Mixed Signal Oscilloscopes Offer Low System Noise



Tektronix is introducing the TPR1000 and TPR4000 power rail probes that combine with the 12-bit 5 or 6 Series MSO mixed signal oscilloscopes to offer the lowest system noise of any power-rail measurement solution available in the market today. The new probes are backed by a complete set of connectors for small, difficult-to-access test points helping to reduce connection frustration

The new TPR1000 and TRP4000 power rail probes combined with a 5 or 6 Series MSO, offer the lowest system noise on the market.

Several factors conspire to make accurate power rail measurements challenging:

  • Noise from the oscilloscope and probe is indistinguishable from the noise and ripple of your DC supply
  • Oscilloscopes often don’t have enough offset to shift DC rails onto the display
  • Low-impedance probes can load down a power rail – changing the way it performs.  But high-impedance, high-attenuation probes tend to be noisy.  The perfect probe would present high resistance to DC but 50 ohms for AC
  • Probes may not have sufficient bandwidth to see GHz noise that can affect high-speed drivers

The new TPR1000 and TPR4000 power rail probes address each of these concerns. The ultra-low noise contribution of the probes helps you measure the noise on your DUT – well below a millivolt.  The probes offer up to 60 V offset, 1 V dynamic range and up to 4 GHz of bandwidth.

They offer connection options to cover most scenarios:

  • Various solder-in tips offer reliable access to hard to reach, sensitive signals with optimal signal resolution at up to 4 GHz
  • For connecting to test points, SMA, MMCX, U.FL and square pins  are included
  • An optional handheld browser makes quick measurements up to 1 GHz

The trends toward more data, faster signals and increased power efficiency are here to stay. Tektronix low-noise oscilloscopes combined with the lowest additive noise provided by these new power rail probes represent the measurement solution you need to ensure clean, noise-free voltage sources in your designs.

Available for order with shipments expected to begin in late March 2019, the 1 GHz TPR1000 and 4 GHz TPR4000 single-ended power rail probes with the TPR4KIT accessory kit are priced at $4,000 and $6,000 respectively.
