CONVERTER CODES
3-57,
When power is applied to the 5355A certain codes are displayed to indicate which
Frequency Converter Head is installed, as follows:
5356B (1.5—26,5 GHz)
5356B Option 001 (18-26.5 GHz)
5356C (1.5—40 GHz;
5356C Option 001 (26.5-40 GHz)

The capability of a device connected to the HP-IB is specified by the interface functions
that it has. Table 3-6 lists the interface functions included in the 5355A. The "Interface Function
Subset identifier" refers to the particular capability of the interface function as listed in
Appendix C of IEEE Standard 488-1975.

INTERFACE FUNCTION
SUBSET IDENTIFIER
INTERFACE FUNCTION DESCRIPTION
5H0
No source handshake capability.
AH1
Complete acceptor handshake capability.
T0, TE0
No talker (no basic talker, no serial poll, no talk only mode, does not
unaddress to talk if addressed to listen).
L2, LE0
Listener (basic listener, no listen only mode, does not unaddress to listen
if addressed to talk).
SR0
No service request capability.
RL1
No complete remote/local capability (with local lockout).
PP0
No parallel poll capability.
DC1
Device clear capability (presets to power-up control states),
DTI
Device trigger capability.
C0
No controller capability.
El
1 Unit Bus Load.
NOTE:
Interface functions provide the means for a device to receive,
process and send messages over the bus.
3-61.
Bus messages are of 12 types. Table 3-7 lists each bus message, a brief description of the
message, and the response of the 5355A/5345A to the message. The last column shows typical
examples of how to send/receive each message using the 9825A computing controller. For
complete details on sending bus messages using the 9825A refer to the "9825A Extended I/O
Programming Manual" (Part Number 09825-90025).
