Trigger system

Trigger modes Auto, Normal, and Single

Trigger coupling DC, HF reject (attenuates >85 kHz), LF reject (attenuates <65 kHz), noise reject (reduces sensitivity)

Trigger holdoff range 20 ns to 8 s

Trigger sensitivity, typical

Trigger source Sensitivity

Internal DC coupled 0.4 div from DC to 50 MHz

0.6 div > 50 MHz to 100 MHz

0.8 div > 100 MHz to 200 MHz

External (aux input) 200 mV from DC to 100 MHz, 1X attenuation

Trigger level ranges

Any input channel ±4.92 divisions from center of screen

Aux Input (external trigger) ±6.25 V, 1X attenuation

±12.5 V, 10X attenuation

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.

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

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, NAND) 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.

C (optional) Trigger on Start, Repeated Start, Stop, Missing ACK, Address (7 or 10 bit), Data, or Address and Data on I

C buses up to 3.4 Mb/

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.

Parallel (available on MSO

models only)

Trigger on a parallel bus data value.
