OPERATOR INFORMATION CARD
The Operator Information Card has an adhesive backing
so it may be affixed to the top of
the Generator in bench applications or to the
operator console in remote applications. A
copy of
the card
is
located at
the
end of Section 8 of this manual
as
a
convenient
reference
or for duplication.

GENERATOR DESCRIPTION
Fundamental features of the Generator are
as follows:
0.01-MHz to 1050-MHz
frequency range in 10-Hz steps
+
I3-dB to
-127-dBm level
range in 0.1-dB steps
AM and FM, internal or external
Internal 400-Hz and lOOO-Hz modulation
oscillator
Relative frequency and amplitude
Volts/
dBm conversion
Store/recall memory
Master/slave
for
frequency,
amplitude, and modulation step (IF.EE488
Interface
controlled.)
Fluorescent display
5

/4-inches high,
rack mountable
1-6. Controller Functions
The
Controller
microprocessor
controls all operator interface functions, performs
background operations such as status checks, and updates
(strobes) the front panel
displays. Whether you are using local control with the front
panel, or remote control with
the IEEE-488 Interface option, the microprocessor provides .self test
and diagnostic
capability.
Economical
instrument performance is achieved
by
using software
compensation EPROMs and accuracy-enhancement circuitry.

LOCAL
CONTROL
The value of the basic output parameters
of the Generator, i.c., amplitude, frequency, or
modulation can be controlled in three ways:
Direct
numeric entry
Incrementing or decrementing the bright digit
Step-up or step-down entry where the step size can
be
operator programmed
Other controls provide selection of the POWER ON/OFF, RF
OUTPUT
ON/OFF,
MODULATION ON/OFF, internal/external
frequency
reference, and STATUS.
1-8.
DISPLAY FIELD
The programmed values of modulation, frequency, and amplitude are displayed in the
three display fields.
