I second Peter's suggestion. VisLM-C does a great job, is widely compatible and is cheaper than most other options. Plus, Nugen really have established themselves as the broadcast metering and limiting specialists and they closely follow each standards revision. Updates are online days after revision at the most, not weeks as with some other developers. Most other options are expensive, have limited compatibility depending on software versions or imply that you're already drinking the developer's authorization kool-aid.
The VisLM-H version has histogram metering and data logging facilities the VisLM-C version lacks but, in my experience, The Compact version more that enough for almost all situations.
