Your oscilloscope is the newest version of a series that set the standard for monochrome DSO's (Digital Storage Oscilloscopes). Each of the scope’s channels has an 8-bit ADC (Analog–to–Digital Converter). On the higher-range models, combining two channels doubles the scope’s sampling rate. While on high-range, four-channel models, combining all channels increases the original rate by four times. LEADING SPECIFICATIONS • 500 MHz and 1 GHz Bandwidth • 2 GS/s and 4 GS/s Max.
