Chapter 3 System Overview

Mainframes Overview

Three mainframes are available:

The 3499C is designed to accommodate multiple width plug-in modules and has 9 logical

slots but 14 mechanical slots. Slots 1 through 6 are 1-slot wide, slot 7 is 2-slots wide, and

slots 8 and 9 are each 3-slots wide. See the figure on page 7 for more information.

All mainframes can be either operated from the front-panel or

programed over a remote interface (GPIB or RS-232).

The mainframes can be operated in either of two system modes: SCPI

mode or 3488A mode. The SCPI mode allows the full realization of

performance potentials and advanced features, such as parallel

operation of multiple relays on multiple modules. The 3488A mode is

included for backward compatibility with the legacy Agilent 3488A

system. This manual documents the 3488 mode of operation.

For information about the SCPI programming mode please refer to the

User’s Manual shipped with your Agilent 3499A/B/C, or visit
