IEEE-1394b (Beta) Signaling Test Tools
BETA SIGNALING Testers
QP provides signal integrity/cable power test tools and debug fixtures for IEEE-1394 Data/Strobe (DS) and IEEE-1394b Beta implementation. DS and Beta signaling have drastically different signaling characteristics therefore QP offers specific test tools to meet the requirement of both. Please remember that most 1394b PHY implementations are bilingual, therefore they support both Data/Strobe and Beta signaling. To insure your implementation meets all requirements both DS and Beta signaling should be tested.
QP-SQT - Signal Quality Tester for IEEE-1394b (Beta)
QP's Signal Quality Tester (formerly QP-JSFSQT) is built upon a scalable platform with a VersaPHYTM backchannel and targeted at Beta signal quality testing. Engineered to conveniently test both transmitter signal integrity and receiver sensitivity the SQT automates both sets of tests. QP-SQT requires Windows XP, MS-Excel 2003, and GPIB support. National Instruments GPIB support is recommended. Please contact QP for the lastest list of supported oscilloscope models from Agilent, LeCroy, and Tektronix.
Receive Tester
- Receiver sensitivity
- Real world Bit Error Rate (BER)
- Receiver margin
The SQT’s Receive Tester (SQT-RT) conditions real world signals to provide worse case amplitude. By stressing the input of the device under test (DUT) in this manner a comprehensive receiver test can be done quickly and inexpensively. The SQT-RT is designed to test up to 3 port devices during one test run. SQT-RT is also designed to provide a first order indication of BER in approximately 3 minutes per port when directly connected to the DUT. QP provides a variety of cables to the SQT-RT's 9-pin connectors (38999, HSD, USCAR, RJ-45, etc...).
SQT-RT measures the following parameters:
Transmit Tester
- Baud rate
- Differential amplitude
- Rise/Fall time
- Eye diagram with mask
- Jitter
- Differential skew
- Common mode voltage
The SQT's Signal Integrity Tester (SQT-SIT) is used to test the output of the device under test (DUT). The data acquired from the oscilloscope is post processed using commonly available and inexpensive MS-Excel 2003. The flexible post processing method allows for Near End and Far End measurements. Additionally, the IEEE-1394b and SAE AS5643 parameters are used to qualify the results. Using the appropriate Test Fixture all ports of the DUT are tested. QP provides automation support for several oscilloscopes. Please contact QP for the most up-to-date list of supported oscilloscope.
SQT-SIT measures the following parameters:
QP-SIGKit4B Rev. C - Beta Signal Integrity Kit revision C.
QP's Beta Signal Integrity Tester is built upon a scalable platform with a VersaPHYTM backchannel and targeted at Beta transmit signal integrity testing. The Beta Signal Integrity Tester performs the same measurements as the SQT-SIT part of QP-SQT. QP-SQT requires Windows XP, MS-Excel 2003, and GPIB support. National Instruments GPIB support is recommended.
QP-SIGKit4B Rev. C is used to test the output of the device under test (DUT). The data acquired from the oscilloscope is post processed using commonly available and inexpensive MS-Excel 2003. The flexible post processing method allows for Near End and Far End measurements. Additionally, the IEEE-1394b and SAE AS5643 parameters are used to qualify the results. Using the appropriate Test Fixture all ports of the DUT are tested. QP provides automation support for several oscilloscopes. Please contact QP for the most up-to-date list of supported oscilloscope.
QP-SIGKit4B Rev. C measures the following parameters:

- Differential skew
- Common mode voltage
QP-ICT - Beta Interconnect Tester
The Quantum Parametrics’ Interconnect Tester (ICT) provides the ability to test one (1) to five (5) interconnects simultaneously. A interconnect could be a cable, cable with slip-ring, or a series of devices that include a 1394 PHY. Each ICT connection provides outputs with amplitude control. Each output maybe individual calibrated and controlled for maximum configurability. Each port transmits packets to the 1394 bus and receives data from the 1394 bus. Each packet is verified by the receiver of the packet. Currently there are S400 (QP-ICT-4) and S800 (QP-ICT-8) versions of the ICT. The S400 and S800 indicate the maximum data rate supported. The default configuration for the ICT is capacitive coupled for both the -4 and -8. QP-ICT requires Windows XP.
The ICT application communicates with the ICT instrument via VersaPHYTM (the Backchannel). The host computer must provide a 1394 open host controller interface (OHCI). PCI, PCMCIA, and integrated OHCI are acceptable. The ICT has one bilingual (port 1) and two beta only ports (port 0 and 2). The Backchannel uses VersaPHY technology for communication between the PC and the ICT.
