Quality tracks (binary tracks)
All tracks including quality tracks are recorded by SIMEAS R-PMU, evaluated by OSCOP P and
presented in the form of a diagram with eight tracks (one track not used). Depending on the
status, a bar (logical 1) or no bar (logical 0) is recorded.
The following status information is displayed for the recording period of time that is set on
OSCOP P:
‰
Reference frequency invalid:
The reference is invalid (insufficient signal quality), the
measured values based on the reference frequency are also invalid.
0: Reference frequency valid
1: Reference frequency invalid
‰
Frequency group 1 invalid:
The frequency measurement of group 1 of the evaluated DAU
is not possible or faulty, e. g., because of missing signals.
0: Frequency measurement valid
1: Frequency measurement invalid
‰
Frequency group 2 invalid:
The frequency measurement of group 2 of the evaluated DAU
is not possible or faulty, e. g., because of missing signals.
0: Frequency measurement valid
1: Frequency measurement invalid
‰
DAU not synchronized:
Synchronization of the evaluated DAU is not (yet) possible
because, for example, the system has not (yet) completed the transient recovery phase after
the GPS signal has been cut-off and returned, or after the SIMEAS R has been restarted.
0: Time synchronized in DAU
1: Time not synchronized in DAU
‰
CPU not synchronized:
The CPU is not or not yet synchronized and is thus free-running
based on RTC (DCF77 signal provided only approx. 2 minutes after start-up).
0: Time synchronized in CPU
1: Time not synchronized in CPU
‰
TAR recording active:
displays the current recording of the TAR
0: inactive: no recording
1: active: recording active
‰
TPR recording active:
displays the current recording of the TPR
0: inactive: no recording
1: active: recording active
