[Discuss-gnuradio] Tune time

[David Evans]

Hi,

Just a few general querys...

How long does it take for an RFX card to tune and lock to a frequency, once a 
set_freq command is issued? 
Does it matter if the steps are small or large, ie a greater swing on the VCO?
Is there a way to tell if/when the VCO is locked, ie its tuned (could I monitor 
it via the fpga gpio)?
Is there a way to tell if the frequency reference is locked to an external 
reference (could I monitor it via the fpga gpio)?

Regards,
Dave
