RP4030 Power Rail Probe Keep product surfaces clean and dry. Handle with care. Probe tips are sharp and may cause injury if not handled properly. Comply with the maximum input voltage vs. frequency derating when measuring voltage that includes a high frequency component.
Operator’s Manual Introduction The Teledyne LeCroy RP4030 Power Rail Probe meets the specific requirements of those who need to acquire a low-voltage DC signal as part of testing: Digital power management components such as power management IC (PMIC); • voltage regulator module (VMR); point-of-load (POL) switching regulator; or...

The RP4030 eliminates the above tradeoffs and permits more accurate and more convenient DC power/voltage rail probing at very high bandwidths. In the simplified circuit diagram below, the RP4030 portion is highlighted in gray. The input is through a high bandwidth SMA connector, terminated to ground with a 50 kΩ resistor in parallel with a 0.1 μF capacitor.
PCB. A separate browser tip accessory (the RP4000-BROWSER) is available at additional cost. If desired, the cable and lead connection components may be used separately from the RP4030 probe. This is useful for power sequencing tests where the dynamic range of the DC power/voltage rail exceeds the +/-800 mV rating of the probe.
RP4030 Power Rail Probe Probe Kit The following items are shipped with the RP4030 probe. Additional quantities of some parts may be purchased separately using the part number shown in the table. Item Description Part Number Extension Cable SMA to MCX extension cable, 0.9 meters...
SMA-to-SMA extension cable, while the other end of this cable terminates at the RP4030 probe, which then terminates at the oscilloscope with 50 Ω coupling with high input impedance. The spring-loaded, hinged ground pin contributes to contact stability while making it easier to reach into dense circuitry.
RP4030 Power Rail Probe Other RP4030 Accessories Additional quantities of the following accessories may be purchased with the RP4030 or separately. If ordered with the RP4030, they are shipped inside the RP4030 soft carrying case. Item Description Part Number Solder-in Leads...

Operator’s Manual Ultra-miniature U.FL Coaxial Cables Three are supplied with the RP4030, and more may be purchased as accessory or replacement items using part number RP4000-MCX-CABLE-UFL. U.FL is a Hirose Electric ultra-miniature connector that is ideal for use in very dense or compact circuits, and is functionally equivalent to IPX and UMCC connectors.
For the most current specifications, see the product datasheet at teledynelecroy.com. Specifications are subject to change without notice. NOTE: The components supplied as part of the RP4030 probe are tested as a system. The performance presented in this manual represents the probe when used with these components.

Coupling to DC50Ω. Bandwidth Limit The bandwidth of the RP4030 ranges up to 4 GHz (depending on the lead attachment). If it is desired to limit bandwidth to less than the rating, make a selection from the Cn dialog Bandwidth control.
DC offset drift. To invoke Auto Zero, open the Cn RP4030 dialog and touch Auto Zero. The probe contains an internal relay to disconnect the input from the probe amplifier while Auto Zero is performed, so the probe does not need to be disconnected from the DUT prior to invoking Auto Zero.

DC rail. Avoiding Parasitic Inductance All ground connections provided with the RP4030 are very short (browser) or coaxial in nature. This is to ensure any parasitic inductance added to the circuit when the probe connection is made remains low.

Operator’s Manual Connecting to High Impedance Sources The RP4030 is intended to probe low-impedance DC voltage and power rails. The probe’s input impedance is optimized to provide a flat frequency response from DC to rated bandwidth when the source impedance is very low. However, the probe input impedance declines from 50 kΩ...

RP4030 Power Rail Probe Using the Solder-in Lead The MCX cable to solder-in connection is a great solution for probing DC rails on a crowded board. The exposed ~3 mm inner conductor connected to the DC rail and the exposed ~0.5 mm outer conductor is connected to ground, ideally with as short a ground lead as possible.

Operator’s Manual Using the MCX PCB Mounts (Receptacles) The MCX PCB mount receptacle manufacturer is TE Connectivity and the part number is 1061015-1. This part is exceptionally durable and provides the highest bandwidth connection, but it has a larger footprint than other solutions. The center pin is soldered to the signal and one or more of the four posts are soldered to ground.

“pop” the plug out of the receptacle using lever action. Using the RP4000-BROWSER The browser is shipped with a pass-through 0 Ω resistor installed for use with the RP4030. To maintain the high performance capability of the probe in measurement applications, care must be exercised in connecting the probe to the test circuit.

5. Select the proper Attenuation on the input Channel (Cn) setup dialog. NOTE: The RP4030 will not work properly when a resistor other than 0 Ω is installed in the RP4000-BROWSER. If the resistor is changed and is not reverted to 0 Ω prior to using the browser with the RP4030, the voltages displayed on the oscilloscope will be incorrect.
RP4030 Power Rail Probe Performance Verification This procedure can be used to verify the warranted characteristics of an RP4030 probe. It tests: LF Attenuation Accuracy • Offset Accuracy • The recommended calibration interval for the RP4030 is one year. Perform the complete performance verification procedure as the first step of annual calibration.
2. Verify that the C1 RP4030 dialog tab appears behind the C1 setup dialog. This confirms the probe is sensed. 3. Open the C1 RP4030 dialog and touch Auto Zero then OK to Auto Zero the probe. 4. Confirm that the message "Performing Auto Zero on RP4030.." is displayed on the message bar and that no error messages appear.
