tc output active
= “
yes
“, if the time code generator is ready to output time code of
the selected formats (LTC, D-VITC, ATC). After power has turned on,
all outputs will be inactive firstly. Outputs become active if the
frequency and phase synchronization has been reached, and if
during the REAL

TIME method of operation an update with the real

time reference was successful, but not later than 100 seconds.

= “
yes
“, if the phase and frequency synchronisation is currently in a
“lock” state; = “
no

“lock” state once before; = “

freq divider, current
Indicates the current tuning of the internal oscillator.
freq divider, nominal
Indicates the nominal tuning value of the internal oscillator.
external sync
Indicates the reference tuning value of the internal oscillator. This
value has been gained from the connected sync signal.
errors no sync
Counter of failures of the connected sync signal, 0
–
9999.
errors sync disturbances
Counter of disturbances of the connected sync signal, 0
–
9999.
Both counters reset to zero changing the operating mode of the time
code generator or changing the selection of the sync signal.
pps
–
v1 delay (us)
The difference between PPS and video signal is measured. This
enables to verify that the video sync generator (SPG) is locked to a
real
–
time reference in a 625/50 (PAL) television system. With a
constant difference the video signal has no drift against the real
–
time. With difference equal or near 0 even the video phase is
aligned with the PPS signal.
time
The currently generated time, HH:M:SS. This time display should not
be used for a precise comparison of time, because this display may
be delayed up to two seconds due to internal data transfer.
user
The currently generated user data.
