button to activate this link. Other options are GPIB, RS232 and VXI
but they should be disabled for now. If you press the All Platforms
button, then the program will attempt to connect every possible link,
which usually takes much longer.
The On Instrument Activation group lets you select the opening
scenario for the instrument. The various options are described below:
Reset Instrument and Panels – will reset the generator and the
control panels to factory default values. Parameter defaults are listed
in Chapter 4 of this manual.
Update Panels – can be used in case you had to leave the program
but left the generator still operating. The update Panels option will
query instrument setting and will update the control panels
accordingly. Note that waveforms cannot be read from the instrument
so only control panels will be affected from this operation. The Update
Panels option is useless if you powered down the host computer.
Update Instrument – can be used every time you invoke
ArbConnection. Every time you exit ArbConnection, an image of the
last control panel setting is automatically stored on your hard drive so
the next time you invoke the program the control panels are updated
from this image. When you use the Update Instrument option, the
instrument will update its operational settings and parameter values
only but will not download waveforms.
Refresh Communications – will activate the Autodetect engine and
will attempt to reconnect all devices that respond to ArbConnection
calls. The use of this option is normally not required except in isolated
incidents that you suspect that ArbConnection has not detected all
instruments that are present in the chassis.
Work Offline – will let you use ArbConnection without actually
controlling or having an active instrument plugged in. This option also
lets you prepare and save control panel settings for later use.
Communicate Only – will make the connection between
ArbConnection and the instrument but will not synchronize between
the two. You can use this option if you already modified instrument
parameters but had to leave the program for a different application,
otherwise, this option It is not recommended for normal use.
There are two more options to select from this dialog box. The Start
Communications with:
First Found instrument – will start ArbConnection communication
with the first instrument that was detected. If there are more than one
instrument plugged into the chassis, you may want to select the next
