Saving And Recalling Data From The Memory Card; Comparison Of Analyzer Memory And Memory Card Operations - HP 8590 E-Series User Manual

Saving and Recalling Data from the Memory Card

Note
Option 003 is required when using an HP 8590L or HP 8592L.
The memory card provides additional memory for saving instrument states, traces
images, limit-line tables, amplitude correction factors, and programs. Each HP 857'00A
battery-backed RAM card provides 32 kilobytes of memory. Several different memory cards are
available with up to 512 kilobytes of memory. See "Accessories" in Chapter 10. Instrument
states, traces, display images, limit-line tables, amplitude-correction factors, and programs are
easily retrievable without the need for an external controller to transfer data.
The process of saving and recalling data from the memory card is similar to saving and
recalling data from the spectrum analyzer memory. Due to the expanded capabilities of the
memory card, there are some important differences. For example, data is stored in spectrum
analyzer memory as an item; on the memory card data is stored as a logical interchange file
(LIF). Memory card data can be stored and recalled using a prefix. A prefix is an optional
user-defined label for states, traces, and programs. The prefix becomes part of the file name. If
you do not specify a prefix, the file name will be created without it. tible 5-2 compares the
save and recall operations of spectrum analyzer memory and the memory card.
Refer to Table 5-3 at the end of this section for a summary of saving and recalling data to and
from spectrum analyzer memory.
