The RIGOL RP3500A is a fixed 10:1 passive oscilloscope probe with DC–500MHz bandwidth for measuring high-speed signals in electronic circuits. Its 10MΩ input resistance reduces loading on the device under test, making it suitable for laboratory development, PCB debugging, signal-integrity investigation and general waveform analysis.
A 6pF–24pF compensation range allows the probe response to be adjusted to the oscilloscope input. The 140cm cable provides practical reach across laboratory benches and larger test assemblies.
Key Features
-
DC–500MHz bandwidth: Supports waveform observation in digital, communication and high-speed electronic circuits.
-
Fixed 10:1 attenuation: Extends the practical measurement range while reducing the electrical load applied to the circuit.
-
10MΩ input resistance: Minimizes current drawn from the test point for more representative waveform measurements.
-
13pF input capacitance: Provides a defined capacitive load for evaluating probe suitability in high-frequency applications.
-
6pF–24pF compensation range: Enables low-frequency compensation across a broad range of compatible oscilloscope inputs.
-
CAT II 300VAC rating: Supports measurements within the specified IEC Measurement Category II limits.
-
140cm cable: Offers convenient access to test points across development benches and equipment assemblies.
-
Grounding accessories: Ground spring and alligator ground connection support both short-ground high-frequency measurements and general circuit testing.
Low-Frequency Compensation
The RP3500A includes a low-frequency compensation adjustment for matching the probe response to the oscilloscope input. Correct compensation preserves square-wave shape and improves amplitude and timing accuracy across the measurement bandwidth.
Compensation is performed by connecting the probe to the oscilloscope calibration output and adjusting the compensation point until the displayed square wave has a flat top without excessive rounding or overshoot.
Typical Applications
- High-speed digital circuit debugging
- PCB signal and clock-line measurement
- Embedded-system development
- Power-supply control signal analysis

Compatibility and Selection
The RP3500A is designed for high-impedance oscilloscope inputs with a compensation range between 6pF and 24pF. Its standard probe connection and fixed 10:1 attenuation make it suitable for supported RIGOL oscilloscopes, including the MSO/DS7000, DS6000, MSO8000A and MHO/DHO5000 families.
This model is the appropriate choice when 500MHz probe bandwidth and low circuit loading are required. Applications requiring switchable 1:1 attenuation, differential measurement, current measurement or electrical isolation require a different probe type.
Why Choose the RIGOL RP3500A?
The RP3500A combines 500MHz bandwidth, 10MΩ input resistance and adjustable compensation in a lightweight passive probe. It provides a direct measurement solution for engineers and technicians who need to capture high-speed single-ended signals without the power requirements or additional controls of an active probe.
