Keysight M8195A Revision 2 – Arbitrary Waveform Generator User’s Guide    211 
Set or get the predefined FIR filter type for a channel to be used when the Sample 
Rate Divider for the Extended Memory is 1. 
  LOWPass – equiripple lowpass filter with a passband edge at 75% of 
Nyquist 
  ZOH – Zero-order hold filter 
  USER – User-defined filter 
The command form modifies the FIR filter coefficients according to the set filter type, 
except for type USER.  
Command: 
OUTP:FILT:FRAT:TYPE LOWP 
 
 
6.13.9  :OUTPut[1|2|3|4]:FILTer:FRATe:SCALe[?] <scale>|MINimum|MAXimum 
 
:OUTPut:FILTer:FRATe:SCALe[?] 
Set or get the FIR filter scaling factor for a channel to be used when the Sample Rate 
Divider for the Extended Memory is 1. The range is between 0 and 1. 
Command: 
OUTP:FILT:FRAT:SCAL 0.9 
 
 
6.13.10  :OUTPut[1|2|3|4]:FILTer:FRATe:DELay[?] <delay>|MINimum|MAXimum 
 
:OUTPut:FILTer:FRATe:DELay[?] 
Set or get the FIR filter delay for a channel to be used when the Sample Rate Divider 
for the Extended Memory is 1. The range is -50ps..+50ps. The delay value has only 
effect for filter type LOWPass. 
The command form modifies the FIR filter coefficients according to the set delay 
value.
