User Manual 301/302

FREQuency:RASTer:SOURce EXTernal | INTernal

Purpose

This command selects the source of the sample clock generator. This command affects both the standard

and the arbitrary waveforms.

• <EXTernal> selects an external source

• <INTernal> selects the internal source

FREQuency:RASTer:SOURce?

Response

The 302 will return EXT if an external source is selected, or INT if the internal source is selected.

FUNCTion:MODE FIXed | USER | SEQuence

Purpose

This command defines the type of waveform that will be available at the output connector.

• <FIXed> selects standard waveforms

• <USER> selects arbitrary waveforms

• <SEQuence> selects sequenced waveforms

FUNCTion:MODE?

Response

The 302 will return FIX, USER, or SEQ depending on the present 302 setting.

GAUSsian | DC}

Purpose

This command defines the shape of waveform that will be available at the output connector. This command

has no affect if present 302 setting is USER or SEQ.

• <SINusoid> selects sine waveform

• <TRIangle> selects triangular waveform

• <SQUare> selects square waveform

• <PULSe> selects pulse waveform

• <RAMP> selects ramp waveform

• <SINC> selects sinc waveform

• <EXPonential> selects exponential waveform

• <GAUSsian selects gaussian waveform

• <DC> selects dc waveform

FUNCtion:SHAPe?

Response

The 302 will return SIN, TRI, SQU, PULS, RAMP, SINC, EXP, GAUS, or DC depending on the present 302

setting.
