TESTEC示波器探头SI-90002
型号: PXF2313
Differential probes SI-9001, SI-9002
When you use the oscilloscope in its usual context to show and measure circuit shaft formations, you are working in the most common mode for voltage measurements. The differential probe enhances the oscilloscope probe's measuring capabilities with performance conversion, inverters, motor speed indicators, switch mode power supplies and many 其他 applications.
