314 Agilent InfiniiVision 5000 Series Oscilloscopes Programmer's Reference
3Commands by Subsystem
• CAN (Controller Area Network) triggering will trigger on CAN version
2.0A and 2.0B signals. Setup consists of connecting the oscilloscope to a
CAN signal. Baud rate, signal source, and signal polarity, and type of
data to trigger on can be specified. With the automotive CAN and LIN
serial decode option (Option ASM), you can also trigger on CAN data
and identifier patterns, set the bit sample point, and have the module
send an acknowledge to the bus when it receives a valid message.
• Edge triggering identifies a trigger by looking for a specified slope and
voltage level on a waveform.
•Pulse width triggering (:TRIGger:GLITch commands) sets the
oscilloscope to trigger on a positive pulse or on a negative pulse of a
specified width.
•Pattern triggering identifies a trigger condition by looking for a
specified pattern. This pattern is a logical AND combination of the
channels.
• Duration triggering lets you define a pattern, then trigger on a
specified time duration.
• IIC (Inter- IC bus) triggering consists of connecting the oscilloscope to
the serial data (SDA) line and the serial clock (SCL) line, then
triggering on a stop/start condition, a restart, a missing acknowledge, or
on a read/write frame with a specific device address and data value.
• LIN (Local Interconnect Network) triggering will trigger on LIN sync
break at the beginning of a message frame. With the automotive CAN
and LIN serial decode option (Option ASM), you can also trigger on
Frame IDs.
• SPI (Serial Peripheral Interface) triggering consists of connecting the
oscilloscope to a clock, data, and framing signal. You can then trigger
on a data pattern during a specific framing period. The serial data
string can be specified to be from 4 to 32 bits long.
•TV triggering is used to capture the complicated waveforms of
television equipment. The trigger circuitry detects the vertical and
horizontal interval of the waveform and produces triggers based on the
TV trigger settings you selected. TV triggering requires greater than º
division of sync amplitude with any analog channel as the trigger
source.
• UART/RS- 232 triggering (with Option 232) lets you trigger on RS- 232
serial data.
Reporting the Setup
NOTE The CAN and LIN serial decode option (Option ASM) replaces the functionality that was
available with the N2758A CAN trigger module for the 54620/54640 Series oscilloscopes.
