Hi Miguel,
mike mentioned that this is for an 30.5GHz application?
If it is for the Government Ka-band Terminal application then you may not be
able to use Trimble for that. They apparently cannot meet the spec due to
crystal jumps on their units.
Sorry for the shameless promotion, but we have a product that is qualified
to meet that spec. Contact me offline if you are interested.
bye,
Said

Hi group!
I need some opinions, counsel, help, whatever you can send my way:
I need to maintain the Mini-T within 20 Hz p-p in a 24 h period. I use
T=450 and all is well until the thing starts to lose satellites one by
one and goes into holdover and after a while, the VCO voltage jumps to
the start value and with it the frequency (up to -150Hz).
The antenna is not in a good place and it can't be moved, but if I
restart the Mini-T, all satellites that were grayed out come alive and
strong. Any clues?
Thanks,
Miguel
