Frequency1

Generator Range

• The [SOURce:]FREQuency[1]:RANGe command allows for higher

sample frequency operations of the USER function. This command

is only used with frequency1 generator. If set to

0 (MINimum), the

normal setting, the maximum sample frequency is the

Reference Oscillator frequency / 4

• If set to MAXimum, the maximum sample frequency is the

Reference Oscillator frequency / 2

The

MAXimum setting worsens the frequency resolution by a factor

of two and introduces some sample rate jitter.

Returning the

Waveform Segment

Names

Use [SOURce:]LIST[1][:SEGMent]:CATalog? to return the names of the

different waveform segments stored in memory. The command returns

comma-separated strings that contain the names of the segment lists.

Determining the

Waveform Segment

Size

Use [SOURce:]LIST[1][:SEGMent]:VOLTage:POINts? to determine the size,

in number of waveform segments or points, of the currently selected

waveform segment.

Returning the

Segment Sequence

List Names

Use [SOURce:]LIST[1]:SSEQuence:CATalog? to return the names of the

different segment sequence lists stored in memory. The command returns

comma-separated strings that contain the names of the segment sequence lists.

Returning the

Repetition Count

List Length

Use [SOURce:]LIST[1]:SSEQuence:DWELl:COUNt:POINts? to determine

the length of the currently selected segment sequence’s repetition count list.
