That does appear to be so. Without looking it up, I just had it fixed in my
head that it was around 100kHz. With the fact that it is a highly asymmetric
waveform, duty factor-wise, I guess that it's hard to quote it as an actual
frequency. It's sort of 100+ kHz 'width' pulses, repeated at a frequency of
2kHz ...

I have this meter:

and it outputs a 60 mVpp sine wave at 80 kHz. It works great.
