T o Use Previously Stored Level Correct Data
When the level correct routine is run, the synthesizer creates a table of
correction values for each frequency point in the table . Up to four level
correction tables can be stored in the synthesizer memory . If the current
signal path at the synthesizer output (the external signal path) is identical to
the external signal path on which a level correct routine had been previously
run, the level correction table can be recalled from memory and be used at a
later time .
1. V erify that the current external signal path is correct for the level
correct table you want to recall from memory and use .
The current external signal path must be identical to the external signal
path that was calibrated and stored in the level correct table that you wish
to recall. If the current external signal path is dierent, the data can cause
inaccurate output power levels at the output of the external signal path.
2. Press the 4 SHIFT 5 key and then the 4 EXT METER 5 (RCL CR) key .
The display will show RECALL FRM TABLE XXX where XXX is the last level
correction register number recalled.
3. Enter the level correction register number of the register that contains
the level correct data you want to use .
F or example , use the following procedure to choose level correction
register number 2.
a. Type 4 2 5 on the synthesizer numeric keypad.
b. T erminate the level correction register number entry by pressing the
4 Hz 5 (ENTER) key .
4. Press the 4 SHIFT 5 key and then the 4 POWER LEVEL 5 (L VL CR ON/OFF) key
to enable the synthesizer to use of level correct data when determining
the output power level.
When the use the level correct data has been enabled, the L VL CR
annunciator will be lit.
