Here is a simple program that simply loads the VISA driver for the instrument at ASRL3::INSTR. It outputs *IDN to the instrument and then enters the response and stores it in a string variable. Finally it prints out the returned value in the string variable.
LOAD BIN "VISA;DEV ASRL3::INSTR ISC 7"
OUTPUT 7;"*IDN?";
ENTER 7;S$
PRINT "The connected device is: ",S$
END
An alternative to loading the driver in code is to use the Device Setup under the tools menu.
