Preset
Initial S/W Revision
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.

Example
Initial S/W Revision
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.

Initial S/W Revision
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 imaginary part will always be zero, but for any other center frequency both the real and imaginary
parts will be significant. Note that since the receiver's real output is displayed as the "I" data, when the
center frequency is 0, the Q Only input appears as the "I" data.
