Re: What accessories do I need for a TinySA Ultra?

Yes, I have one generator that goes to ?Hz.? But I'm not a typical ham by any means!? If you build yourself a seismometer, you're in the mHz region.

Hate to burst your bubble Dave, but the HP-3561A , in their
documentation, refers to the low frequency coverage (micro Hz) as
uHz, and how about kHz. So, yeah, mHz for "mili Hz" works for me
but hey I'm only a retired technician. BTW electron flow is from
(-) negative to (+) positive, but the engineers I worked with
called it "hole flow". ??? I guess they stand on an overhead
bridge and watch the spaces going the opposite way than the cars.

Yea, Don, get the newbies to
use proper abbreviations!? I've called it out many times, but
it seems to fall on deaf ears and clearly never reaches the
gray matter.? What really gets my goat is "mhz".? What is
mhz?? MilliHertz?? Nothing the typical amateur deals with
delves into the milliHertz range!? Further the proper
abbreviation for Hertz is Hz, not hz!? Should I give up?

All references when not given are 0db = 1w
My observation is that very few people use units of dbW even
when working at high power, dbm (relative to 1 milliwatt)
being far more common.?
If a colleague started using dBW I would ask them why as
I see no good reason for it, it is likely to cause
confusion.? Like 1000X level confusion.
?
In the RF world, if something is written as "xdB" it is
NOT a power level, it is a power ratio, or actually 10log of
that ratio.?
?
The TinySA power specs all use dBm AFAIK.
