which low level spurs can degrade the AD9864’s sensitivity

performance.

Despite the many spurs, sweet spots in the LO frequency are

generally wide enough to accommodate the maximum signal

bandwidth of the AD9864. As evidence of this property,

Figure 68 shows that the in-band noise is quite constant for LO

frequencies ranging from 70 MHz to 71 MHz.
