Saving and Recalling Data from Analyzer Memory

This section explains how to save and recall state, trace, limit line, and amplitude correction
factor data to and from spectrum analyzer memory. You can use STATE + INTRNL to store
up to eight states in analyzer memory, and Trace + Intrnl to store many traces, limit-line
tables, and amplitude-correction factors.
Saving state data saves the spectrum analyzer settings, but not the trace data. Saving trace
data saves the trace data and the state data. Limit-line data and amplitude correction factors
are stored in trace registers, but state and trace data are not recalled with the limit-line data
or the amplitude correction factors. States, traces, limit-line tables, and amplitude correction
factors are saved in spectrum analyzer memory even if the instrument is turned off or [PRESET]
is pressed.
Refer to the Catalog Internal softkey description in Chapter 7 for more information about
cataloging spectrum analyzer memory.
Refer to Table 5-1 at the end of this section for a summary of saving and recalling data to and
from spectrum analyzer memory.
To Save a State
1. Set up the spectrum analyzer settings to be saved.
INTERNAL selects the spectrum analyzer memory as the mass storage device.
3. Press STATE -+ INTRNL . SAVE: REG is displayed on the spectrum analyzer display.
4. Enter a number from one to eight using the numeric keypad and the state is saved
automatically.

To Recall a State

3. Enter the register number under which the state was saved and the state is recalled
automatically.
State data can also be recalled by using the catalog:
of the state register to be retrieved. The state registers have a "ST" preceding the register
number.
3. Press LOAD FILE.
Note
Register 9 is a special register which can aid in recovering from inadvertent loss
of line power (power failure). Press (RECALL], INTERNAL -+ STATE, then 9 to
place the spectrum analyzer in the state that existed just prior to the loss of
power or set POWER ON LAST to do this automatically.
