capacitance, frequency, duty cycle, dBm, diode and continuity tests
• Full auto set up for volt/div and time/div of DSO
• DSO Trigger mode: Auto/normal/single
• DSO Auto measure: Vpp, Vavg, Vrms, dBm
• DSO Cursor readout: dV, dt, 1/dt (frequency)
• Screen hold function
• Save and recall up to 100 waveform and data
• High contrast FSTN LCD with white LED backlight
