Figure 1-2. E1445A Logical Address and Servant Area Switch Location
Addressing the AFG
Devices in the C-size mainframe and in the servant area of the
Agilent E1406A Command Module are located by an GPIB address. The
(External Controller
GPIB address is a combination of the controller's interface select code, the
and PC)
command module's primary GPIB address, and the device's secondary
GPIB address. An address in this form in a BASIC statement appears as:
OUTPUT 70910;"SOUR:ROSC:SOUR INT1;:TRIG:STAR:SOUR INT1"
Interface Select Code (7): This code is determined by the address of the
GPIB interface card in the controller. In most Agilent controllers, this card
has a factory set address of 7, including the Agilent 82340/82341 GPIB
Interface Card (this card was used with an HP Vectra PC to create the
Visual BASIC and Visual C/C++ example programs).
Primary GPIB Address (09): This is the address of the GPIB port on the
command module. Valid addresses are 0 to 30. The module has a factory
set address of 9.
Secondary GPIB Address (10): This address is derived from the logical
address of the device (AFG) by dividing the logical address by 8. Thus, for
the Agilent E1445A AFG factory set logical address of 80, the secondary
address is 10.
