SSSSSSSSSSSS SSSSSSSSSS SSSSSSS S SSS S SSSSS S
The time quality character, "Q", is one of the following characters:
Note: F8 does not display milliseconds, regardless of the format defined in F11.
Suppress the “DDD”, “HH”, “MM”, “SS”, “mmm”, and “Q” segments of F11 by placing an “X” (Shift-X) in
the leading position of any segment, followed by any placeholder characters, and the following
separator. For example, to suppress “DDD”, enter:
F11 X--:
To see the resulting change to F11, enter:
F11
F11, with “DDD” suppressed, responds:
F11 XDD:HH:MM:SS.mmmQ
With “DDD” suppressed, the output of F8 would look like this example:
:16:23:32
Ending a format string early (no “:” or “.” separator at the end) with a carriage return, enables the
remaining un-typed characters. This makes it easy to restore the default F11 formatting.
To return F11 to its default format, enter:
F11 D
To display the restored defaults, enter “F11” again. F11 responds:
F11 DDD:HH:MM:SS.mmmQ
The “DDD”, “HH”, “MM”, “SS”, “mmm”, and “Q” segments can not be replaced with characters, they can
only be suppressed.
The “:” and “.” separators can be replaced with ASCII characters or suppressed using “X”. For example,
to replace the separators with characters, enter:
F11 ---D--H--M--S
When you check the results by entering “F11”, F11 responds:
SPACE = Time error is less than time quality flag 1's threshold
. = Time error has exceeded time quality flag 1's threshold
* = Time error has exceeded time quality flag 2's threshold
# = Time error has exceeded time quality flag 3's threshold
? = Time error has exceeded time quality flag 4's threshold, or a reference source is unavailable
