TPR1000 and TPR4000 Datasheet

Why use a power-rail probe?

The added functionality, higher density, and faster switching speeds of

modern electronic products drive the need for lower supply voltages.

Designers need to zoom-in on power rails to look for high-frequency

intruder signals, measure ripple and analyze coupling effects with tighter

tolerances. Oscilloscopes often don't have enough offset to shift the noise

and ripple on DC rails to the center of the screen to make the needed

measurements.

The TPR1000 and TPR4000 probes provide a low-noise measurement

solution (oscilloscope and probe), which is critical to not confuse the noise

of the oscilloscope and probe with the noise and ripple of the DC supply

being measured. The higher input impedance in the probes minimize the

oscilloscope loading effect on DC rails (50 kΩ at DC). The probes provide

higher bandwidth to see more signal content (harmonics, faster ripples,

etc.) on DC rails that could affect data signals, clocks, etc.

The TPR1000 and TPR4000 provide a best-in-class integrity solution for

power integrity and validation engineers in the high speed (μP), low power

(mobile) and switched-mode power supply markets. The probes are

designed to offer the lowest noise with high bandwidth at 60 V offset,

flexible connectivity options to cover customers challenges, and software

packages to cover the digital power management market.

Connectivity using probe accessories

The available probe accessories provide solutions for reliable and

repeatable power rail measurements.
