Configuration Functions - Promax MO-160 Manual Del Usuario

These following two parameters set the amount of errors we inject into the
modulator chain:
CBER Value: Channel Bit-Error Ratio to inject at the input of the mapper to
constellation points. This yields a non-zero BER before the Viterbi decoder
(values from 7.6E-6 to 1.2E-1).
VBER Value: Viterbi BER to inject at the input to the convolutional encoder
so that a non-zero BER is obtained at the output of the Viterbi decoder
(values from 3.7E-9 to 6.2E-2).

4.8 CONFIGURATION functions

Under this menu tree there is a collection of functions related to the configuration
and setup of the whole instrument.
Save to Memory: The MO-160 has a number of configuration memories that
allow to store the modulator parameters as well as the RF frequency and
level.
To store the current configuration, turn the encoder to select the desired memory
number (from 0 to 10). Press the encoder key to confirm the storing action. Press the
MENU key to cancel the action.
This function, as well as the recall option explained hereafter, automatically
increments the memory number, to allow to easily store and recall the contents of
consecutive memories.
Load from Memory: This is the counterpart function of the previous one.
Selecting the desired memory number, a complete equipment configuration
can be loaded.
Channel Plan: Use this function to choose among the channel plans included
in the MO-160. Currently, the available channel plans (an ordered list of
channel frequencies) have been translated from the standard analogue
channel plans. A complete list of all channel plans has been included at the
end of this document (see Appendix A).
The selections displayed using the rotary encoder are:
