Acquisition system
1 GHz 2.5 GHz 4 GHz 6 GHz
Maximum analog channels sample rate 20 GSa/s half channel interleaved, 10 GSa/s all channel
Analog channels equivalent sample rate Not available 400 GSa/s
Maximum analog
channels record length
≤ 2 GSa/s 4 Mpts half channel interleaved, 2 Mpts all channel
> 2 GSa/s 1 Mpts half channel interleaved, 500 kpts all channel
Maximum digital channels sample rate 2 GSa/s half pods interleaved, 1 GSa/s all pods
Maximum digital channels record length 4 Mpts half pods interleaved, 2 Mpts all pods
Acquisition mode Normal Default mode
Peak detect Analog channels: Capture glitches as narrow as 500 ps (half channel), 1 ns (all channel)
Digital channels: Capture glitches as narrow as 500 ps (half pods), 1 ns (all pods)
Averaging Selectable from 2, 4, 8, 16, 64, ... to 65,536
High resolution Real-time boxcar averaging reduces random noise and effectively increases vertical resolution
12 bits: ≥ 20 μs/div at 2 GSa/s or ≥ 50 μs/div at 1 GSa/s
Segmented Segmented memory optimizes available memory for data streams that have long dead times
between activity. Maximum segments = 1000. Re-arm time = As fast as 1 μs (minimum time
between trigger events)
Data acquisition mode Real time Default mode (> 135,000 waveforms/sec)
Max update rate Enhanced real-time mode for the fastest waveform update rate of > 450,000 waveforms/sec. Up to
2 GSa/s. Returns to a normal real-time mode at > 2 GSa/s
Equivalent Available with 6-GHz bandwidth license. The time base must be at 20 ns/div or faster. 2.5-ps fine
interpolator resolution yields a maximum effective sample rate of 400 GSa/s
Time mode Normal Default mode
Roll Displays the waveform moving across the screen from right to left. Available at time bases 50 ms/div
or slower
XY Shows the volts-versus-volts display. Time base can be set from 200 ns/div to 50 ms/div
Trigger system
Trigger sources Analog channel (1~4), digital channel (D0~D15), line, external, WaveGen (1, 2, or Mod (FM/FSK))
Trigger modes Normal Requires trigger event for oscilloscope to trigger
Auto Triggers automatically but not synchronized to the input in absence of trigger event
Single Front panel button that triggers only once on a trigger event. Press Single button again for
oscilloscope to find another trigger event, or press Run front panel button to trigger continuously in
either Auto or Normal mode
Force Front panel button forces a synchronous trigger
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 Adds hysteresis to the trigger circuitry; selectable OFF or ON, decreases sensitivity 2x
Trigger holdoff range 40 ns to 10.00 s
