The Kit includes (2) 60MHz probes and heavy duty carrying case. (PS4424 4-ch scope pictured). Do you need to make measurements from small signals to large voltages? The PicoScope 4000 Series oscilloscopes can be set to measure input ranges from ±50 mV to ±100 V full-scale to allow measurements from small sensor output signals as well as higher voltages from motor drives and power supply circuits. The high-resolution 2-channel PicoScope 4224 is a PC-based oscilloscope that suits a wide range of general, scientific and field-service applications. With 12-bit resolution that is adjustable up to 16 bits in enhanced resolution mode, as well as 1% accuracy, these high quality scopes also make an excellent measurement choice for noise, vibration and mechanical analysis.
