3-200 AWG710&AWG710B Arbitrary Waveform Generator User Manual
Arguments
"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.
Example
"filtered.wfm" = lpf("sine.wfm", 10.454e2, 2, 30)
