Trigger System
Characteristic Description
Main 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
Characteristic Description
Internal DC Coupled 0.5 div from DC to 50 MHz, increasing to 1 div at
rated bandwidth
External
(Auxiliary Input)
200 mV from DC to 50 MHz increasing to 500 mV
at 250 MHz
Trigger Level Range
Characteristic Description
Any Channel ±8 divisions from center of screen
External
(Auxiliary Input)
±8 V
Trigger Modes
Mode Description
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 ≠ 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, OR, NAND, NOR) specified for all analog and digital 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 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.
I 2 C (optional) Trigger on Start, Repeated Start, Stop, Missing ACK, Address (7 or 10 bit), Data, or Address and Data on I 2 C buses up to 10 Mb/s.
SPI (optional) Trigger on SS, MOSI, MISO, or MOSI and MISO on SPI buses up to 10.0 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.
I 2 S/LJ/RJ/TDM
(optional)
Trigger on Word Select, Frame Sync, or Data. Data can be further specified to trigger on ≤, <, =, >, ≥, ≠ a specific data value, or inside
or outside of a range.
Maximum data rate for I2S/LJ/RJ is 12.5 Mb/s.
Maximum data rate for TDM is 25 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.
LIN (optional) Trigger on Sync, Identifier, Data, Identifier and Data, Wakeup Frame, Sleep Frame, Errors such as Sync, Parity, or Checksum Errors up to
1 Mb/s (by LIN definition, 20 kb/s).
Parallel (available
on MSO models
only)
Trigger on a parallel bus data value. Parallel bus can be from 1 to 16 bits in size. Binary and Hex radices are supported.
