Pulse modulation

You can use these commands to switch the pulse modulation on and off when it is part of the modulation mode. When ON is selected the carrier is modulated by the logic level applied to the PULSE INPUT socket.

Pulse ON

Logic level between 3.5 and 5 V

Pulse OFF

Logic level between 0 and 1.0 V

Note: the :PULSE:ON and :PULSE:OFF commands are invalid when used with Option 11 (fast pulse). :PULSE? always returns :PULSE:ON when used with Option 11.

PULSE

[not used alone]

:ON

Turn Pulse modulation ON

:OFF

Turn Pulse modulation OFF

Data type :

None

 

Allowed suffices :

None

 

Default suffix :

None

 

Examples:

PULSE:ON

 

PULSE:OFF

PULSE?

Prepares message containing information on Pulse Modulation setting in

 

the following format:

 

:PULSE:<status>

 

where:

<status> is a program mnemonic indicating whether the

 

 

pulse modulation is ON or OFF

Examples:

:PULSE:ON

 

:PULSE:OFF

Examples:

:PULSE:ON

 

:PULSE:OFF

To enable pulse modulation:

Select any modulation mode together with pulse: for example, :MODE AM,PULSE.

Turn pulse modulation on :PULSE:ON(this command is valid for instruments that do not contain Option 11).

Turn the AM off by sending :AM:OFF. This disables the AM but leaves pulse modulation enabled.

To disable pulse modulation:

Turn pulse modulation off :PULSE:OFF(this command is valid for instruments that do not contain Option 11) or set a new modulation mode without pulse (for example, :MODE:AM). This command is valid for all instruments.
