manually, press the Read device response button. If you uncheck the Auto
Query button or if your query does not contain a question mark, you have to
do a manual read after each query. If you do not read a response from a device
and then send it another command or if you attempt to read when the device
has nothing to output, you will generate a device query error in an IEEE-488.2
device. A read that does not get a response will produce a timeout error on the
VXI11_kybd. (See Table 3-6 for a complete list or ICS's VXI-11 Errors.)
The Interface Command buttons on the right let you send commands to a GPIB
Controller (like ICS's Model 8065) and do not apply to the 8099.
The Instrument Command buttons on the right let you Lock and Unlock the
instrument. Locking an instrument prevents other clients from changing its
status or giving it new commands while you are using it to perform an operation.
Always Unlock the instrument when done with it. When the Auto Lock check
box is checked, the VXI11_kybd program automatically locks the instrument
when sending it a command and unlocks it when the command has been com-
pleted or when it has received a response to a query. A Red ‘Locked’ message
is visible when the instrument is locked.
The Device Trigger and Device Clear buttons send the corresponding GPIB
commands to the instrument. The Serial Poll button reads the instruments Status
Register and displays the results in the Device Response window.
Use the Help button in the upper right hand corner to access the VXI11_kybd
Help File.
