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.
