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.

Software Compensation Procedures
The software compensation procedures allow the operator
to update the instrument-specific
compensation data after making related repairs.
These procedures are easy to use
and may be
performed via
the front panel (local) or under computer control
(remote) through the
IEEE-488 Interface. The local procedures enable secondary
functions for many of the
keys.
Each remote procedure enables
a
special
set of compensation commands
and
disallows
much
of
the standard
IEEE-488 command set. See Section 4E, Software
Compensation Procedures,
for details.

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-on
self tests, display
the
IEEE-488
addresU 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:
Select Special Function
—
Enter Special Function
Code
1. Select the special function by pressing the [SPCL] key.
2. The
special function code is entered using the DATA keys.

LOCAL AND
REMOTE CONTROL OPERATIONS
The following paragraphs describe local and remote operations that have similar entry
methods for
each Generator function. The functions
are
arranged in alphabetical
order.
The
syntax of the command and allowable data ranges are for each function. Other information
is
also presented.
2-23.
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 Boating
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.)
