My Leader audio generator doesn't do 100kHz.

Post a link to it.

I found 6 different "Leader" audio gens on the net and all go out to at
least 100kHz.


It's a LAG 120B and your right it's highest resolution is 1 Mhz.

Sorry. Never used it that high with amplifiers.

( I can hardly believe I am posting that .... )

One reason for having 100kHz or more available on an "Audio Generator" is to
enable the testing of audio filters that may have turn over frequencies at
say 22 kHz. To find the roll of slope, one needs to check the response for
several octaves above that frequency.

Another use is in testing the response of audio transformers - ie line,
mic or valve output. These often exhibit severe ringing at frequencies
between 25 kHz and 150kHz. This can often be eliminated with a suitable RC
damping network.

Audio gens also need to go down to 1 or 2 Hz as well - so one can check any
sub sonic filters included in amplifiers and other devices OR to force DC
and anti-thump protection relays in power amps to cycle to verify their
operation.

Many other good reasons exist too.
