Analog Bandwidth 0 - 1MHz
Maximum Sample Rate 1Msps 12Bits
Sample Memory Depth 4096
Point Horizontal Sensitivity 1uS/Div~10S/Div (1-2-5 Step)
Horizontal Position Adjustable with Indicator Vertical Sensitivity 10mV/Div~10V/Div (with ×1 Probe) 0.5V/Div~100V/Div (with ×10 Probe)
Vertical Position Adjustable with Indicator
