"Threshold
high" and
"Threshold
low"
Upper and lower threshold levels. You can enter the values directly in
the fields.
"Find thresh-
olds"
Executes the measurement of reference levels and sets the thresh-
olds to the middle reference level of the measured amplitude.
Remote command:
BUS<m>:MILStd:THReshold:HIGH on page 1687
BUS<m>:MILStd:THReshold:LOW on page 1687
BUS<m>:MILStd:PRESet on page 1687
BUS<m>:SETReflevels on page 1548
Check min gap
Checks and sets a value for the intermessage gap between the last bit of a message
and the following command word sync. The time is measured between the mid bit zero
crossings. According to the standard, the minimum idle time is 4 μs.
The minimum gap time is relevant for protocol configuration and error trigger.
If "Check min gap" is enabled, the instrument detects the specified gap during decod-
ing. If the trigger type "Error condition" is selected in addition, the instrument triggers
when the gap is shorter then specified.
Remote command:
BUS<m>:MILStd:MINGap:BITS on page 1686
BUS<m>:MILStd:MINGap:SELect on page 1686
TRIGger<m>:MILStd:MINGap:BITS on page 1696
TRIGger<m>:MILStd:MINGap:SELect on page 1696
Check max response
Checks and sets a value for the maximum response time between the last bit of a word
and the following status word sync. The time is measured between the mid bit zero
crossings. According to the standard, the RT shall respond to a valid command word
within the time period of 4 to 12 μs.
The max response time is relevant for protocol configuration and error trigger.
If "Check max response" is enabled, the instrument detects the specified gap during
decoding. If the trigger type "Error condition" is selected in addition, the instrument trig-
gers when the response time is longer than specified.
Remote command:
BUS<m>:MILStd:MAXResponse:BITS on page 1686
BUS<m>:MILStd:MAXResponse:SELect on page 1686
TRIGger<m>:MILStd:MAXResponse:BITS on page 1695
TRIGger<m>:MILStd:MAXResponse:SELect on page 1695
