"Find thresholds"
Executes the measurement of reference levels and sets the thresholds to the middle
reference level of the measured amplitude.
Remote command:
BUS<m>:ARINc:THReshold:HIGH on page 1713
BUS<m>:ARINc:THReshold:LOW on page 1713
BUS<m>:ARINc:PRESet on page 1713
BUS<m>:SETReflevels on page 1548
Bit Rate
Selects the number of transmitted bits per second. The value can be set to high speed
(100 kbps) or low speed (12.0- 14.5 kbps).
Remote command:
BUS<m>:ARINc:BRValue on page 1711
BUS<m>:ARINc:BRMode on page 1711
Timing: Min gap, Max gap
Defines the idle time between two words, which is needed for word synchronization.
The beginning of the first bit after the gap marks the start of a new word.
You can define a minimum idle time "Min gap", and/or a maximum time "Max gap". The
standard defines a minimum of 4-bit times to separate two subsequent words.
Timing settings are relevant for protocol configuration and error trigger.
If "Min gap" and/or "Max gap" are enabled, the instrument detects the specified gaps
during decoding. If the trigger type "Error condition" is selected in addition, the instru-
ment triggers when the gap is shorter or longer than the specified gaps, respectively.
