Most ANAs I've worked with don't go down to low enough frequencies, but,
then, I work in mostly microwave stuff, to the test equipment I'm using
follows the certain arrogance to microwave measurement tool design... oh,
100 kHz, that's basically DC.  I've been contemplating building a HF
network analyzer (say, 100kHz to 30 MHz), using a variant of the old 3 volt
meter technique.  

An impedance bridge might be a better approach. The newest boxes from
Agilent are pretty fancy, and will do stepped frequency measurements,
digitizing with many bit A/Ds, etc. 

Or, hit the secondary with an impulse or step, and measure the time domain
response, then FFT to get frequency domain.  This is what Terry and Paul
were doing a couple months back.
