The BER measurement shown by default (when PRN-23 BER option from Preferences menu is set to OFF)
yields an estimated value calculated using the MER measurement. In order to obtain a more accurate BER
measurement value, the PRN-23 BER option from Preferences menu must be set to ON and a PRN-23 signal
pattern must be used through the RF signal input [30].
If the input signal is like PRN-23 or a video signal, the BER and VBER measurement are considered as
acceptable when BER/VBER
taken as reference measurement.
