Datasheet

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 analog channel input For 1 mV/div to 4.98 mV/div; 0.75 div from DC to 50 MHz,

increasing to 1.3 div at instrument bandwidth

≥ 5mV/div: 0.40 div from DC to 50 MHz

Aux In (External); available on two-channel instruments only 200 mV from DC to 50 MHz, increasing to 500 mV at 200 M

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 In (External) ±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. 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 4,000,000 events. Not available when “Either” edge is

selected.

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.

Setup and hold trigger type

Description

Setup Time Range -0.5 ns to 1.024 ms

Hold Time Range 1.0 ns to 1.024 ms

Setup + Hold Time Range 0.5 ns to 2.048 ms

Rise/Fall Time Trigger on pulse edge rates that are faster or slower than specified. Slope may be positive, negative, or either and time range is

4.0 ns to 8 s.

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

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

Custom bi-level and tri-level sync video standards.

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 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.
