Acquisition Modes

Random Interleaved Sampling (RIS): 200 GS/s for repetitive signals (SDA
18000/13000/11000/9000: RIS mode is available in 6 GHz mode only)
Single-Shot: For transient and repetitive signals: 20 ps/div to 1000 s/div; (SDA
18000/13000/11000/9000 in 6 GHz mode only): 20 ps/div to 1 µs/div
Sequence: 2 to 40,000 segments (number of segments depends upon memory options)
Intersegment Time: 6 µs (typical)

Acquisition Processing

Averaging: Summed averaging to 1 million sweeps; Continuous averaging to 1 million
sweeps
Enhanced Resolution (ERES): From 8.5 to 11 bits vertical resolution
Envelope (Extrema): Envelope, floor, roof for up to 1 million sweeps

Triggering System

Modes: Normal, Auto, Single, and Stop
Sources: Any input channel, External, EXT X10, EXT/10, or line; slope and level unique to
each source (except line trigger; disabled channels cannot be used as a trigger source in
SDA 18000, SDA13000, SDA 11000, or SDA 9000 when operating in 18 GHz, 13 GHz, 11
GHz, or 9 GHz modes.)
Coupling Modes: DC
Pre-trigger delay: 0 to 100% of memory size (adjustable in 1% increments)
Post-trigger delay: smaller of 0 to 10,000 divisions or 86400 seconds
Hold-off by time or events: Up to 20 s or from 1 to 99,999,999 events
Internal trigger range: ±4.1 div from center
Max. trigger frequency: Up to 5 GHz with Edge Trigger; 750 MHz with SMART Trigger
