Fourth-gen SiGe process provides scope’s 60 GHz bandwidth

The LabMaster 10 Zi oscilloscope from LeCroy Corp combines combines patented digital bandwidth interleave (DBI) technology and the Zi ChannelSync architecture to deliver up to 60 GHz of bandwidth.

The scopes are the first to use a 36 GHz / 80 GS/s 8HP silicon-germanium (SiGe) chipset and provide up to twenty channels at 36 GHz and up to ten channels at 60 GHz.

A single LabMaster 10 Zi module provides four channels at 36 GHz bandwidth and further provides the ability to link up to five modules to provide 20 fully synchronized high-bandwidth channels.  

IBM's 8HP SiGe process is the fourth-generation SiGe process with two times the performance of the previous generation and provides lower electrical noise for increased performance and lower power consumption.

The DBI technology, provides the ability to double or triple the bandwidth available in raw silicon by splitting a high bandwidth signal into multiple paths of lower bandwidth and then re-assembling the separate lower bandwidth paths into a single high bandwidth path using digital signal processing (DSP).

The LabMaster modular oscilloscope architecture separates the oscilloscope signal acquisition function from the display, control and processing functions. Up to five LabMaster 10 Zi Acquisition Modules can be fully synchronized using LeCroy's ChannelSync architecture.

In addition to the 60 GHz and 160 GS/s sampling rate, analysis memory of 1024 Mpts/ch is provided.

Trigger bandwidth is 30 GHz – twice that of LeCroy's WaveMaster 8 Zi-A and LabMaster 9 Zi-A oscilloscopes, while jitter noise floor is 100 fs(rms) for the 50 and 60 GHz models. Rise time (20-80%) is 5.5 ps for the 60 GHz model, and 9.75 ps for the 36 GHz model.

Additionally, a 14.1 Gb/s 80-bit serial pattern trigger with support for 8b/10b and 64b/66b symbol triggering and PCI Express Generation 3.0 will be optionally available for LabMaster 10 Zi models. This trigger significantly enhances the value of LabMaster 10 Zi for high speed serial data debugging by providing ability to isolate errors to specific symbols and PCI Express link layer.

The LabMaster Master Control Module (MCM-Zi) contains the display, controls, ChannelSync architecture, and a server-class CPU. LabMaster 10 Zi Acquisition Modules, based on 8HP SiGe and DBI, provide silicon-based 36 GHz performance with up to 60 GHz on two channels. One LabMaster 10 Zi Master Control Module and one LabMaster 10 Zi Acquisition Module function as a single, conventional four channel 36 GHz oscilloscope, or as a conventional two channel 60 GHz and four channel 36 GHz oscilloscope. However, by using ChannelSync technology, up to five LabMaster 10 Zi Acquisition Modules can be synchronized,  extending the channel density performance by a factor of five to achieve up to 20 channels at 36 GHz and 10 channels at 60 GHz.

Models are also available with silicon-based 25 and 30 GHz of bandwidth, each with 80 GS/s sampling rate on each channel. A model with 50 GHz of bandwidth and 160 GS/s of sample rate on two channels is also available. This model also has silicon-based 36 GHz performance. All acquisition module models are used with the LabMaster 10 Zi Master Control Module for expandability in channel count, and all models may be upgraded in bandwidth at a later date to up to 60 GHz.

Customers who have LabMaster 9 Zi-A may mix and match those acquisition modules with the LabMaster 10 Zi models, preserving the customer's previous investment in LeCroy oscilloscopes.

Standard memory is 20 Mpts/ch (on all four channels, doubled when channels are bandwidth interleaved) with memory options of 32, 64, 128, 256 and 512 Mpts/ch. Maximum analysis memory of 512 Mpts/ch (36 GHz) and 1024 Mpts/ch (60 GHz).

LabMaster 10 Zi oscilloscopes start at $252,900, with acquisition modules priced from $156,000.
