operation up 1 km (3,280 ft), and telephone modem operation over
any distance. HP Sales and Service offices can provide additional
information on the HP-IB extenders.
The codes next to the HP-IB connector, illustrated in Figure C-2,
describe the HP-IB electrical capabilities of the swept CW generator,
using IEEE Std. 488-1978 mnemonics (HP-IB, GP-IB, IEEE-488,
and IEC-625 are all electrically equivalent). Briefly, the mnemonics
translate as follows:
AH1
T6:
Source Handshake, complete capability.
Acceptor Handshake, complete capability.
Talker; capable of basic talker, serial poll, and
unaddress if MLA.
TEO
L4
Talker, Extended address; no capability.
Listener, capable of basic listener, and unaddress if
MTA.
LEO
Listener, Extended address; no capability.
Service Request, complete capability.
Remote Local, complete capability.
Parallel Poll, no capability.
DC1
Device Clear, complete capability.
Device Trigger, complete capability.
CO,
1,
2, 3, 28 Controller capability options; CO, no capabilities;
E l
Cl, system controller; C2, send IFC and take charge;
C3,
send REN; C28, send I. F. messages.
Electrical specification indicating open collector
outputs.
These codes are described completely in the
IEEE Std 488-1978
document, published by The Institute of Electrical and Electronic
Engineers, Inc., 345 East 47th Street, New York, New York 11017.
SOURCE MODULE INTERFACE sends and receives digital and
analog signals to and from an HP
millimeter-wave
source module. With the source module connected, the swept CW
generator assumes the characteristics of the source module. Refer to
Leveling Point Module for more information.
