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
Internal DC coupled
Trigger source Sensitivity
1 MΩ path (all models) For 1 mV/div to 4.98 mV/div; 0.75 div from DC to 50 MHz,
increasing to 1.3 div at rated bandwidth
50 Ω path (≤500 MHz models) For ≥5 mV/div; 0.4 div from DC to 50 MHz, increasing to 1 div
at rated bandwidth
50 Ω path (1 GHz models) 0.4 div from DC to 50 MHz, increasing to 1 div at rated
bandwidth
External
Trigger source
Sensitivity
Auxiliary Input 200 mV from DC to 50 MHz, increasing to 500 mV at rated
bandwidth
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 frequency readout Provides 6-digit frequency readout of triggerable events.
Trigger types
Edge Positive, negative, or either 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: 4 ns to 8 s. Or Trigger Delay by Events: 1 to 4,000,000 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.
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 active, Start of Frame, MOSI, MISO, or MOSI and MISO on SPI buses up to 50.0 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.
