Handheld 10MHz 50MSa/s Oscilloscope Scopemeter & True RMS Multimeter 2in1 USB
Features:
• Combination of a 4000 count auto-range True RMS DMM
and
a handheld Digital Storage Oscilloscope at the size and the
cost of a multimeter
• DMM functions include True RMS AC/DC voltage and current,
resistance,
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
