[Milsurplus] Another ZA question

[Jack Antonio]

I have managed to acquire another piece of
the ZA ILS system, one that is not shown
or described in the manual I have.

The item is a CDE-60050 Test Oscillator.

Anyone have a manual or schematic of the device?

It appears that it is a buzzer type of
signal source, my guess is that it is
to provide a go/no-go indication rather
than a calibration source.

Thanks
