Agilent Technologies 4263B LCR User Manual

In
the gure
,the
transformer
primary
is
connected
to
H
CUR
and
L
CUR
connectors
,and
the
secondary
is connected
to
the
H
POT
and
L
POT
connectors
.L
CUR
and
L
POT
are
connected as
a
common.
When
measuring the
turns
ratio
,
for
example
,
the
4263B
measures
the
primary
voltage and
secondary
voltage while
applying
an
ac
voltage
to
the
primary
.
The
4263B
calculates
the turns
ratio
from the
ratio
of
these
two
voltages
.
F
or
primary
voltage
measurement,
SW1 switches
to
H
CUR
,
and
for
secondary
voltage
measurement,
SW1
switches
to
H
POT
.
Other
parameters
are
obtained
in
a
similar
manner

The digital section
consists of the A2 CPU Board Assembly and other peripheral assemblies
such as the keyboard and LCD
. The section communicates with the A1
Main Board Assembly in
order to control the latches
, switches
, and other components on the
A1 assembly and receive
the measurement data. The GPIB interface on the A2 Assembly allows the 4263B communicate
with a controller
. A handler interface on the A1 Assembly allows the 4263B communicate
with
an external handler.
The A2 CPU Board Assembly includes a processor, ROM, EEPROM, jumpers, switches, and
LEDs.
ROM (A2U11) stores the rmware which controls all the 4263B's operation and functions. The
ROM is mounted in a socket for easy replacement.
