9 Analog Commands

[:SOURce]:FM[1]|2:INTernal[1]|2:FUNCtion:RAMP?

Selects a positive or negative ramp as the internal modulating waveform. Refer to

“:FM[1]|2:INTernal[1]|2:FUNCtion:SHAPe" on page 288 for the waveform selection.

Example

:FM2:INT2:FUNC:RAMP POS

The example selects a positive sloped ramp as the internal modulating waveform.

*RST POS

:FM[1]|2:INTernal[1]|2:FUNCtion:SHAPe

Supported Option UNT

RAMP|NOISe|DUALsine|SWEPtsine

[:SOURce]:FM[1]|2:INTernal[1]|2:FUNCtion:SHAPe?

Selects the FM waveform type. The INTernal2 source selection does not support the

dual–sine or Sweep–Sine waveform types.

Example

:FM2:INT1:FUNC:SHAP SQU

The example selects a square wave as the internal modulating waveform.

*RST SINE

:FM[1]|2:SOURce

Supported Option UNT

[:SOURce]:FM[1]|2:SOURce INT[1]|INT2|EXT1|EXT2

[:SOURce]:FM[1]|2:SOURce?

Selects the FM source.

INT Selects internal source 1 or 2 to provide an ac-coupled signal.

EXT Selects the EXT 1 INPUT or the EXT 2 INPUT connector to provide an externally

applied signal that can be ac- or dc-coupled. The externally applied, ac-coupled input signal

is tested for a voltage level and an annunciator, on the N8211A/N8212A’s front-panel

display, will indicate a high or low condition if that voltage is > ±3% of 1 V
