UART/RS232 Triggering and Serial Decode
•
Rx 1:Data
— For use when the device under test data words are 9 bits in
length including the alert bit (the 9th bit). Triggers only when the 9th (alert)
bit is 1. The specified data byte applies to the least significant 8 bits
(excludes the 9th (alert) bit).
•
Rx 0:Data
— For use when the device under test data words are 9 bits in
length including the alert bit (the 9th bit). Triggers only when the 9th (alert)
bit is 0. The specified data byte applies to the least significant 8 bits
(excludes the 9th (alert) bit).
•
Rx X:Data
— For use when the device under test data words are 9 bits in
length including the alert bit (the 9th bit). Triggers on a data byte that you
specify regardless of the value of the 9th (alert) bit. The specified data byte
applies to the least significant 8 bits (excludes the 9th (alert) bit).
•
Similar choices are available for Tx.
•
Rx or Tx Parity Error
— Triggers on a parity error based on the parity you have
set in the Bus Configuration Menu.
6
If you choose a trigger condition that includes "
Data
" in its description (for
example:
Rx Data
), then press the
Data is
softkey, and choose an equality
qualifier. You can choose equal to, not equal to, less than, or greater than a
specific data value.
7
Use the
Data
softkey to choose the data value for your trigger comparison. This
works in conjunction with the
Data is
softkey.
8
Optional: The
Burst
softkey lets you trigger on the Nth frame (1-4096) after an
idle time you select. All trigger conditions must be met for the trigger to occur.
9
If
Burst
is selected, an idle time (1 µs to 10 s) can be specified so that the
oscilloscope will look for a trigger condition only after the idle time has past.
Press the
Idle
softkey and rotate the Entry knob to set an idle time.
NOTE
If the setup does not produce a stable trigger, the UART/RS232 signals may be slow enough
that the oscilloscope is AutoTriggering. Press the
[Mode/Coupling]
key, then press the
Mode
softkey to set the trigger mode from
Auto
to
Normal
.
