5.4.9 Pattern Ignore
Bit sequences of 32 bits or more with only "1" or "0", which some mobile radio stand-
ards provide instead of frame data when faulty frames are detected, can also be exclu-
ded from the measurement using the "Pattern Ignore" function (see figure).
Figure 5-6: Example of functionality of Pattern Ignore: 50 bits were set to "0" by the DUT. These 50
bits plus the preceding "0" are ignored in the bit error rate measurement.
5.4.10 Bit Error Rate Menu
The "Bit Error Rate" menu for configuring the bit error rate measurement is called
either in the "BERT" function block or via the MENU button under "BERT"
The top section of the "Bit Error Rate" menu is used to switch on the bit error rate mea-
surement and display the results and current status of the measurement.
The "Configuration" section is used to select the type of measurement the data source
and the termination criteria.
