SECTION III
Model 4277A
3-113.
OPTION 002 COMPARATOR/HANDLER
INTERFACE
3-114.
Option 002 equips the standard 4277A
with
a
comparator
function
and
a
handler
(component sorter)
interface capability.
The
comparator
provides
go/no-go
testing
and
ten-bin sorting.
The handler interface is for
control of an automatic component handler.
3-115.
Up to nine sets of high/low limits for L,
C,
or
i Z1
measurement,
and
one
set
of
high/low limits for D, Q, ESR, or G measurement
can be keyed in from the 16064A keyboard or
entered via the HP-IB.
When measurement is
made, the comparator compares the measured
values displayed on DISPLAY A and DISPLAY B
with the stored high/low limits. If the measured
values fit any set of limits, the bin number for
that set is displayed on the FREQUENCY/DC
BIAS display. If the measured values do not fit
any of the limits, zero (0), the number for the
out-of-Iimits
bin,
is
displayed.
Go/no-go
decisions
are
indicated
by
two
sets
of
LOW/IN/HIGH
LED
lamps
on
the
16064A
keyboard.
Comparator/Handler
Interface
operation is described in Figures 3-34.
3-116. The
16064A
has
a
36-pin
female
Amphenol connector
for interfacing with an
automatic
component
handler.
The
16064A
sends
comparison
results—LOW/IN/HIGH
decisions and bin number—to the handler, and
receives control signals via a user-fabricated
interface cable constructed using the furnished
36-pin
male
Amphenol
connector
(P/N
1251-0084). Pin assignments are given in Figure
3-33.
For complete information, refer to the
i6064A Operation Note.
