ASSIGN @PS TO 70600

! Statement for Agilent BASIC Interface

1040

!Linked address 1. The power supply will respond if it is set to address .1 and is serially connected to a

 

supply at direct address 6.0

 

1050

PS=706.01

!Agilent 82335A Interface

1090

ASSIGN @PS TO 706.01

!Agilent BASIC Interface

For systems using the National Instruments DOS driver, the address is specified in the software configuration program (IBCONFIG.EXE) and assigned a symbolic name. The address then is referenced only by this name within the application program (see the National Instruments GP-IB documentation).
