set_by_frequency

Configure the FIR filter frequency response.

Parameters

channel integer required

Target channel

allowed values:

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

sample_rate number required

Desired sample rate

allowed values:

Moku:Lab	15.6MSa/s, 7.81MSa/s, 3.91MSa/s, 1.95MSa/s, 977kSa/s, 488kSa/s, 244kSa/s, 122kSa/s
Moku:Go	3.91MSa/s, 1.95MSa/s, 977kSa/s, 488kSa/s, 244kSa/s, 122kSa/s, 61kSa/s, 30.5kSa/s
Moku:Pro	39.1MSa/s, 19.5MSa/s, 9.77MSa/s, 4.88MSa/s, 2.44MSa/s, 1.22MSa/s, 610kSa/s, 305kSa/s
Moku:Delta	39.1MSa/s, 19.5MSa/s, 9.77MSa/s, 4.88MSa/s, 2.44MSa/s, 1.22MSa/s, 610kSa/s, 305kSa/s

units: Hz

coefficient_count number

Coefficient or tap count

default: 201

shape string

Filter shape

default: Lowpass

allowed values:Lowpass, Highpass, Bandpass, Bandstop

low_corner number

Low corner frequency. The low_corner is expressed as a fraction of the sample rate. For instance, if the sample rate is 3.91 MSa/s and the low_corner value is 0.1, the resulting low corner frequency is 390.6 kHz.

default: undefined

allowed values:0.0001 to 0.49

high_corner number

High corner frequency. The high_corner is expressed as a fraction of the sample rate. For instance, if the sample rate is 3.91 MSa/s and the high_corner value is 0.1, the resulting high corner frequency is 390.6 kHz.

default: undefined

allowed values:0.0001 to 0.49

window string

Window function

default: None

allowed values:None, Bartlett, Hann, Hamming, Blackman, Nuttall, Tukey, Kaiser

window_width integer

Window width (Only when window function is Tukey)

default: 50

kaiser_order integer

Beta/Order for kaiser window (Only when window function is Kaiser)

default: 7

strict boolean

Disable all implicit conversions and coercions.

default: true
