It seems that when I create a signal source block and try and view the
signal on a waterfall plot or FFT plot, I can not increase the signal by
a granularity of 1 Hz at higher starting frequencies.
Example:
If I create a signal source block with a starting frequency of 1.2 GHz,
and in the block have a variable slider added to the frequency (assume
the variable can slide between 0 and 1000), i must move the slider 120
or more steps before the signal shifts on the waterfall plot with a gap
of 120 or more hz.
Is there a way to move the signal by 1 hz regardless of how high or low
the signal source frequency is?

Using a signal source to produce a synthetic signal at 1.7GHz is simply
not going to work, unless your sample-rate is 3.4GHz, which seems
rather unlikely.
Normally in Gnu Radio, signals are represented in complex-baseband,
leaving the hardware to move this up/down to the desired "on air"
frequency.
Not sure what you're trying to accomplish, perhaps you could share a
high-level overview?
