Thanks Andy.
I expected this to be the case, but hope springs eternal!
OK, back to the drawing board.

It 'would' be possible if you :-
1) Know the command's needed to control the sig. gen That will be
in the equipment manual
2) Have an IEE488 interface on your PC, or a USB/IEE488 or whatever,
adapter box
3) Manage to get the author of the QRSS software to include a driver
to send commands on the IEE488 interface to control the amplitude
1) is just reference material 2) costs a few tens of pounds, 3) is
going to be well-nigh impossible
So, its almost certainly not-on
I assume you were hoping for a simple on/off pin to be available on
the connector. IEE488, otherwise known in HP's implementation as
HPIB, is an 8 bit wide, rather ancient bidirectional bus for computer
control of test equipment. In spite of its age - designed in the late
1960's or thereabouts - due to its universality and standardisation of
connectionsand protocol (though not commands) its still alive today.
USB and COM port to IEE488 interfaces are readily available.
