Chuck,
Most stock chokes are measured at frequencies around 1 and 10 kHz using a
precision LCR (bridge) meter. I have both the analog and digital bridges here
and use both. There are some LCR meters by HP and a few others which can
measure up to 10 MHz. Most all stock coils though like Ohmite are measured at
around 1 to 10 kHz. The three top manufacturers of LCR meters is HP, ESI, and
GenRad.
Best,
Will
