VRF - Programming PassThru instruments with Direct IO

Question asked by VRFuser on Nov 4, 1997

     Ken,
    
     We send passthru commands to a HP8350b sweep oscillator, via a
     HP8757c, using direct i/o.  It works fine.
    
     In instrument manager I have something like:
    
     HP8757(@716)
     HP8350(@717)
    
     ...where 716 is the analyzer's regular address and 717 is the passthru
     address.  Note that I've used two different instrument names to make
     things less confusing.
    
     Simply program the analyzer using the former object, and the source
     using the latter.
    
     Hope this helps,

     Is it possible to program the source for an HP8757D scalar analyzer
     using Direct IO?
    
     Do you have to set up a scalar analyzer object in the Instrument
     manager at the passthru address and send the pass thru commands to
     that object?
    
     ie.
    
     HP8757(@716) for regular commands
     HP8757(@717) for pass thru commands
    
    
     Or can you only do pass thru commands via the panel driver or
     component driver?
    
    
     Thanks,
    
     Ken Larson
