The PINTEK DP-22Kpro is a high-voltage differential probe that lets an oscilloscope display the voltage difference between two circuit nodes. Request probe rental or measurement services for power-electronics development, troubleshooting, and maintenance in Monterrey, Mexico.
What a differential probe does
The probe attenuates the differential input voltage and supplies a lower-amplitude signal to the oscilloscope. It supports the evaluation of floating signals and nodes that cannot be connected directly to a conventional passive-probe reference. A compatible oscilloscope and measurement configuration are required.
Model characteristics
- Manufacturer-advertised bandwidth up to 120 MHz, depending on attenuation and operating conditions.
- Five selectable attenuation settings: ×30, ×100, ×300, ×1000, and ×3000.
- Power and over-range indicators.
- BNC output for connection to the measurement instrument.
- External power identified on the unit: 9 V DC.
The unit label lists maximum inputs of ±11 kV DC and 7.8 kV RMS AC at ×3000. These values do not replace the separate input-to-earth limits, measurement category, or operating conditions in the manual. Lower attenuation ranges have lower input limits.
Oscilloscope probe rental
Rent the probe for your bench or request a configuration with a compatible oscilloscope. The quotation identifies the probe, leads, tips, and power supply included. Output connection and required instrument input impedance are checked for the selected setup.
Power-electronics measurement services
- Differential-voltage waveform observation.
- Switch-mode supply, converter, and inverter troubleshooting within system limits.
- PWM, transient, and switching-behavior evaluation.
- Signal comparison before and after maintenance.
- Trace capture and a technical report with agreed test conditions and scope.
Power analysis also requires suitable current measurements and timing alignment. A voltage probe alone does not provide a complete power study.
Preparing the measurement
Provide the maximum differential voltage, each node voltage relative to earth, frequency range, and oscilloscope model. Selection covers the probe, leads, and accessories. Testing requires trained personnel following the manual and applicable work procedure, while preserving the oscilloscope protective-earth connection.
Request rental or services
Send the device under test, signals of interest, dates, and whether you need the probe alone or a measurement service with a report. Availability, accessories, and unit documentation are confirmed in the quotation.
