Installing Optional Measurement Personalities
To see the size of your installed memory for PSA Series Spectrum Analyzers:
1. Ensure that the spectrum analyzer is in spectrum analyzer mode because this
can affect the screen size.
2. Press
System, Show System. Under Options look for 115.
3. Press
System, More, Show Hdwr.
4. Read Flash Memory size in the table.
If you have 48 MBytes of memory, and you want to install more than 3 optional
personalities, you may need to manage your memory resources. The following
section, “How to Predict Your Memory Requirements” on page 33, will help you
decide how to configure your installed options to provide optimal operation.
