What You Can Save to the Analyzer’s Internal Memory

The number of registers that the analyzer allows you to save depends on the size of associated error-correction sets, and memory traces. Refer to the “Preset State and Memory Allocation” chapter for further information.

You can save instrument states in the analyzer internal memory, along with the following list of analyzer settings. The default lllenames are REG<OlSl>.

nerror-corrections on channels 1 and 2

ndisplayed memory trace

w print/plot definitions w measurement setup 0 frequency range

qnumber of points 0 sweep time

0 output power

0 sweep type

0 measurement parameter

Note When the ac line power is switched off, the internal non-volatile memory is retained by a battery. The data retention time with the 3 V, 1.2 Ah battery is as follows:

Temperature at 70 OC . . . . . . . . . . . . . . . . . . . 250 days (0.68 year) characteristically Temperature at 40 OC . . . . . . . . . . . . . . . . . . 1244 days (3.4 years) characteristically Temperature at 25 OC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 years characteristically

What You Can Save to a Floppy Disk

You can save an instrument state and/or measurement results to a disk. The default filenames are PILEn, where n gets incremented by one each time a iile with a default name is added to the directory. The default illenames for data-only llles are DATAnDn (DATAn.Dn for DOS), where the first n is incremented by one each time a iile with a default name is added to the directory. The second n is the channel where the measurement was made. When you save a tie to disk, you can choose to save some or all of the following:
