Trigger system

Trigger modes

Auto, Normal, and Single

Trigger coupling

DC, AC, HF reject (attenuates >50 kHz), LF reject (attenuates <50 kHz), noise reject (reduces sensitivity)

Trigger holdoff range

20 ns to 8 s

Trigger sensitivity, typical

Edge type, DC coupled

Trigger Source

Sensitivity

Any input channel

0.50 div from DC to 50 MHz, increasing to 1 div at oscilloscope

bandwidth

Aux input (external trigger)

200 mV from DC to 50 MHz, increasing to 500 mV at 250 MHz

Line

Fixed

Trigger level ranges

Any input channel

±8 divisions from center of screen, ±8 divisions from 0 V when vertical LF reject trigger coupling is selected

Aux Input (external trigger)

±8 V

Line

The line trigger level is fixed at about 50% of the line voltage.

Trigger types

Edge

Positive or negative slope on any channel or front-panel auxiliary input. Coupling includes DC, AC, HF reject, LF reject, and noise

reject.

Sequence (B-trigger)

Trigger Delay by Time: 8 ns to 8 s. Or Trigger Delay by Events: 1 to 9,999,999 events.

Pulse Width

Trigger on width of positive or negative pulses that are >, <, =, ≠, or inside/outside a specified period of time.

Timeout

Trigger on an event which remains high, low, or either, for a specified time period (4 ns to 8 s).

Runt

Trigger on a pulse that crosses one threshold but fails to cross a second threshold before crossing the first again.

Logic

Trigger when any logical pattern of channels goes false or stays true for specified period of time. Any input can be used as a clock

to look for the pattern on a clock edge. Pattern (AND, OR, NAND, NOR) specified for all input channels defined as High, Low, or

Don’t Care.

Setup and Hold

Trigger on violations of both setup time and hold time between clock and data present on any of the analog and digital input

channels.

Rise/Fall Time

Trigger on pulse edge rates that are faster or slower than specified. Slope may be positive, negative, or either.

Video

Trigger on all lines, odd, even, or all fields on NTSC, PAL, and SECAM video signals.

Extended Video (optional)

Trigger on 480p/60, 576p/50, 720p/30, 720p/50, 720p/60, 875i/60, 1080i/50, 1080i/60, 1080p/24, 1080p/24sF, 1080p/25, 1080p/

30, 1080p/50, 1080p/60, and custom bi-level and tri-level sync video standards.

SPI (optional)

Trigger on SS, MOSI, MISO, or MOSI and MISO on SPI buses up to 10.0 Mb/s.

RS-232/422/485/UART

(optional)

Trigger on Tx Start Bit, Rx Start Bit, Tx End of Packet, Rx End of Packet, Tx Data, Rx Data, Tx Parity Error, and Rx Parity Error up

to 10 Mb/s.

CAN (optional)

Trigger on Start of Frame, Frame Type (data, remote, error, overload), Identifier (standard or extended), Data, Identifier and Data,

End of Frame, Missing ACK, or Bit Stuffing Error on CAN signals up to 1 Mb/s. Data can be further specified to trigger on ≤, <, =,

>, ≥, or ≠ a specific data value. User-adjustable sample point is set to 50% by default.

LIN (optional)

Trigger on Sync, Identifier, Data, Identifier and Data, Wakeup Frame, Sleep Frame, Errors such as Sync, Parity, or Checksum

Errors up to 100 kb/s (by LIN definition, 20 kb/s).

FlexRay (optional)

Trigger on Start of Frame, Type of Frame (Normal, Payload, Null, Sync, Startup), Identifier, Cycle Count, Complete Header Field,

Data, Identifier and Data, End of Frame or Errors such as Header CRC, Trailer CRC, Null Frame, Sync Frame, or Startup Frame

Errors up to 100 Mb/s.
