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.

Press (SAVE). If CARD is underlined, press INTERNAL CARD to select INTERNAL. Selecting

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

Press

@?XQ.

If CARD is underlined, press INTERNAL CARD to select INTERNAL.

Press INTERNAL

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:

Press

[RECALL].

If CARD is underlined, press INTERNAL CARD to select INTERNAL.

Press Catalog Internal and CATALOG REGISTER. Use the knob to highlight the number

of the state register to be retrieved. The state registers have a “ST” preceding the register

number.

3. Press LOAD FILE.

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.
