Digital Storage System
Sample Rate - 20 MS/s max; 10 MS/s dual channel. Effective sample rates up to 2 GS/s in repetitive storage mode (2 ms/div and faster).
Resolution - Vertical - 8 bits (25 levels per division), 10 bits with average mode. Horizontal - 10 bits (100 points per division). 9 bits per channel in dual channel mode.
Record Length - 4K (2K per channel in dual channel)
Pre/Post Trigger - 1/8, 1/2. or 7/8 trigger position selectable.
Acquisition Modes - Peak Detect (100 ns glitch capture at all available sweep speeds); Accumulated Peak Detect; Average; Sample.
Save Reference Memory - One 4K acquisition.
Vertical System (2 Channels)
Bandwidth (3 dB) and Rise Time - 100 MHz and 3.5 ns (80 MHz and 4.4 ns at 2mV/div).
Deflection Factor - 2 mV/div to 5 V/div.
Vertical Operating Modes - CH1, CH2, CH2 INVERT, ADD, ALT, CHOP (500 kHz), and XY.
