Suffix:

1..4
Parameters:
<IQInputType> REAL | COMPlex
REAL
Real RF signal. One real RF signal requires one input channel,
thus up to four real signals can be recorded in parallel.
COMPlex
Complex I/Q signal in baseband or low IF range. One complex
input signal requires two input channels. The In-Phase compo-
nent must be connected to channel 1 or 3, and the Quadrature
component must be connected to channel 2 or 4. Thus up to two
complex input signals can be recorded in parallel.
*RST: REAL
Usage: Asynchronous command
CHANnel<m>:IQ:INPMode <IQInputMode>
Selects the frequency band of a complex input signal.
Suffix:

Sets the bandwidth factor to define the filter bandwidth.
Filter BW = Relative BW * Sample rate
Parameters:
<RelBw> Range: 0.04 to 0.8
Increment: 0.01
