●
Limit is the cut-off frequency
●
Shape is gaussian or rectangle for the lowpass filter, and gaussian for the high-
pass.
► For example, to set a rectangle lowpass filter on channel 1 with 10 MHz cut-off fre-
quency, enter:
FIR(lowpass,Ch1,1e+07,rectangle)
► For example, to set a Gaussian highpass filter on channel 2 with 3 GHz cut-off fre-
quency, enter:
FIR(highpass,Ch2,3e+09,gaussian)
Bandpass and bandstop FIR filter
The syntax for the bandpass filter is:
FIR(userdef,source,path)
●
Source is the input channel of the signal.
●
Path is a string containing the path and filename of the filter file. The file contains
the comma-separated filter coefficients.
► For example, to set a bandpass on channel 1 with filter coefficients saved in the
bandpass.csv file, enter:
FIR(userdef,Ch1,"C:\Users\Public\Documents\Rohde-Schwarz\RTx\bandpass.csv")
