AWG610 Arbitrary Waveform Generator User Manual

Brf( )

The brf() statement creates a new waveform file by passing the specified

waveform file through a band-rejection filter.

Waveform

”output_filename” = brf(”filename1”, cutoff_freq_lo,

cutoff_freq_hi, taps, atten)

”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 band-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_lo is the band-reject filter low-frequency cutoff value. You can enter

the value as a real or scientific notation number or as an expression that resolves

to a valid number.

cutoff_freq_hi is the band-reject filter high-frequency cutoff value. You can enter

the value as a real or scientific notation number or as an expression that resolves

to a valid number.

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” = brf(”sine.wfm”, 3.0e6, 5.0e6, 101, 45)
