[Elecraft] S-Meter Calibration

[Doug Kingston]

I have access to signal generator similar to this (
http://www.circuitspecialists.com/sdg830.html), but its minimum output is
4mv.  The calibration calls for 50uV of signal.
It looks like I could set the output to 40mv (I don't like working at the
bottom of the range), and then attenuate the output with 3 20db
attenudators (e.g.
http://www.fairviewmicrowave.com/20db-fixed-attenuator-bnc-male-bnc-female-0.5-watts-sa01b-20-p.aspx)
in series which would reduce the voltage by a factor of 1000.  Does this
sound like a viable plan?
