REMOTE-CONTROL PROGRAMMING
The
Option -488 IEEE-488
Interface allows the
Generator
to
be remotely controlled with
any IEEE-488
bus
controller.
The
instrument can
also
be used
on
the
1EEE"488
bus
without a
controller
in
a
listen-only or talk-only
mode
by
selecting the appropriate
Generator
rear
panel
IEEE-488
switch
settings.
All
instrument
controls
can
be remotely controlled except
the
POWER ON
/
OFF
and
the
rear panel
REF
INT/EXT
switches.
The
Option -488 IEEE-488
Interface
provides
additional
commands
not available with
local control,
such
as data
transfer
and
individual control of
internal
I/O
control
bits.
The
Option
-488
IEEE'488
Interface allows two Generators
to track amplitude,
frequency, or modulation
in
a master/ slave configuration
when
using the front panel
step-up
and
step-down
entries
on one
of
the instruments.
For
instance, frequency
tracking
is
convenient
for
tests
involving mixers, and
amplitude tracking
is
useful for
two-
tone intermodulation
testing.
1-10- Frequency
The
specified
frequency range
is
0.01 to 1050
MHz.
The
frequency
is
synthesized
from
a
10-MHz
reference
and
provides
an
output resolution of 10
Hz
over the
entire frequency
range.
The
relative
frequency
mode
allows the frequency
to
be
programmed
in relation to
a center frequency or an
offset
frequency. This
is
convenient
for testing
filters
and
mixers.
The
output frequency
stability
and
accuracy depends on
the
reference,
whether
that
reference
is
internal
or
external.
1-11,
Reference
The
internal frequency
reference
is
a 10-MHz
ambient
crystal
oscillator. If
Option -130
High
Stability
Reference or
the
option -132
Medium
Stability
Reference
is
installed,
that
oscillator
is
locked
to the internal crystal
oscillator.
With
the rear panel
REF
INT/
EXT
switch
set to
INT,
the Generator output frequency
is
synthesized
from
the
internal
10"MHz
crystal oscillator reference,
and
the internal
oscillator (timebase) signal
is
available
at the 10
MHz OUT
connector.
The
Generator can be
operated
from an
external
10-MHz
timebase
by
setting
the rear
panel
REF
INT/EXT
switch
to
EXT
and
applying
a
timebase
signal
to the
REF
IN
connector.
With
the
REF
INT/EXT
switch
set to
EXT,
the
Generator can be operated
from an
external
1-, 2-, 2.5-, 5-,
or
10-MHz,
0.3V
to
4V
peak-to-peak
sine or
square-wave
reference applied to the
REF
IN
connector. In
either
position of the
INT/EXT
switch,
the selected reference
is
available as a
lO-MHz
signal at
the rear panel 10
MHz OUT
connector.
1-12.
Amplitude
The
Generator
has a specified signal
level
range
from +13
to
-127
dBm
with
programming
limits
of +19 and
-147.4
dBm.
This corresponds
to specified
terminated voltages of
IV
to
0.1
/xV
and
limits of
2V
to 0.01
/iV, respectively.
The
maximum
usable
signal level
is
approximately +15
dBm. The
level
entry can be
in
dBm
or
volts,
or
it
can be
converted
from one
to the other.
In
addition, the relative amplitude
mode
allows
you
to
account
for
cascaded gain
or
loss,
or to display the
level (in
dB)
relative to
1
mV
or
1
mV.
1-13.
Modulation
Both
internal
and
external amplitude modulation and
frequency modulation
capability
is
available.
The
internal modulation
oscillator
is
selectable
between 400
Hz
and
1000 Hz.
