generate_waveform

Configures the output waveform for each channel

The maximum number of points depends on the sample rate:

For Moku:Pro

• 16,384 at 1.25 GS/s
• 32,768 at 625 MS/s
• 65,536 at 312.5 MS/s

For Moku:Lab

• 8,192 at 1Gs
• 16,384 at 500Ms
• 32,768 at 250Ms
• 65,536 at 125Ms

For Moku:Go

• 8,192 at 125 MS/s
• 16,384 at 62.5 MS/s
• 32,768 at 31.25 MS/s
• 65,536 at 15.625 MS/s

Values will be normalized to the range [-1.0, +1.0] and then scaled to the desired amplitude and offset.

Parameters

channel integer required

Target output channel to generate waveform on

allowed values:

Moku:Lab	1, 2
Moku:Go	1, 2
Moku:Pro	1, 2, 3, 4

sample_rate string required

Defines the output sample rate of the AWG. If you don’t specify a mode, the fastest output rate for the given data length will be automatically chosen. This is correct in almost all circumstances.

allowed values:

Moku:Lab	Auto, 1Gs, 500Ms, 250Ms, 125Ms
Moku:Go	Auto, 125Ms, 62.5Ms, 31.25Ms, 15.625Ms
Moku:Pro	Auto, 1.25Gs, 625Ms, 312.5Ms

units: MS/s

lut_data array

Lookup table voltage values. The entries of the LUT are normalized to range [-1.0, 1.0]; if the LUT entries are identically zero then it remains unchanged.

default: undefined

allowed values:array of -inf, inf

frequency number required

Frequency of the waveform

allowed values:

Moku:Lab	1e-3 to 10e6
Moku:Go	1e-3 to 10e6
Moku:Pro	1e-3 to 250e6

units: Hz

amplitude number required

Waveform peak-to-peak amplitude (For Moku:Pro, the output voltage is limited to -1V to 1V with a sample rate of 1.25GSa/s)

allowed values:4e-3 to 10

units: V

phase number

Waveform phase offset

default: 0

allowed values:0 to 360

units: Deg

offset number

DC offset applied to the waveform

default: 0

allowed values:-5 to 5

units: V

interpolation boolean

Enable linear interpolation of LUT entries.

default: false

load string deprecated

Waveform load

default: 1MOhm

allowed values:

Moku:Lab	50Ohm, 1MOhm
Moku:Go	1MOhm
Moku:Pro	50Ohm, 1MOhm

strict boolean

Disable all implicit conversions and coercions.

default: true
