Multi-Port High Throughput Test Automation

The PSA-3000 and PSA-3048 are provided with a sample PSE automated test script, psa_quick_test, that recovers critical PoE parameters from PSE test ports with an effective test throughput of less than 15 seconds per tested port. This application can be used in both QA and manufacturing test to rapidly qualify PSE functional performance.

Important features of the psa_quick_test include:

  • Source Code Provided: May be used as, may be modified, or may be used as template script
  • Tests Type-1, Type-2 (2-event), and Type-2 (LLDP*) PSE’s
  • Validates PoE Detection Acceptance and Rejection Ranges
  • Measures PSE Port Voltage at minimum and maximum load conditions
  • Determines Power Capacity in Watts and mA
  • Assesses Disconnect Power Removal response and timing
  • Assesses Overload Power Removal and Power-Type Threshold
  • Assesses LLDP Power Allocations* and associated timing

Typical test times will range from 8 to 14 seconds per port tested, even when testing Type-2 LLDP capable PSE’s. With the PSA-3048, test times can be further reduced by controlling separate chassis’ from separate PowerShell’s allowing up to 16 ports to be tested concurrently.

*Note: LLDP PSE testing requires PoE LLDP Emulation and Analysis feature.

Low Cost, Fast Multi-Port PSE Testing

The PSL-3000 and PSL-3024 are provided with a sample PSE automated test script, psl_quick_test, that recovers critical PoE parameters from PSE test ports with an effective test throughput of less than 30 seconds per tested port. This application can be used as is, or with user modifications, in both QA and manufacturing test to rapidly qualify PSE functional performance.

Important features of the psl_quick_test include:

  • Source Code Provided: May be used as is, may be modified, or may be used as template script
  • Scans 4 to 8 PSE ports per test cycle
  • Tests Type-1, Type-2 (2-event), and Type-2 (LLDP*) PSE’s
  • Validates PoE Detection Acceptance and Rejection Ranges
  • Measures PSE Port Voltage at minimum and maximum load conditions
  • Determines Power Capacity in Watts and mA
  • Assesses Disconnect Power Removal response
  • Assesses Overload Power Removal and Power-Type Threshold
  • Assesses LLDP Power Allocations*

*Note: LLDP PSE testing requires PoE LLDP Emulation and Analysis feature.

PSL-3000 Datasheet

PSL-3000 Low Cost-per-Port Programmable Load

The PSL-3000 Programmable Load is a low-cost, one-box solution to facilitate testing and analysis of IEEE 802.3at Power Sourcing Equipment (PSE) behaviors. Each test port inside a PSL-3000 is an autonomous and fully isolated instrument offering stimulus and measurement resources. Test ports are configured and controlled via a high level automation interface, PowerShell PSA, and may also be rapidly accessed and managed from an intuitive graphical user interface, PSA Interactive PL.

  • Multi-Port Precise PSE Loading & Measurements
  • Static PSE Loading > 42 Watts per Port x 24 Ports
  • DC Voltage, Current, and Power Metering
  • Low Cost-per-Port
  • Flexible and Efficient Script Automation and Debug Environment
  • Optional Powered Device LLDP Emulation
  • Enables PSE Packet Transmission Testing with PoE Loads
  • Smart Fan Control – Runs Cool and Quiet
  • Thorough Documentation and Sample Programs

PowerShell PSA Script Automation

The PowerShell PSA Scripting Environment provides a high level, live-keyboard means to control and program automated test sequences for the PSA-3000 PowerSync Analyzer family. PowerShell PSA enables fully automated testing suites that span multiple ports, blades, and frames. Built upon the popular Tool Command Language (Tcl), it offers an extensive and extensible programming language.   

PowerShell PSA provides a complete API for Sifos PowerSync instruments including high level commands that execute and sequence standard 802.3at PSE Conformance and Multi-Port System test suites. PowerShell PSA commands access all of the resources of each test port and enable the rapid development and debug of highly customized test scripts. PowerShell fully supports off-line script development and debug through its robust built-in emulation mode.
  • Popular Tcl/Tk Scripting Language Foundation
  • PSA-3000/PSL-3000 specific commands, queries, and utilities
  • Command Line Help for all commands
  • Interactive Command / Query / Command-Sequence execution and debug
  • Options for control from outside software environments
