Sweep Modes

Auto, triggered, single

Trigger Coupling

DC, AC, low frequency reject (50 kHz high pass filter), high frequency reject

(50 kHz low pass filter)

Trigger Conditioning

Noise reject adds hysteresis to trigger circuitry decreasing sensitivity to noise

Trigger Holdoff Range

80 ns to 320 ms (54830A/B Series)

50 ns to 10 s (54830D Series)

Trigger Jitter

8 ps ± 0.05 ppm x |delay setting| rms

Trigger Actions

Specify an action to occur, and the frequency of the action, when a trigger condition

occurs. Actions include: e-mail on trigger and QuickMeas+

Trigger Modes

Edge

Triggers on a specified slope and voltage level on any channel, auxiliary trigger (4 channel models),

external trigger (2 channel models) or line input.

Glitch

Triggers on glitches narrower than the other pulses in your waveform by specifying a width less

than your narrowest pulse and a polarity. Minimum glitch width is 500 ps (analog channels) or

2.5 ns (digital channels on 54830D/31D/32D/33D). Glitch range settings: <1.5 ns to <160 ms

(54830A/B Series), <1.5 ns to <10 s (analog channels on 54830D/31D/32D/33D),

<5 ns to <10 s (digital channels on 54830D/31D/32D/33D)

Line

Triggers on the line voltage powering the oscilloscope.

Pattern

Triggers when a specified logical combination of the channels is entered, exited, is present or

absent for a specified period of time or is within a specified time range. Each channel can have a

value of High (H), Low (L) or Don’t care (X).

State

Pattern trigger clocked by the rising or falling edge of one channel. Logic type: AND or NAND.

Delay by Time

The trigger is qualified by an edge. After a specified time delay between 30 ns to 160 ms (5 ns to

10 s for 54830D/31D/32D/33D) a rising or falling edge on any one selected input will generate

the trigger.

Delay by Events

The trigger is qualified by an edge. After a specified delay between 1 to 16,000,000 rising or falling

edges on any one selected input will generate the trigger.

TV

Trigger on one of the three standard television waveforms: 525 lines/60 Hz (NTSC)

625 lines/50 Hz (PAL), or define a custom waveform

Violation Triggers

Pulse Width

See Trigger Mode Glitch for performance characteristics.

Setup/Hold

Triggers on setup, hold or setup and hold violations in your circuit. Requires a clock and data signal

on any two input channels as trigger sources. High and low thresholds and setup and/or hold

time must then be specified.

Transition

Trigger on pulse rising or falling edges that do not cross two voltage levels in > or < the amount of

time specified.
