Analog Commands 9

Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz 287

Sets the internal FM rate using the <val><units> variable, or changes the FM rate by a

user-defined up/down step value. Refer to the

“:FM:INTernal:FREQuency:STEP[:INCRement]" on page 283 for setting the value associated

with the UP and DOWN choices.

The command changes:

• the FM rate of the first tone of a dual–sine waveform

• the starting FM rate for a swept–sine waveform

• the FM rate for all other waveforms

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

selection.

Example

:FM2:INT:FREQ 40KHZ

The example sets the modulation rate for FM path 2 to 40 kHz.

*RST +4.00000000E+002

Range Dual-Sine & Sine: 0.5 Hz - 1 MHz Swept-Sine 1 Hz to 1 MHz All other

waveforms: 0.5 Hz - 100 kHz

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

Supported Option UNT

[:SOURce]:FM[1]|2:INTernal[1]|2:FUNCtion:NOISe GAUSsian|UNIForm

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

Selects a gaussian or uniform noise type as the modulation. Refer to

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

Example

:FM2:INT2:FUNC:NOIS UNIF

The example selects a uniform noise waveform as the modulation for FM path 2 and FM

source 2.
