Preface
Key features
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
μ
Vp-p and 1 Vp-p at up to 4 GHz. Key features include:
Oscilloscope compatibility

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 speci
fi
ed accuracy of the probe is maintained.

DPO70000 oscilloscopes require the optional TCA-VPI50 adapter.

The comp box and oscilloscope temperature range is limited to the oscilloscope operating conditions. Please refer to the oscilloscope speci
