Basic Operation

Using Data Storage Functions

Viewing Stored Files in the Memory Catalog

1.Press Utility > Memory Catalog > Catalog Type.

All files in the memory catalog are listed in alphabetical order, regardless of which catalog type you select. File information appears on the display and includes the file name, file type, file size, and the date and time the file was modified.

2.Press List.

The “Catalog of List Files” is displayed.

3.Press Catalog Type > State.

The “Catalog of State Files” is displayed.

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 56.

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 Option 005 (internal hard drive) has approximately 4 GB available for storing instrument state files and other user data. Without Option 005, 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 56. Refer to the E8257D/67D PSG Signal Generators Programming Guide and the E7257D/67D 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.
