Returning the probe for servicing
If your probe requires servicing, you must return the probe to Tektronix. If the original packaging is un fit for use or not
available, use the following packaging guidelines:
Preparation for shipment
1. Use a corrugated cardboard shipping
carton having inside dimensions at
least one inch greater than the probe
dimensions. The box should have a
carton test strength of at least 200
pounds.
Read this Instruction Manual.
2. Put the probe into an antistatic bag or
wrap it to protect it from dampness.
3. Place the probe into the box and stabilize
it with light packing material.
4. Seal the carton with shipping tape.
5. Refer to Contacting Tektronix at the
beginning of this manual for the shipping
address.

Whyuseapower-railprobe?
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 do not 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, e tc.) on DC rails that could affect data signals, clocks, etc.
The TPR1000 and TPR4000 provide a best-in-class 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.
Theory of operation
The block diagram shows the major circuit blocks or modules in the TPR1000 and TPR4000 probes.
Preface
Figure i: TPR1000 and TPR4000 clock diagram
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. The LF amplifier can be disconnected when DC offset is not needed by setting the
coupling mode to DC reject in the instrument vertical menu. The bypass capacitor acts as a low impedance path for high
frequency components while blocking low frequency components. Because the TPR1000 and TPR4000 are designed for
measuring the low source impedances of power distribution planes it is not recommended to measure devices with source
impedances >1 Ω as it may cause distortion of the waveform.

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 μVp-p and 1 Vp-p at up to 4 GHz. Key features include:

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

Connecting to the host instrument
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 host
instrument reads information from the
probe and identifies the device.
NOTE. Allow the probe to warm up for at
least 20 minutes to achieve guaranteed
specifications.
2. Attach one of the following probe cables
to the SMA connector on the probe body.
Limit SMA nut torque to 8 in-lbs for either
attachment or removal:
