Page 11: Preface
Access this document and other related information from the tek.com. 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 μV...
Page 12: Operating Information
The block diagram shows the major circuit blocks or modules in the TPR1000 and TPR4000 probes. The TPR1000 and TPR4000 function by extending the oscilloscopes offset capability while maintaining a low noise signal path into the instrument. The linear dynamic range can be moved around the offset voltage operating window using the DC offset control into the LF amplifier.
Page 13: Connecting To The Instrument
Operating information Connecting to the instrument The following steps describe the process for connecting the TPR1000 and TPR4000 probes. Procedure 1. Slide the probe body into the FlexChannel or VPI receptacle. The probe clicks into place when fully engaged. When the probe is connected, the instrument reads information from the probe and identifies the device.

2 mV/division. For all other vertical scale settings, the specified accuracy of the probe is maintained. To take accurate measurements when using a TPR1000 or TPR4000 probe with the oscilloscope models below, it is recommended to use vertical scale settings greater than 2 mV/division.
Page 18: Probe Offset
Operating information Figure 1: Dynamic and offset limitations Probe offset Use the following instructions for setting the probe offset. Before you begin See your oscilloscope user manual for specific instructions on using the offset control. About this task The probe offset is adjustable for operation within the linear range of the probe, and to increase the sensitivity of the probe at higher DC measurement voltages.

4. Place a marker on the S21 trace at the start frequency (300 kHz). 5. Place a marker on the S21 trace at the probe bandwidth (1 GHz for TPR1000 or 4 GHz for TPR4000). 6. Verify that the amplitude is greater than -3.97 dB (subtracting the 0.97 dB of probe attenuation range from the 3.97 dB target value yields the 3 dB limit).
