The RIGOL PVP2150, PVP3150 and PVP2350 are high-impedance passive oscilloscope probes designed for general electronics measurement, circuit debugging, laboratory testing, maintenance and education. Each model provides switchable 1X and 10X attenuation, allowing users to choose between direct signal observation and reduced circuit loading with a wider measurement range.
Switchable 1X and 10X Attenuation
The integrated attenuation switch makes each probe suitable for a wide variety of measurement tasks. The 1X setting is useful for observing lower-amplitude signals without attenuation, while the 10X setting provides higher bandwidth, increased input resistance and lower input capacitance for improved high-frequency measurements.
-
1X mode: 1MΩ input resistance and 50pF input capacitance
-
10X mode: 10MΩ input resistance and 10pF input capacitance
-
Compensation range: 10pF to 25pF
-
Connector: Standard BNC oscilloscope connection
Bandwidth Options up to 350MHz
The series covers general-purpose and higher-speed signal measurements. The PVP2150 and PVP3150 provide up to 150MHz bandwidth in 10X mode, while the PVP2350 extends the available bandwidth to 350MHz for faster digital edges, clock signals, switching waveforms and other higher-frequency applications.
High-Impedance Signal Measurement
In 10X mode, the probes provide 10MΩ input resistance with approximately 10pF input capacitance. This reduces loading on the circuit under test and helps preserve waveform characteristics when measuring sensitive or higher-frequency nodes.
Frequency Compensation Adjustment
An integrated compensation adjustment allows the probe to be matched to the oscilloscope input capacitance. Proper compensation helps maintain accurate square-wave response and minimizes waveform overshoot, rounding and distortion. The probe should be compensated after connecting it to an oscilloscope and before critical measurements are performed.
CAT II Measurement Rating
All three models support a maximum rated input of 150VRMS CAT II in 1X mode and 300VRMS CAT II in 10X mode. The applicable voltage limit decreases as signal frequency increases, so measurements must follow the voltage-derating information and safety instructions in the probe user guide.
Model Differences & Selection
-
PVP3150: Provides 20MHz bandwidth in 1X mode and 150MHz bandwidth in 10X mode. Select it for general-purpose measurements where 10X operation is normally used and extended 1X bandwidth is not required.
-
PVP2150: Provides 35MHz bandwidth in 1X mode and 150MHz bandwidth in 10X mode. Choose it instead of the PVP3150 when you need the same 150MHz 10X performance together with higher bandwidth in 1X mode.
-
PVP2350: Provides 35MHz bandwidth in 1X mode and 350MHz bandwidth in 10X mode. Select it for higher-bandwidth oscilloscopes, faster rise-time measurements, clock signals, pulse analysis and high-speed digital troubleshooting.
The measurement system bandwidth is limited by the lower bandwidth of the probe and oscilloscope. The PVP2350 therefore provides its greatest benefit when paired with an oscilloscope and signal path capable of supporting its 350MHz bandwidth.
