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 9-1 on page 188 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 > % .
d. Return to the Header Utilities menu:
Press Return > More > Header Utilities .
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.

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.
