Max Response ← Error Condition
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 "Max Response" 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 response time is longer than specified.

each identifier:
●
"RTA": hexadecimal remote terminal address value
●
"Sub Addr": hexadecimal sub address value
●
"Sub Address Label Name": the label name corresponding to the value of the sub-
address.
●
"Symbolic label": symbolic name of addressed device, specifying the device func-
tion, and the label of the sub address.
