Addressing the
Amplifier
The Agilent E1446A Summing Amplifier/DAC can be addressed by an
external controller or by an embedded controller. This section describes
how to address the amplifier using an external controller with the
Agilent E1445A AFG, with the Agilent E1405/06 Command Module, and
with an embedded controller.
Using an External
Controller
The Agilent E1446A can be programmed from an external controller via the
Agilent E1445A AFG or the Agilent E1405/06 Command Module. In an
Agilent VXIbus system using an external controller, the amplifier is located
by an (GPIB) address which consists of an interface select code, a primary
GPIB address, and a secondary GPIB address:
Interface Select Code: Determined by the address of the GPIB interface
card in the controller. For most Agilent Technologies controllers, this card
has a factory set address of 7.
Primary GPIB Address: Determined by the address of the GPIB port on
the Agilent E1405 Command Module. Valid addresses for the Command
Module are 0 to 30. The Command Module has a factory set address of 9.
