Page 5: Introduction
Section 5 will cover the PSA Interactive user interface for the PSA-100-SA. Section 6 will introduce PowerShell and automated scripting capabilities available with the PSA-100-SA. The PowerSync Analyzer family from Sifos Technologies also includes the following products: • PSA-1200: Chassis-based analyzer with capacity to test up to 24 PSE ports. The PSA-1200 fully supports optional modules including the PSE Conformance Test Suite and the PSE Multi-Port Test Suite. - Page 6 PowerSync Service Analyzer Reference Manual February 8, 2010 Sifos Technologies page...

(802.3at) versus normal power (802.3af) type PD’s. PSE’s, including Mid-Spans, can furnish power on any pair (ALT A or ALT B) and an option may exist to allow powering of all 4 pairs under 802.3at. February 8, 2010 Sifos Technologies page... -
Page 8: Pd Detection
Classification is performed by applying a voltage in the band from 15.5V to 20.5V and measuring the fixed DC current load presented by the PD. The magnitude of measured current is then translated into a classification as follows: February 8, 2010 Sifos Technologies page... -
Page 9: Power-Up
Given the ceilings specified, an 802.3af compliant PSE might theoretically furnish a maximum of 22.7 watts while a 2-pair, high power, 802.3at compliant PSE might theoretically supply up to 38.9 watts continuous power. Practically speaking, typical port power capacity will be relatively close to the minimum required values. February 8, 2010 Sifos Technologies page... -

PD connections. On the other hand, the added complexity complicates testing by adding ambiguity as to exactly how a PSE is detecting either an 802.3 or other type of PD. February 8, 2010 Sifos Technologies page... -
Page 12: System Hardware Overview
When the PSE voltage reaches approximately 11 volts, the passive R-C Detection signature is removed and the MPS signature R-C circuit is inserted thus presenting a valid AC MPS signature following PSE power-up for as long as the Port Switch is closed (or connected).

Page 13: Triggers
Output triggers will appear as a 3.3V, 10 mSec pulse. When set as an input, it can drive the external trigger bus inside the PSA chassis. This enables triggering across multiple instruments, which may be desirable when testing equipment with more than 24 ports. February 8, 2010 Sifos Technologies page... -

Sifos does not specify any particular level of performance for the Data OUT port because performance is strongly influenced by physical layer design characteristics of LAN ports (e.g. packet data testers, PSE ports) that are connected to the PSA Test Ports.
