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.
Trigger Operating Modes - Peak-Peak AUTO (also for TV LINE), NORM, TV FIELD, SGL, SWP.
Deflection Factors - Same as vertical system.
Bandwidth - X-Axis: 2.5 MHz in nonstore mode, up to 100 MHz in store mode. Y-Axis: same as vertical system.
