Model 4262A
3-60. OPTION 101: HP-IB.
3-61. The 4262A Option 101 provides interface
capabilities in accordance with IEEE-STD-488-
1975 recommendations.
3-62. Connection to HP-IB Controller: The
4262A Option 101 can be connected to an HP-IB
Controller (HP calculator) via HP-IB digital bus
connector on the rear panel of the 4262A and the
bus connector of the Bus I/O card installed in
calculator.
3-63. HP-IB Status Indicator: The four LED
lamps of the HP-IB Status Indicator (located below
the LCR display) show which HP-IB condition the
4262A is in:
SRQ: SRQ signal put on HP-IB lihe from
4262A. See paragraph 3-70 for details.
LISTEN: 4262a is set to listen. See paragraph
3-69 for details.
TALK: The 4262A is set to talk. See
paragraph 3-67 for details.
Remote: The 4262A is remotely controlled.
See paragraph 3-71 for details.
3-64. LOCAL Switch: This switch disables re¬
mote control and enables setting measurement
conditions by front panel controls (pushbutton
switches). REMOTE lamp of HP-IB status indicator
turns off when LOCAL switch is depressed.
(When Local Lock Out does not function).
3-65. HP-IB INTERFACE CAPABILITIES: The
4262A Opt 101 has the following eight bus inter¬
face functions:
SHI: Source Handshake Capability.
AH1: Acceptor Handshake Capability.
T5: Talker (the 4262A sends measurement
data to the bus).
L4: Listener (the 4262A receives remote
control signals from the bus).
SRI: Service Request Capability.
RL1: Remote/Local Capability.
DC1: Device Clear Capability.
DTI: Device Trigger Capability.
3-66. Source and Acceptor Handshake:
SHI, AH1.
Three Bus handshake lines (DAV, NRFD and
NDAC) perform Source and/or Acceptor hand¬
shake functions.
(1) DAV (DAta Valid). DIO (Data Input Out¬
put) line is available.
(2) NRFD (Not Ready For Data). Listener
preparation for receiving data from Talker
is not yet completed.
(3) NDAC (Not Data Accepted). Listener has
not yet received data from Talker.
3-67. Talker Capability: T5.
When set to Talker by MTA (My Talk Address)
signal from controller, the 4262A sends measure¬
ment data to the Bus in one of three types of out¬
put formats:
Type A: Ordinary output format. Address
switch on the rear panel set to FMT A,
S FC F -NN. NNE-NN , S F N. NNN CRLF
U) (2) (3) (4) (5X0(6) (7) ~~W~
Type B: Output format used for Model 5150A
HP-IB Digital Recorder. Address switch on
the rear panel set to FMT B.
S FC F -NN. NNE-NN CRLF S F N.NNN CRLF
(1) (2) (3) ~ (4} (8) (lj(6; (7) (8)
Type C: Output format used in resistance meas¬
urement or LCR ONLY measurement when
no D/Q data is to be outputted. Selection
of this format is automatically done in
accordance with FUNCTION switch setting.
_S FC F_ -NN, NNE-NN CRLF
