AWG610 Arbitrary Waveform Generator User Manual

”output_filename” is the complete file name (file name and extension) to contain

the filtered waveform data. The argument can include a relative or absolute path

name. Enclose the file name within double quotation marks.

”filename1” is the complete (file name and extension) name of the source file for

the low pass filter operation. The file must be on the active drive. The argument

can include a relative or absolute path name. Enclose the file name within double

quotation marks.

cutoff_freq is the low pass filter cutoff frequency. You can enter the integer

value.

taps is the number of delay elements that composes the digital filter. The range

of taps is 3 to 101. You must enter the integer value as an odd number.

atten is the inhibit zone attenuation factor, in dB. The range of attenuation is

21 dB to 100 dB. You can enter the integer value.

”filtered.wfm” = lpf(”sine.wfm”, 10.454e2, 2, 30)
