4. Press Catalog Type > All .
The “Catalog of All Files” is displayed. For a complete list of file types, refer to Table 2- 1 on
page 61 .
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 with either Option 005 (internal hard drive – 4 GB), or Options 008, and 009
(flash drive – 8 GB) installed, utilizes the memory for storing instrument state files and other user
data. If these options are not installed, the signal generator has 20 MB available for data and
instrument state storage. Instrument state files can vary in length depending on the signal
generator’s configuration.
File data, such as modulation formats, arb setups, 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,
such as an arb format 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 setup the generator with the
saved settings and load the associated file data.
For more information on storing file data such as modulation formats, arb setups, and table entries
refer to
“Storing Files to the Memory Catalog” on page 62 . Refer to the Agilent Signal Generators
Programming Guide and the Agilent PSG Signal Generators 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 Amplitude > 0 > dBm .
c. Press AM > AM Off On .
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] .
