Easy Ways to Control Instruments
Using a Panel Driver
Using a Panel Driver
These exercises use the HP 3325B Function Generator as the example. The
principles are the same in using any VEE panel driver. By using a panel
driver instead of programming an instrument directly, you save time
developing and modifying programs. Changes in the instrument settings are
made through menu selections or by editing fields in dialog boxes. If the
instrument is connected and
Live Mode is ON, the changes you make will
register on the instrument.
To use a panel driver in a program, add inputs and/or outputs as needed and
connect the panel driver to other objects. You can use several instances of
the same driver in a program to set the instrument to different states. In VEE,
you can iconize a panel driver to save space, or use the open view to display
the instrument settings. You can also change settings while a program is
running.
