Connecting Tips to Circuit
To measure the AC fluctuation of a DC rail, you may make
any of the following connections to the circuit.
Direct MCX Connection
1. Solder the MCX PCB mount to the board.
• Solder the center pin to the signal.
• Solder one or more of the four posts to ground.
CAUTION: Avoid excessive lateral or vertical force
on the mount once it has been installed.
2. Mate the MCX extension cable to the mount by
pressing the plug into the PCB receptacle.
For full instructions, see TE Connectivity, P/N 1061015-1.
Direct U.FL Connection
1. Solder the U.FL PCB mount to the board (maximum
temperature 350 C for five minutes).
°
2. Mate the U.FL coaxial cable to the PCB receptacle by
aligning the connectors and pressing the cable plug
into the receptacle. A click confirms proper mating.
CAUTION: Do not apply a load in excess of 2 N
parallel to or 4 N perpendicular to the mating axis.
Do not forcefully twist or deform the wires.
For full instructions, see Hirose, P/N U.FL-R-SMT-1. Also
see Lighthorse, P/N CB1.32D-IPX-MXMGT-4In-X1.
The Teledyne LeCroy RP2060 and RP4060 Power Rail Probes
meet the specific requirements of those who need to acquire
a low-voltage DC signal for testing digital power management
components (e.g., PMICs, VMRs, POL switching regulators).
The rail probes will acquire a low-impedance, low-voltage DC
bus signal without loading the device under test (DUT). They
provide high sensitivity (gain) with low noise and high offset―
allowing a DC bus signal to be displayed in the vertical center
of the oscilloscope.

Solder-in Connection
1. Solder the exposed ~3 mm inner conductor of the SI-lead
to the DC rail.
2. Solder the exposed ~0.5 mm outer conductor to ground
with as short of a lead as possible.
Outer conductor
soldered to ground
NOTE: SI-leads can be re-soldered multiple times.
See the User Manual for instructions.
Browser Connection
CAUTION: Maximum Safe Input Voltage for hand-held
use is 60 Vdc (referenced to ground) per
IEC/EN 61010-031:2015. Bandwidth is limited to
500 MHz when using the browser tip.
1. Remove the MCX extension cable from the rail probe.
2. Attach the browser cable to the SMA connector on the
probe housing.
3. Place the browser tip on the test point, keeping the body
as perpendicular to the circuit as posible to minimize
parasitic capacitance.
4. Place the adjacent ground tip on a nearby ground. The
hinged ground can be gently pulled away from or toward
the browser tip to fit it to the ground point.
See the User Manual for instructions on using the browser tip
as a transmission line probe.

Probe Assembly and Connection
1. Attach the SMA-to-MCX extension cable to the SMA
connector on the bottom of the probe housing.
2. Press the probe housing onto the oscilloscope ProBus
connector. A click confirms it is seated properly.
3. Attach the desired tip (if any) to the extension cable.
4. Allow the probe to warm up for at least 20 minutes
after being connected to the oscilloscope before
making measurements.
Operating from the Oscilloscope
When the probe is attached to the oscilloscope's input
connector, the instrument will recognize the probe and:
• Set the input termination (coupling) to DC50Ω
• Set the probe attenuation to 1.2x
Attenuation and Coupling cannot be changed.
The probe's attributes are shown on the RPxx60 Probe
dialog, which appears when a probe is detected.
Inner conductor
soldered to DC rail
Vertical Scale (V/div)
The oscilloscope automatically factors in the nominal 1.2x
attenuation and adjusts the Vertical Scale (gain) to reflect
the attenuation value. No further adjustment is needed.
Offset
Probe offset is controlled using the front panel Vertical
OFFSET knob. The amount of offset applied is displayed
on the input channel descriptor box.
NOTE: On Teledyne LeCroy oscilloscopes, the input offset
displayed is the amount of offset required to zero the
applied voltage (e.g., a -1 V offset is required to vertically
center a 1 V DC rail on the grid).
Bandwidth
Bandwidth is limited to the lower of the probe or tip
rating. Use the Bandwidth control on the Cn dialog to limit
bandwidth to less than the rating of probe or tip.
Auto Zero
After 20 minutes of warm-up, or when the probe is
exposed to a large shift in ambient temperature, some DC
offset drift may occur. Open the RPxx60 dialog and touch
Auto Zero to remove any DC offset drift.
