Using the Instrument State Registers
The instrument state register is a section of memory divided into 10 sequences (numbered 0 through 9)
with each sequence consisting of 100 registers (numbered 00 through 99). Instrument state sequences and
registers are used to store and recall instrument settings and provide a quick way to reconfigure the signal
generator when switching between different instrument and signal configurations. The signal generator
has 20 MB available for data and instrument state storage. The signal generator Instrument state files can
vary in length depending on the signal generator’s configuration.
File data, such as modulation formats and table entries, are not stored with the save function. Only setups
such as frequency, attenuation, power and other user- defined settings that do not survive a power cycle or
instrument reset can be saved to a sequence and register. Any data file associated with the instrument
state will only be referenced by its file name. Once an instrument state has been saved, recalling that state
will set up the generator with the saved settings and load the associated file data.
For more information on storing file data such as modulation formats and table entries refer to
“Storing Files to the Memory Catalog” on page 33
. Refer to the
E8663B Analog Signal Generator
Programming Guide
and the
E8663B Analog Signal Generator Key Reference
for more information
on the save and recall function.
NOTE
A reference to a file is saved along with the instrument state. However, no data is saved with the
save function. You must store file data, using store commands, in a different memory location.
Saving an Instrument State
1.
Preset the signal generator, then turn on amplitude modulation (the
AM
annunciator will turn on):
a.
Press
Frequency
>
800
>
MHz
.
b.
Press

.
2.
Press
Save
>
Select Seq
.
The sequence number becomes the active function. The signal generator displays the last sequence
used. Using the arrow keys, set the sequence to 1.
3.
Press
Select Reg
.
The register number in sequence 1 becomes the active function. The signal generator displays either
the last register used accompanied by the text:
(in use)
, or (if no registers are in use) register 00
accompanied by the text:
(available)
. Use the arrow keys to select register 01.
4.
Press
Save Seq[1] Reg[01]
.
This saves this instrument state in sequence 1, register 01 of the instrument state register.
