Acquisition mode
5 GSa/s half channel interleaved, 2.5 GSa/s all channel
4 Mpts half channel interleaved, 2 Mpts all channel
Default mode
Normal
Peak detect Capture glitches as narrow as 250 ps at all-time base settings
Averaging
High
resolution
Segmented
Selectable from 2, 4, 8, 16, 64, ... to 65,536
Real-time boxcar averaging reduces random noise and effectively increases vertical resolution to
12 bits of resolution when ≥ 10 μs/div at 5 GSa/s or ≥ 20 μs/div at 2.5 GSa/s
Segmented memory optimizes available memory for data streams that have long dead times
between activity. Maximum segments = 1000. Re-arm time = 1 μs (minimum time between trigger
events)

Trigger sources
Trigger modes
Analog channel (1-2), external, WaveGen (1 or mod) (FM/FSK)
Normal (triggered): Requires trigger event for scope to trigger
Auto: Triggers automatically in absence of trigger event
Single: Triggers only once on a trigger event, press [Single] again for scope to find another trigger
event, or press [Run] to trigger continuously in either Auto or Normal mode
Force: Trigger immediately and display acquisition
Trigger coupling
DC: DC coupled trigger
AC: AC coupled trigger, cutoff frequency: < 10 Hz (internal); < 50 Hz (external)
HF reject: High-frequency reject, cutoff frequency ~ 50 kHz
LF reject: Low-frequency reject, cutoff frequency ~ 50 kHz
Noise reject: Selectable OFF or ON, decreases sensitivity 2x
40 ns to 10.00 s
