2.2.2. PVA-3000 Meters: Overview
PhyView Analyzer metrology was introduced earlier in Section 1.3. In the following table, functional characteristics of
each of the PVA-3000 meters** are presented. Characteristics include applicable link rate, result units and formatting,
meter configurations, and support for single pair, multi-pair, and multi-port results.

2.2.3. PVA-3000 Meters and Link Rates
One important distinction between PVA metering relates to link rate (or link speed) management. Two meters, Link
Monitor and Tx Level, do not in any way attempt to force a particular link configuration. These meters respond to the
current link condition and report a result for that link condition. If the link is DOWN, they will report that condition.
The PSD and SNR meters support the selection of a link rate, either 100BaseTx or 1000BaseT, when configuring
and/or performing the measurement. So unlike Link Monitor and Tx Level, both of these meters may need to re-
configure a link prior to completing a measurement. Both meters will notify of a failure to establish the specified link
rate.
