Trigger system

P9241A P9242A P9243A

Trigger sources Analog channel (1-2), external, WaveGen (1 or mod) (FM/FSK)

Trigger modes 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

Trigger holdoff range 40 ns to 10.00 s

Trigger sensitivity

Internal

< 10 mV/div: Greater of 1 div or 5 mV; ≥ 10 mV/div: 0.6 div

External

200 mVpp from DC to 100 MHz

350 mVpp 100 to 200 MHz

Trigger level range

Any channel ± 6 div from center screen

External ± 8 V

Acquisition system

P9241A P9242A P9243A

Maximum analog channels sample

rate

5 GSa/s half channel interleaved, 2.5 GSa/s all channel

Maximum analog channels record

length

4 Mpts half channel interleaved, 2 Mpts all channel

Acquisition mode Normal Default mode

Peak detect Capture glitches as narrow as 250 ps at all-time base settings

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 to

12 bits of resolution when ≥ 10 μs/div at 5 GSa/s or ≥ 20 μs/div at 2.5 GSa/s

Segmented 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)

Time mode Normal Default mode
