$AA0L
Name: Read Minimum Input Signal Width at Low Level.
Description: Read the minimum input signal width at low level for a
specified counter/frequency module to filter noise.
Syntax: $AA0L(cr)
$ is a delimiter character.
AA (range 00-FF) represents the 2-character hexadecimal
address of the counter/frequency module that you want to
interrogate.
0H identifies the Read Minimum Input Signal Width at Low
Level command
(cr) is the terminating character, carriage return (0Dh)
Response: !AA(data)(cr) if the command is valid.
?AA(cr) if an invalid operation was entered.
There is no response if the module detects a syntax or commu-

(data) is the minimum width at low level. The unit is µsec
(microsecond) and its resolution is 1 µsec. The format is a five
digit integer that ranges from 2 µsec to 65535 µsec.
(cr) is the terminating character, carriage return (0Dh).
Example: command: $050L(cr)
response: !0500084(cr)
The command requests the counter/frequency module at
address 05 to read its minimum input signal width at low level.
The addressed module replies that its minimum input signal
width at low level is 84 µsec.
