General protocol : TIME MEASURING


 

The time measuring function makes possible the measurement of the received signals independently of the protocol for the analysis of seriell-digital processes on the transmission lines ( Pulse width measuring ) or the received times of the signals and the physical level for the investigation of processing times ( Slopes )

Parameterization Pulse width measuring :

The measuring of signal times can be set for pulse-duration modulated or pulse-code modulated signals.

 

Pulse-Duration-Modulation

The channel parameterized with this function measures the length of signals in the mode "duration of pulse modulation", independently of a particular telegram format. The parameterization does not differ from the one of the protocols except for the entry into the protocol-file, because in this case recording is not only restricted on errors.

Pulse-Code-Modulation

The channel parameterized with this function measures the length of signals in the mode "pulse code modulation", independently of a particular protocol format. The parameterization does not differ from the one of the protocols except for the entry into the protocol file, because in this case recording is not only restricted on errors.

Parameterization slope time measuring :

If a channel is parameterized by means of this function, only the received times of the signals and the physical level are recorded. The output in the protocol-file takes place unrestricted.
