Introduction
Reference software for performing multi-channel signal generation and acquisition with NI RF products.
Multi-channel in this case means each individual channel has its own LO source and can be tuned to a unique frequency.
Version 1.2.2 fixes an issue in the Acquisition software that could cause low memory option analyzers to experience a buffer overflow during stream-to-disk opertaion.

Changes from 1.2.1
- Fixes an issue in the Acquisition software that could cause low memory option analyzers to experience a buffer overflow during stream-to-disk opertaion.
Changes from 1.2
- Fixes a bug in the Generation software that caused single generation (i.e. non-looped) playback to generate part of the file twice, and output signal for a period of time longer than that represented by the data in the recorded file.
Changes from 1.1
- Skip NI-TClk configuration for single-channel use cases. This is not a fix for anything, rather a clarification that you don't need Ni-TClk for single channel usage.
- As a followon to the previous bullet, now use NI-RFSA/NI-RFSG Initiate for single-channel usage instead NI-TClk Initiate
- Improved interface for In-Band Retuning functionality. The user specifies a center frequency and optional LO offset for each channel. The sum of the center frequency and LO offset will determine the upconverter/downconverter center frequency and their subsequent LO frequencies.
- Tweaked the user interface / front panel, mainly reducing the size to accomodate lower resolution displays more conveniently.
