This mode is available for offset frequencies smaller than 30 kHz.
Note that you have to
●
turn on decimation with [SENSe:]IQ:DECimation
●
select the I/Q FFT mode for the affected half decades with [SENSe:
]BANDwidth|BWIDth[:RESolution]:TYPE
●
turn off forward sweep with [SENSe:]SWEep:FORWard
Parameters:
<State> ON | OFF | 1 | 0
Example:
SWE:FORW OFF
LIST:RANG9:FILT:TYPE IQFF
LIST:RANG8:FILT:TYPE IQFF
IQ:DEC ON
