Command

[:SENSe]:EVM:FILTer:REFerence RCOSine | RRCosine | GAUSsian | RECTangle |

HSINe

[:SENSe]:EVM:FILTer:REFerence?

Example

:EVM:FILT:REF GAU

:EVM:FILT:REF?

Notes When the Half Sine filter is selected, the Alpha control will be set to 0.9 and grayed out

This control enables you to determine the filter characteristics of the Raised cosine

and Root-raised cosine filters used by the analyzer's digital demodulator. These

characteristics apply to both of the Ref filters.

Remote Command

[:SENSe]:EVM:FILTer:ALPHa <real>

[:SENSe]:EVM:FILTer:ALPHa?

Example

:EVM:FILT:ALPH 0.5

:EVM:FILT:ALPH?

Dependencies This control is available for Raised Cosine and Root Raised Cosine filters only
