Basic Operation
Using the Instrument State Registers
Saving an Instrument State
1. Preset the signal generator, then turn on amplitude modulation (the
AM
annunciator will turn on):
a. Press
Frequency
>
800
>
MHz
.
b. Press
Amplitude
>
0
>
dBm
.
c. Press
AM
>
AM Off On
.
2. (Optional) If you want to associate these settings with a waveform file, load the waveform file into
WFM1 and select it. Refer to “Storing and Loading Waveform Segments” on page 112 for information
on loading waveform files into WFM1.
3. Press
Save
>
Select Seq
>
1
>
Enter
.
The sequence number becomes the active function. The signal generator displays the last sequence used.
Using the arrow keys, set the sequence to 1.
4. Press
Select Reg
>
1
>
Enter
.
The register number in sequence 1 becomes the active function. The signal generator displays either the
last register used accompanied by the text:
(in use)
, or (if no registers are in use) register 00
accompanied by the text:
(available)
. Use the arrow keys to select register 01.
5. Press
Save Seq[1] Reg[01]
.
This saves the instrument state, configured in step 1, to sequence 1, register 01 of the instrument state
register. If a waveform is selected or being played, then the name of the waveform file will also be saved
in sequence 1, register 01 of the instrument state register.
6. Press
Add Comment to Seq[1] Reg[01]
.
This enables you to add a descriptive comment to sequence 1 register 01. The comment appears in the
Saved States list when the
Recall
hardkey is pressed. If you have a waveform associated with the
instrument state, enter the name of the waveform in the comment field. You can then easily identify the
name of the waveform and associated instrument state when the
Recall
hardkey is pressed.
7. Using the letter softkeys, front-panel knob, or numeric keypad, enter a comment and press
Enter
.
8. Press
Edit Comment In Seq[1] Reg[01]
.
If you wish, you can now change the descriptive comment for sequence 1 register 01.
Changes to a previously saved instrument state, for example an instrument state saved in Seq n, Reg nn, can
be re-saved by highlighting that register and pressing
Re-SAVE Seq[n] Reg[nn]
. The re-save function
overwrites previously saved instrument state settings, with the new settings configuration.
