NI RF Multi-Channel 1.2.2

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.

Supported Hardware

     Acquisition

  • PXIe-5663
  • PXIe-5663E
  • PXIe-5665 (3.6 GHz)
  • PXIe-5665 (14 GHz)

     Generation

  • PXIe-5673
  • PXIe-5673E

Dependencies

     Acquisition

  • NI LabVIEW 2010 or later
  • NI-RFSA
  • NI-RFSG
  • NI-Sync
  • NI Modulation Toolkit
  • NI Spectral Measurements Toolkit

     Generation

  • NI LabVIEW 2010 or later
  • NI-RFSG
  • NI-Sync

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.
