Tektronix TPR1000 and TPR4000 Active Power Rail Probes

The TPR1000 and TPR4000 probes provide a low noise, large offset range solution for measurement of ripple on DC power rails ranging from –60 to +60 VDC. Tektronix’s power rail probes offer industry leading low noise and high offset range required to measure AC ripple between 200 μVp-p and 800 mVp-p at up to 4 GHz.

Key performance specifications
  • Compatible with the 6 series MSO, 5 series MSO, 4 Series MSO, 3 Series MDO, MDO3000, MDO4000C, MSO/DPO5000B, DPO7000C, and DPO70000C/DX/SX oscilloscopes. Due to software incompatibilities between the TPR1000 and TPR4000 probes and the MDO3000 and MDO4000C oscilloscopes, the accuracy of probe measurements is reduced when these oscilloscopes are used in vertical scale settings less than 2 mV/division. For all other vertical scale settings, the specified accuracy of the probe is maintained. DPO70000 oscilloscopes require the optional TCA-VPI50 adapter.
