High-frequency test probe RP4060

interfaceelectriccoaxial

Product Overview
The RP4060 is a power/voltage rail probe designed for high-sensitivity oscilloscope measurements on power rails and low-amplitude dynamic signals superimposed on large DC offsets. It delivers 4 GHz bandwidth, 1.2× attenuation and a ±60 V offset range. The probe is supplied with solder-in leads and coaxial cables; browser tip sold separately.

Key Features

• 4 GHz bandwidth
• 110 ps rise time (10–90%)
• ±60 V offset range
• ±800 mV input dynamic range
• 1.2× nominal attenuation
• ±100 V non-destruct voltage
• 50 kΩ DC input resistance

Large Offset Range
The ±60 V offset range allows the DC component of the measurement to be positioned near the oscilloscope vertical center while using high-sensitivity gain settings, enabling clear observation of small dynamic signals riding on large DC voltages.

Low Attenuation and Noise
With a nominal 1.2× attenuation coupled to a 50 Ω oscilloscope input at DC, the probe minimizes additive noise and provides exceptionally low-noise performance at high sensitivity settings for improved measurement fidelity.

High DC Input Impedance
The 50 kΩ DC input impedance minimizes loading of power and voltage rails, preserving signal integrity and providing more accurate DC and low-frequency measurements on target circuits.

Wide Assortment of Tips and Leads
The RP2060/RP4060 ships with solder-in leads and coaxial cables with MCX and U.FL PCB receptacle mounts. Additional receptacles and leads are available as accessories and can be left connected in-circuit for quick switching between test points during validation and debugging.

Optional Browser Tip
A 500 MHz browser tip accessory is available. This transmission-line style tip provides a pass-through 0 Ω resistor to achieve 50 Ω tip impedance and 1× attenuation; it is also supplied with 450 Ω and 950 Ω resistors to configure the tip as conventional 10× or 20× transmission-line probes.
