FUNCTION 05 - TIME QUALITY ENABLE/SETUP
3.32.1
Use function F05 to enable or disable the time quality indicators or to set the four worst-
case-error thresholds. The Serial I/O output string indicates the time quality. Refer to
"SERIAL I/O FUNCTION F08 - CONTINUOUS TIME ONCE PER SECOND" for a
description of the time quality indication in the Serial I/O time output string. As shipped
the time quality indicators are enabled and the thresholds are set to 10000ns, 100000ns,
1000000ns and 10000000ns. The unit will retain the values in use at power-down and
use them for subsequent power-ups.
3.32.2
To determine if the indicators are enabled and what the thresholds are, send F05<CR>
to the Serial I/O port. The port will respond with the ASCII character string
F05<SEP><STATE><SEP><FLAG><SEP><FLAG><SEP><FLAG><SEP>
<FLAG><LT>
where
F
= SCII character F.
05
= function number.
<SEP>
= one or more separator characters: either space,
comma or tab.
<STATE>
= ON or OFF.
<FLAG>
= one error threshold in nanoseconds, 1 to 11 digits
with or without leading zeros.
<LT>
= line terminator, either a carriage return and line
feed for output strings or a carriage return only for
input strings.
Sample request:
F05<CR>
Response:
F05 ON 00000000100 00000001000 00000010000
00000020000
3.32.3
To enable, disable or set the thresholds of the time quality indicators send a character
string with the following format:
Sample:
F05 ON 00000000100 00000001000 00000010000
00000020000
Response: OK<CR><LF>
3.32.4
Acceptable threshold value range: 00000000010ns to 40000000000ns.
Sample entry:
F05 ON 100 200 500 1000
Response:
OK<CR><LF>
3.32.5
Note that although leading zeros are not required for data entry they will be included in
any data response.

FUNCTION 08 - CONTINUOUS TIME ONCE PER SECOND ENABLE
3.33.1
Internal time will output once per second at the Serial I/O port if command string
F08<CR> is sent to the port. Time-of-year will output once per second after time input
via function F03. Character transmission is continuous with the end of the stop bit of one
character coinciding with the beginning of the start bit of the next character. The time
