Could the built in two tone generator be used as an input for this?
Now to download the latest manual and read about the "audio voltmeter"
I did not realize it had. ;)

I have the full range of filters, from 13 KHz to 200 Hz and found that there
isn't enough adjustment range to get them all exactly equalized. That is,
with the 2.7 KHz set to 0 (minimum possible) and the 200 Hz set to +8dB
(maximum possible) the 200 Hz was still 2 dB down from the 2.7KHz. So what
I did was to equalize the three filters that I use for CW (my primary mode
of operation) at one value and equalize the 13KHz and 2.7KHz filters at
another value (used for MW, SW listening, etc). This seems to work out
quite well in practice. Here is what I ended up with. The first column is
the variation in dB with the AGC off. The second is with the AGC on. I
used a signal generator and the K3 built-in audio voltmeter for the
measurement.
Filter w/o AGC w AGC
13 K -0.5 -0.1
2.7 K 0 0
1.0 K -2.1 -0.4
500 H -1.5 -0.3
200 H -2.0 -0.4
