Filter:bbt; Filter:channel; Filter:type - Agilent Technologies N5171B Command Reference Manual

:FILTer:BBT

Supported N5172B/82B
[:SOURce]:RADio[1]:ARB:FILTer:BBT <value>
[:SOURce]:RADio[1]:ARB:FILTer:BBT?
This command changes the bandwidth–multiplied–by–bit–time (BbT) Real- Time Modulation filter
parameter.
The filter BbT value can be set to the minimum level (0.1), the maximum level (1), or in between by
using fractional numeric values (0.100 to 0.999).
*RST +5.00000000E001
Range 0.100 to 1.000
Key Entry Filter BbT
Remarks This command is effective only after choosing a Gaussian filter. It does not have
an effect on other types of filters.
To change the current filter type, refer to :FILTer:TYPE.

:FILTer:CHANnel

Supported N5172B/82B
[:SOURce]:RADio[1]:ARB:FILTer:CHANnel EVM|ACP
[:SOURce]:RADio[1]:ARB:FILTer:CHANnel?
This command optimizes the Nyquist and Root Nyquist Real- Time Modulation filters to minimize
error vector magnitude (EVM) or to minimize adjacent channel power (ACP).
EVM This choice provides the most ideal passband.
ACP This choice improves stopband rejection.
*RST EVM
Key Entry Optimize FIR For EVM ACP
Remarks To change the current filter type, refer to :FILTer:TYPE.

:FILTer:TYPE

Supported N5172B/82B
[:SOURce]:RADio:ARB:FILTer:TYPE RNYQuist|NYQuist|GAUSsian|
RECTangle|IS95|IS95_EQ|IS95_MOD|IS95_MOD_EQ|EDGE|EWIDe|EHSR|WCDMa|AC4Fm|"<user FIR>"
[:SOURce]:RADio:ARB:FILTer:TYPE?
This command specifies the Real- Time Modulation filter type.
RNYQuist This choice selects a Root Nyquist (root raised cosine) filter. This filter is adjusted
using Alpha.
NYQuist This choice selects a Nyquist (raised cosine) filter. This filter is adjusted using
Alpha.
