:WGEN Commands 33
Agilent InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide 1023
:WGEN:MODulation:TYPE
(see page 1138)
Command Syntax
:WGEN:MODulation:TYPE <type>
<type> ::= {AM | FM | FSK}
The :WGEN:MODulation:TYPE command selects the modulation type:
• AM (amplitude modulation) — the amplitude of the original carrier
signal is modified according to the amplitude of the modulating signal.
Use the :WGEN:MODulation:AM:FREQuency command to set the
modulating signal frequency.
Use the :WGEN:MODulation:AM:DEPTh command to specify the amount
of amplitude modulation.
• FM (frequency modulation) — the frequency of the original carrier
signal is modified according to the amplitude of the modulating signal.
Use the :WGEN:MODulation:FM:FREQuency command to set the
modulating signal frequency.
Use the :WGEN:MODulation:FM:DEViation command to specify the
frequency deviation from the original carrier signal frequency.
• FSK (frequency- shift keying modulation) — the output frequency "shifts"
between the original carrier frequency and a "hop frequency" at the
specified FSK rate.
The FSK rate specifies a digital square wave modulating signal.
Use the :WGEN:MODulation:FSKey:FREQuency command to specify the
"hop frequency".
Use the :WGEN:MODulation:FSKey:RATE command to specify the rate at
which the output frequency "shifts".
Query Syntax
:WGEN:MODulation:TYPE?
The :WGEN:MODulation:TYPE? query returns the selected modulation type.
Return Format
