Agilent Introduces The United States Can Adjust The Bandwidth Of The Oscilloscope

Agilent Technologies introduced the United States 8 2GHz ~ 13GHz bandwidth determination of "InfiniiumDSO80000B" series Oscilloscopes

. For high-speed serial interface technology research and development, the maximum bandwidth is determined can be extended to 13GHz. Product selling point is the ability to reduce replacement costs. For example, the object will be developed from the existing PC I Express to more high-speed Generation 2 PCIExpress usually need to be priced at about 700 million yen, a bandwidth of 6GHz oscilloscope into a price change of about 12 million yen, for the 12.5GHz band oscilloscope. By upgrading the product, no need to replace the machine can expand the bandwidth. At this point the additional costs can be controlled within about 6 million yen.

In fact, this product is in the hardware General , The use of software users by limiting the bandwidth available to provide a variety of models of 2GHz to 13GHz. Upgrade the software through the lifting of restrictions and amendments can expand the bandwidth determination. In addition, because the machine is combined with the determination of the factory product testing bandwidth, so bandwidth is measured after the update may cause some internal lack of board performance. At this point we should replace the board. DSO80000B Series is equivalent to Agilent "DSO80000A" series (8GHz ~ 13GHz) and the "54850A" series (2GHz ~ 7GHz) follow-up model. And broadband products DSO80000A series, the use of the oscilloscope can reduce errors and trigger jitter of the technology, compared with the 54850A series reduces noise. The products such as the 6GHz (DSO80000B), when measured by 5mV/div resolution, GND of the RMS error of 241 V. Agilent old products (54850A) under the same conditions as 376 V.

This product with the maximum operating frequency of 2.93GHz microprocessor. From the analysis and processing for the use of old compared to 1GHz microprocessor, the processing speed is about 2.3 times. Display using the touch Panel . Prices, measured bandwidth of 2GHz the DSO80204B to 2,604,989 yen; 13GHz of DSO081304B to 13,722,541 yen.

Can trigger pulse width of 70ps

Agilent also introduced a waveform retrieval software "InfiniiScan". Achieved under the oscilloscope to capture Memory The data to detect abnormal wave "software trigger" function. Positioning the company to it is: trigger for increased time resolution (temporalresolution) products. For example, the use of intermittent surges triggered signal, the product can detect the pulse width of 70ps small surge. In the past, the hardware trigger, the resolution is only about 300ps. Pulse width should be observed smaller surge when the data is read into memory, one by one on the picture for visual.

Software trigger the need to write time and memory retrieval time, so theoretically speaking, can not be measured in comparison with the hardware trigger time (stop time) to be longer. However, because the original can not detect the hardware trigger requires the determination of 10GHz signal, so the product on the use of a software trigger. As InfiniiScan use, Agilent envisaged in the high-speed serial interface specifications Test The results appear in the process failed when used to find errors. In this case, since the appearance of abnormal wave frequency is not low, so use the software trigger can meet most requirements.

Addition to checking surge, it can also detect a complex phenomenon. Such as use of DDR memory interface, can the data strobe (strobesignal) and the difference between the edge data signals to determine fault is generated when the read, write or arising. In addition, mask testing, as done can be set to trigger the waveform by or through an area, can also be set to trigger the serial signals up to 80 images. Prices, support Infiniium80000 series "N5414A" to 575,689 yen.
