Note: The three DDS Sync Delay parameters are board specific delay line values that
are determined to make sure that all three DDSs are synchronized and should not be
changed!
Next the dependencies and Polarities of the service pulses has to be defined. There
are four programmable service pulses, and they are used to gate transmitters and pre-
amplifiers. For each pulse the HF pulse that it should be connected to, the polarity and a
pre- and/or post-delay (in multiples of 40 ns) can be defined. The default settings are:
Next, further down on the same
page, the frequency range has to
be defined. For 300 MHz this is:
