Basic Digital Operation (Option 653/655/656/657)
Saving a Waveform’s Settings & Parameters
The Current Inst. Settings column shows the current signal generator settings. In this
example, these are the settings that you will save to the file header.
NOTE If a setting is unspecified in the file header, the signal generator uses its current value for
that setting when you select and play the waveform.

3. Save the information in the Current Inst. Settings column to the file header:
Press Save Setup To Header.
Both the Saved Header Settings column and the Current Inst. Settings column now display
the same values; the Saved Header Settings column lists the settings saved in the file header.
4. Edit and Update Settings
a. Return to the ARB Setup menu:
Press Return > More > ARB Setup.
From this menu you can access some of the signal generator settings that are saved to the file
header. Figure 8- 1 on page 147 shows the ARB Setup softkeys used in the following steps.
b. Set the ARB sample clock to 5 MHz:
Press ARB Sample Clock > 5 > MHz.
c. Set waveform runtime scaling to 60%:
Press Waveform Runtime Scaling > 60 > %.

The description can be up to
32–characters.

To calculate the RMS waveform voltage:
Press Calculate
Then refer to Header Field information.
Note: For greater accuracy, if the waveform has long rise/fall times, a DC
offset, or noise* already added to the waveform (for a bursted signal), it
is recommended that the Edit RMS and Edit AWGN RMS Override
softkeys are used for the best measurement accuracy.
*Option 403 Real–time AWGN does not affect the Header Field RMS
value. But, noise added to the waveform prior to downloading and
playing in the signal generator does affect the Header Field RMS value.
Opens a menu for manually
defining the carrier RMS value
to use for calculating the
AWGN: Carrier RMS value in
the Header Field.
