HP-IB Capab~l~ty
HP 3326A HP-IS CAPA
The HP 33268 interfaces to the HP-IB as defined by IEEE Standard 488-1 978. The in-
terface functional subset which the HP 3326A implements is specified in Figure 2-2.
HP-IS INTERFACE MANAGEMENT LINES
Five lines in the HP-IB manage the orderly flow of information across the HP-IB. Figure
2-3 describes the lines used in managing the HP-IB.
TALKlLlSTEN ADDRESSES
Each HP-IB device has at least one talk, and one listen address (unless the device is
totally transparent, or a talk only or listen only device). Device addresses are used by
the active controller in the COMMAND MODE (ATN true) to specify the talker (via a
talk address) and the listener (via listen addresses). There may be only one talker ad-
dressed by the controller to talk at any time.
