bladeRF: manual DC Offset and IQ Imbalance correction

	#!/usr/bin/python2
	#!/usr/bin/env python2
	#
	# This script puts the bladeRF into an RF loopback mode, transmitting
	# a vector at an offset from the RX frequency. The resulting image may be used
	# to manually dial in RX-side IQ imbalance correction. Sliders to minimize the RX
	# DC offset are also included.
