Digital Oscilloscope
12-bit oscilloscope reaches 65 GHz, tests high-speed links
The WaveMaster 8000HD series from Teledyne LeCroy goes where no 12-bit oscilloscope has gone before. Serial digital data streams never stop reaching for higher data rates. Buses such as PCIe Gen 6 (64 Gtransfers/sec) and USB4 V2 (80 Gb/sec) have gone to PAM4 and PAM3 modulation, respectively, to reach their current data rates. Two-level modulation […]
What specialist software is available for USB oscilloscopes: Part 2?
This FAQ looks at software that can synchronize multiple oscilloscopes, perform mathematical functions, and transform a basic USB oscilloscope into multiple instruments. A USB oscilloscope consists of signal capture and conditioning electronics, a personal computer (PC) that can be a laptop, tablet, or desktop, plus PC software. The availability of application specialist software is a […]
What specialist software is available for USB oscilloscopes: Part 1?
USB oscilloscopes capture analog and digital signals. Through software, engineers can analyze protocols and logic signals. By adding a D/A converter, a USB oscilloscope can also become a waveform generator. A USB oscilloscope consists of the signal capture and conditioning electronics package, a personal computer (PC) that can be a laptop or tablet unit, or […]
What is PCIe gen 6 and how do I test it? Part 2
PAM4 modulation boosts throughput but adds test challenges. Part 1 of this two-part series described the evolution of the PCI Express (PCIe) standard, including the move from non-return-to-zero (NRZ) signaling in PCIe 5 to four-level pulse-amplitude modulation (PAM4) signaling in PCIe 6. What unique test challenges does PCIe 6 present? As mentioned in Part 1, […]
What is PCIe gen 6 and how do I test it? Part 1
PAM4 modulation boosts throughput but adds test challenges. The Peripheral Component Interface (PCI) emerged in the 1990s as a parallel bus for connecting computer mainboards and peripheral devices. In 2003, a serial version called PCI Express (PCIe) debuted, with generation 1 offering a transfer rate of 2.5 GT/s. Over the past 20 years, successive generations […]
Automate double-pulse testing in WBG devices
By automating double-pulse testing of wide bandgap devices such as SiC and GaN power devices, you can cut setup and analysis time. The need to reduce carbon emissions drives investments in electrical technologies, particularly in data centers and electric vehicles. In its most recent Elective Vehicle Outlook report, Bloomberg estimates a 27% increase in global […]
Software tests PCIe 6.0 on high-end oscilloscope
Teledyne LeCroy has released a beta version of software for automating serial-data analysis on PAM4 signals. Engineers can request a copy. By using PAM4 modulation, PCIe 6.0 doubles data rates to 64 GT/sec (256 Gb/sec when using an x16 configuration). The “secret sauce” in the doubling comes from PAM4, which puts four voltage levels in […]
New oscilloscopes feature super-fast 4.5 M acquisitions/sec update rate
The new R&S MXO 4 series oscilloscopes feature the world’s fastest real-time update rate of over 4.5 million acquisitions per second. Development engineers can now see more signal detail and infrequent events than with any other oscilloscope. The 12-bit ADC in the R&S MXO 4 series has 16 times the resolution of traditional 8-bit oscilloscopes at […]
New 12-bit high-def oscilloscopes target high-speed signal integrity applications
The HDO Series of High Definition Oscilloscopes feature true 12-bit resolution and are available in 70 MHz – 800 MHz bandwidths and two or four channels. The HDO Series is powered by the new UltraVision III platform featuring a custom ASIC chipset, which also provides for dramatically lower front-end noise. The higher resolution and lower […]
