The "BERT" analyzer function enables measuring the bit error rate across an HDMI
transmission path by sending defined bit patterns in the picture content. The measure-
ment can be selected only if the settings "Source" = "Intern" and "Pattern" = "BERT"
have been selected in the generator, otherwise a corresponding message appears.
An informative measurement result is present only if a device under test outputs the
received BERT pattern of the HDMI generator unchanged since the measurement
compares transmitted and received data patterns with each other.
The measurement result of the bit error analysis is displayed as percentage of defec-
tive bit patterns, based on the total number of patterns transmitted during the defined
measuring time.
SCPI command:
SENSe[1]:FUNCtion BERT
Meas Time
Duration of the BERT measurement. For a continuous measurement, the measure-
ment is restarted after the measuring time expires.
"Value " The BERT measurement is performed inside a predefined time which
has to be entered in the following parameter field.
Remote command:

5.34 Frequency, Phase and Group Delay Measurement
The frequency measurement and combined frequency/phase/group delay measure-
ment are performed upstream of the function-specific digital filters, but downstream of
the prefilter.
Freq Phase
Used to activate the frequency measurement (for the reference channel) and to select
the measured value for the other channels.
With 1-channel measurements, it is only possible to select the frequency measurement
here; measurement of the sampling frequency can be selected here in the digital ana-
lyzer.
