Filter Type(Meter)
Sets the RBW filter type.
Remarks:
 The RSA3000E series supports two kinds of RBW filters: Gauss and EMI.
 When the EMC measurement standard is "CISPR", the Filter Type(Meter)
menu is grayed out and disabled. By default, EMI filter is selected. When "EMI"
is selected, resolution bandwidth can only be 200 Hz, 9 kHz, 120 kHz, or 1 MHz.
 When the EMC measurement standard is "None", the default filter is "Gauss".
