24 Getting Started
Operating the Instrument
An Agilent 3499A/B/C Switch/Control System can be easily operated from
the front-panel, or programmed with SCPI (in SCPI mode) or 3488A (in
3488A mode) commands over the remote interface.
The following sections are only intended to show some basic front-panel
operation. For more information about the front panel operation, refer to
Chapter 3 “Front-Panel Operation” starting from Page 31.
Channel
Addressing
In Agilent 3499A/B/C Switch/Control System, a channel refers to an
individual relay on a switching module, or an individual bit/port on a digital
I/O module. The channel address is in the form of snn, where s represents
slot number. Slot 0 refers to the mainframe controller board, s = 1-2 (for an
Agilent 3499B), s = 1-5 (for an Agilent 3499A) or s = 1-9 (for an Agilent
3499C); nn represents channel number (module dependent, see Table 2-1).
