Hi,
Uh, yes, sort of...GPIB only...note the 2145 is a R3030A, and thus has RS449
control with a different protocol. I've been fooling around with National
Instruments Labview 7.0. The Cubics are a bit trickier than WJ to control
because Cubic makes use of the service request and serial poll
functions...this allegedly speeds up a system full of Cubic radios if the
controller beats the receiver by asking for data or ack before receiver has
processed the command. The controller, rather than wait, can run on to the
next receiver, etc, and return when the service request is detected ... the
receiver will generate a service request when its response data is ready to
read in the transmit buffer. I say alleged, because I'll likely never
really stress a system.
Watkins Johnson, on the other hand, can take a command, execute it, and
acknowledge...just don't be too early with the controller or at least have a
trap if you are early...something that brings the controller back after a
suitable period. The WJ's, I think, can be set up as poll-reactive, but
then they visibly slow down.
One is easier than the other to write, but needs handwritten response
analysis rather than the built in GPIB functionality.
Unfortunately, unless I buy the application generator software, my
rudimentary routines are not portable.
regards
John Collins
