Customizing a Multicarrier Setup
In this procedure, you learn how to customize a predefined multicarrier digital modulation setup by creating
a custom 3-carrier EDGE digital modulation state.
1. Press
Preset
.
2. Press
Mode
>
Custom
>
Arb Waveform Generator
>
Multicarrier Off On
.
3. Press
Multicarrier Define

>
Done
.
4. Highlight the
Freq Offset
value (
500.000 kHz
) for the carrier in row 2, and
press

>
kHz
.
5. Highlight the
Power
value (
0.00 dB
) for the carrier in row 2, and press
Edit Item
>
−
10
>
dB
.
You have a custom 2-carrier EDGE waveform with a carrier at a frequency offset of
−
625 kHz and a
power level of
−
10.00 dBm.
6. Press
Return
>
Digital Modulation Off On
.
This generates a waveform with the custom multicarrier EDGE state. The display changes to
Dig Mod
Setup: Multicarrier (Modified)
. During waveform generation, the
DIGMOD
and
I/Q
annunciators appear and the new custom multicarrier EDGE state is stored in volatile memory.
7. Set the RF output frequency to 890.01 MHz.
8. Set the output amplitude to
−
10 dBm.
9. Press
RF On/Off
.
The custom multicarrier EDGE waveform is available at the RF OUTPUT connector; it does not include
bursting or channel coding.
10. Press
Mode
>
Custom
>
Arb Waveform Generator
, where
Digital Modulation Off On
is the first softkey.
11. Press
Multicarrier Off On
>

Store To File
.
If there is already a file name from the
Catalog of MDMOD Files
occupying the active entry area,
press
Edit Keys
>
Clear Text
.
12. Enter a file name (for example,
EDGEM1
) using the alpha keys and the numeric keypad, and press
Enter
.
The user-defined multicarrier digital modulation state is now stored in non-volatile memory.
NOTE
The RF output amplitude, frequency, and operating state settings (such as RF On/Off) are
not stored as part of a user-defined digital modulation state file. For more information,
