It may  be possible ,  IEEE   cards for PC   are available  on ebay , 
originally it  was  complimentary to  HP basic, and  used the HP range of 
PC's with  addressed  card slots .. allowed  you  to  construct a  automated 
system from  discrete  items of  equipment ..HP unless you  hacked your  own 
control  card , going  back to 1972 is the  first  I remember , linked to 
HP  neon nixie  tubed  DVM and Counter / timer , with a IEEE>GEC  re-hash 
on the back ,

The IEEE   drivers  (Instrument set up frame)  should be downloadable  from 
the  R&S  web  site , as to qrss  , you would need  to  interface  with the 
HP-basic control  programme , read a  switch/button or line voltage , I dont 
think it would be simple  to  bridge .but  you could  set  up a  series of 
carrier on.off  timed commands in basic , but  its a  big  task  for a  task 
that is  covered  by other  software

unless  for  example the  LCD  display has  finally  washed out  and the 
IEEE is the  only  way to  set the  instrument  up , in which case its 
quite  simple , just  run the  set-up  frame  and control  from the  pc in 
remote  mode , a useful  second life !
