

Two additions to the TPP Series of passive voltage probes are well-suited to the needs of engineers tasked with developing more energy-efficient power supplies and power semiconductors. The TPP0850 is the industry’s highest-bandwidth probe (800 MHz) for high-voltage signals (up to 2500 V pk-pk). The probe can be used with switching transistor circuits operating at 1200 VRMS, above the voltage operating range of standard general-purpose probes. It will also be able to accommodate emerging power applications that will require even faster rise-time capabilities. The TPP0502 offers the industry’s highest-bandwidth (500 MHz) and lowest attenuation factor (2X) for making low-voltage measurements such as ripple, a common measurement on the output of power supplies. The low capacitive loading of the TPP0502 means long ground leads have minimal impact on measurement quality. The TPP0850 and TPP0502 probes will be generally available beginning in June. Pricing for the TPP0502 is $585; the TPP0850 costs $750. TEKTRONIX, Beaverton, OR. (800) 833-9200.
