Files: Storing Files

• Spectrum scans—including regular, zero-span, and CSO/CTB

measurements. Regular measurements can also include peak-hold

values.

• Tilt measurements

• PathTrak measurements—including Local and Remote traces.

Channel plans and Spectrum mode settings can be stored as files, too.

All the files stored in your unit exist in a common pool of non-volatile

memory. When a file is stored, the instrument uses only the memory actually

required for the data. Different file types, or different settings within the same

type, can use different amounts of memory. To see a display of how much

memory is still available, press the Function key, followed by the Chan key.

The bar graph next to the File soft icon shows what percentage of memory is

currently used.

You can use the Navigator menu to gain access the VIEW screen.

To work with the VIEW menu, press the green Function key, then the 2 def

key. Alternatively, you can enter the VIEW menu through the Navigator. You

can store, view, and print sweep, spectrum, and PathTrak files.

1. There are three basic displays in View mode:

• File: store measurement files

• View: view measurement files

• The display for the Measured File being viewed

2. If you press the Function and 2 def keys during a measurement, the

measurement can be stored as a file. The instrument enters File mode

to store the current measurement. If you press these keys while you

are in a mode that does not produce files (such as Level mode), the

instrument enters View mode to allow you to review existing files.

The SDA-5000 enables you to store measurements made with the Scan,

Spect (Spectrum Analyzer Mode), Tilt, Sweep, PathTrak, and the shifted

QAM measurement mode keys.
