PINTECH RT250M is a cost-effective dual-range passive oscilloscope probe with DC~250MHz bandwidth, supporting quick 1X/10X attenuation switching via body toggle switch, compliant with CAT II 600V safety voltage standard. It is compatible with all analog and digital oscilloscopes from 100MHz to 250MHz. Adopting precision voltage divider low-noise structure and built-in adjustable compensation capacitor, it matches oscilloscopes with input capacitance 10~35pF to eliminate waveform ringing and overshoot distortion. Passive design requires no external power supply with universal BNC connector, equipped with full insulated test accessories and excellent cost performance. Widely used for medium & low frequency waveform measurement of switching power supplies, home appliance control boards, low-voltage inverter circuits, automotive low-voltage ECUs, teaching labs and production line inspection.
