5.5.2 SendCmd Method
Method:
SendCmd ( command , acknowledge )
Parameter:
Command [in]
Acknowledge [out]
String
String
Return value:
Result value of command (see command description in chapter 4)
Remarks:
Same as above ‘Send’ method, but additional parameter ‘acknowledge’
contains the ‘reply’ of the tuner send after receiving ‘command’. Use this
method to send commands such as ‘dir’ that have a large string reply from the
tuner.
Examples:
iTuner.SendCmd(‘dir’, directory)
Parameter ‘directory’ contains reply of
tuner to ‘dir’ command
5.5.3 OPC Method
Method:
OPC (maxWait )
Parameter:
maxWait [in]
Long, in seconds
Return value:
0 -> task has completed
<0 -> timed out before completion
Remarks:
Calling OPC halts your application until the tuner has completed all current
tasks, such as initializing or tuning to a new probe position.
OPC internally calls the ‘STATUS?” command, and returns when either
 STATUS? returns 0, or
 maxWait seconds have elapsed.
Use a maxWait value that correspond to your tuner, thus allowing sufficient
time for the tuner to complete its tuning operations.
