Initial S/W Revision Prior to A.02.00
I+jQ
Sets the signal input to be both the I and Q channels. The I and Q channel data will be combined as I + j * Q.
Key Path
Input/Output, I/Q, I/Q Path
Example Set the input to be both the I and Q channels, combined as I + j * Q.
FEED:IQ:TYPE IQ
Initial S/W Revision Prior to A.02.00
I Only
Sets the signal input to be only the I channel. The Q channel will be ignored. The data collected is still
complex. When the center frequency is 0 the imaginary part will always be zero, but for any other center
frequency both the real and imaginary parts will be significant.

Example Set the input to be only the I channel.
FEED:IQ:TYPE IONL
Initial S/W Revision Prior to A.02.00
Q Only
Sets the signal input to be only the Q channel. The I channel will be ignored. The Q channel will be sent to
the digital receiver block as Q+j0. The receiver's output is still complex. When the center frequency is 0 the
