Note
This specification holds at the center frequency of the transmitted
instantaneous bandwidth, 100 MHz maximum after the device performs a recent
single point I/Q impairment self-correction. The measurement is performed with
0 dB of TX attenuation.

1
Tuning resolution combines LO step size capability and frequency shift DSP
implemented on the FPGA.
2
Enable fractional mode and use a 100 kHz LO step size with all LO step size specifications.
3
This settling time specification only includes frequency settling time, and it excludes
any residual amplitude settling that may occur as a result of large frequency changes.
Driver and operating system timing can affect transition times. This specification
reflects only hardware settling.
