IEEE1588 PTP Time Tester/Analyzer

BPT-001 IEEE1588 Test Set is a portable instrument designed to help the development and deployment of the time synchronization technologies, especially IEEE1588 PTP (Precision Timing Protocol) based devices and systems.

BPT-001 Test Set supports high precise measurement reference clock, which can be synchronized to absolute time such as GPS (Global Positioning System), Galileo, BD-Star (Chinese version GPS system) systems. The reference clock can also be synchronized to external time by external GPS interface or IRIG-B interface. This design makes BPT-001 Tester Set can be used to test absolute timing (reference to absolute time), or relative timing(reference to local reference time).

BPT-001 Tester Set can be used to monitor, capture, store, analyze timing messages. IEEE1588 PTP messages, IRIG-B-DC, IRIG-B-AC, IRIG-B- Modified Manchester coded timing code, and serial (EIA-232 or EIA-422) timing messages are supported.

BPT-001 Tester Set can monitor, capture, store, analyze timing pulses. Multiple PPS (pulse per second), PPM (pulse per minute) signals can be tested against the reference clock, and errors against the high precise reference clock can be measured. BPT-001 Test Set can measure frequency, pulse width, and SOE (Sequence of Event).

Synchronization often takes a period of time to progress to the lock state. During this period of time, quite some message exchanges and adjustments are in progress. To help watch the whole process, all data collected during the test on the BPT-001 Test Set can be saved into USB disk, and be replayed. This feature even includes the Digital Scope function. While in scope mode, BPT-001 saves the sampled data into the USB Disk frame by frame. When in relaying, each stored frame of data can be recalled and checked to determine any hidden issues.

For high speed Ethernet traffic, traditional scope is powerless. BPT-001 Test Set PTP protocol analyze function can be used to capture and analyze all PTP messages, to help solve any PTP message problems. All captured messages are time tagged at nano-second level, and can be stored into the USB disk for replay and detailed analyze.

When BPT-001 Tester Set don't need to be worked as the PTP system components, it can work at passive mode at back ground, just collect and analyze the PTP message exchanges.To support BPT-001 Test Set's various functions, settings and options are used to control the features, such as which version of PTP to use, or which channels are enabled to measure timing errors, or from which channel the IRIG-B test signal is connected. BPT-001 Test Set support easy ways to change these settings and options, and once changed, BPT-001 Test Set will automatically remember them, and recall at next visit to the function.

BPT-001 IEEE1588 Tester Set supports both IEEE1588 PTP protocol specification version 1 (IEEE Std 1588-2002, IEC61588 2004-09) and specification version 2 (IEEE1588-2008). For version 2, P2P or E2E delay measurement schema modes are supported. When work in master mode, BPT-001 Test Set supported both P2P and E2E, and will automatically adapt to the slave's delay measurement mode.

IWhilst carrying out the test and measurement functions, at the same time in the back ground, BPT-001 can be set to work as or to simulate any part of the PTP synchronization system components, to generate or pass through needed PTP network traffic. BPT-001 Test Set can work as PTP Grand Master Clock, PTP Slave Clock, PTP Boundary Clock, and dual port PTP enabled Ethernet switch. For example, to test a PTP Master Clock, BPT-001 Test Set can be set to work as a PTP Slave Cock to inter change PTP message with the Master Clock under testing, to check its functionality.
