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.

Probe offset
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. Using the offset to cancel DC signal components enables optimal probe performance.
(See Figure 2 on page 6.)
NOTE. See your oscilloscope manual for specific instructions on using the offset control.
To set the probe offset, follow these steps:
1. Set the probe offset equal to the expected nominal DC value of the source you are connecting to.
2. Set the vertical scale to 500 mV/div.
3. Connect the probe to the circuit.
4. Change the volts/div setting to the desired range, adjusting the offset as needed to keep the signal in the center of
the screen.
The probe has a ±60 V offset range. The linear operating r ange is ±1 V. (See Figure 2 on page 6.) When you adjust the
probe offset with no signal applied to the probe input, the output range is ±1 V, (the linear operating range of the probe),
not the ±60 V offset range of the probe. However, when you apply up to ±60 V to the probe input, the probe offset control
canzerothisoffset.
Basic operation
NOTE. If the signal on the screen displays an offset that is either 1 Volt higher or lower than expected, check to make sure
the DUT is connected and operating. This is a result of the input to the LF amplifier being clamped at one extreme of
the dynamic range when no input is present.
Connect MMCX accessories
Gently insert the MMCX end of the cable into one of the following accessories: micro-coax tip, solder flex tip, u.fl adapter or
MMCX to square pin Y-lead adapter, until you feel the connector engage. To remove an accessory, gently pull from the
MMCX connection point, being careful to only grip the knurled metal area of the connector.

MMCX-to-square-pin adapter. To install the solder pins, use the supplied soldering-aide tool as described below
NOTE. The solder pins are extremely small and can be challenging to handle. It is recommended to use tweezers and
a magnifying tool when installing pins on a circuit board.
1. Carefully insert the solder pins into the soldering aide tool as shown below.
2. Use the soldering aide tool to hold the solder pins in place while soldering the pins to the circuit board.
3. If necessary, apply a small amount of adhesive to further strengthen the connection to the circuit board. However, keep
the height of the adhesive to a minimum to provide good electrical contact for the adapter.

Probing principles
Follow these helpful hints to make probing easier and noise free.
Ground lead length
When you are probing a circuit, you should
always use as short a ground lead as
possible between the probe head and circuit
ground. (See the illustration for the effects of
lead length on waveform distortion.)
The series inductance added by the probe
tip and ground lead can result in a resonant
circuit; this circuit may cause parasitic ringing
within the bandwidth of your oscilloscope.

Ground lead in
When you touch your probe tip to a circuit element, you are introducing a new resistance, capacitance, and inductance
into the circuit.
You can determine if ground lead effects may
be a problem in your application if you know
the self-inductance (L) and capacitance (C)
of your probe and ground lead. Calculate the
approximate resonant frequency (f
this parasitic circuit will resonate with the
following formula:
The equation shows that reducing the ground
lead inductance will raise the resonant
frequency. If your measurements are
affected by ringing, your goal is to lower
the inductance of your ground path until the
resulting resonant frequency is well above
the frequency of your measurements.
The low-inductance ground contacts
described in Accessories can help you
reduce the effects of ground lead inductance
on your measurements.

2. The graph below show the plotted example values.
Figure 8: Example plot of measured values
The gain slope can either be obtained by using a spreadsheet to calculate the linear regression of the points, or graphically
by hand. To obtain the gain slope graphically, carefully plot each measurement point on a rectangular coordinate system,
the X axis is the DC source voltage and the Y axis is the measured DC output value. Using a straight edge, draw a line
through the points, minimizing the error between the line and each point. The gain slope is taken by the slope of the
drawn line (rise in Y divided by run in X), and the zero point error taken at the point at which the line crosses the Y axis.
The DC output value can be predicted by the following equation:
