INSTALLATION
AND OPERATION
The command syntax for memory operations follows. No memory location needs to be
specified for the sequence operation.
Select Memory Function
-
Enter Memory Location
To store the current front panel setting, press the [STO] key (located below the DATA
keys). The last memory
location
stored or recalled is displayed in the FREQUENCY
display field. Next, use the DATA keys to enter the two-digit memory location code. The
location code
must contain both digits (e.g.,
01,
02,
...50). The two-digit code appears in
the FREQUENCY display field
as
it
is
entered.
To recall a front panel setting, press the [RCL] key (located below the DATA keys). The
last memory location stored or recalled is displayed in the FREQUENCY display field.
Next, use the DATA keys to enter the memory location code
of
the desired front panel
setting. Remember, the location code must contain both digits
of
the memory location
code.
Memory location 98 contains the Instrument Preset State that
can
be recalled
at any time.
The [SEQ] key allows the front panel settings stored
in
memory to be sequentially
recalled.
This
process is activated by pressing the
[SEQ]
key
at any
time. When the
[SEQ]
key is pressed, the memory location code of the currently
recalled
setting
appears
in
the
FREQUENCY display field, and the location is recalled. When the last memory location
is reached
(50),
the [SEQ] key starts over at 01. The [SEQ] key repeats while pressed.

Special Function
Special Function Entries allow the operator to enable several special operating functions
in the
Generator.
For example, special functions allow the operator to change the
repeat
rate of the STEP and EDIT keys, start the self tests, display the results of the power-up
self tests, display
the IEEE-488 address, enable relative and
fixed-range
features, and
disable or enable special attenuation features. A complete list of the special functions
available is presented in Table
2-4.
The command syntax for special function
entries
is as follows:
Select Special Function
—
Enter Special
Function
Code
The special function is selected by pressing the [SPCL] key. The special function code is
entered using the DATA keys.

OPERATING REFERENCE MATERIAL
This reference section describes local and remote operation for each Generator function.
The functions are arranged in alphabetical order. For each function, the syntax of the
command, allowable data ranges, and other information
is presented.
2-22.
Amplitude
and Frequency Entry
The following information describes how to control the carrier frequency and amplitude
by the FUNCTION-DATA-UNIT entry sequence. This method applies to both normal
and
relative operations. The
frequency
display is a fixed-point display in
MHz. The
amplitude display is fixed point while displaying
dBm but
is
floating point when
displaying voltage units.
The RF OUTPUT [ON/OFF] must be enabled for the Generator to produce an output
(see the reference material on RF OUTPUT ON/ OFF Entry).
