Scopes acquire elephantine memories
LeCroy has again set the record for the longest commercially available acquisition memory with a new option for its SDA, DDA and WaveMaster series oscilloscopes.
LeCroy has again set the record for the longest commercially available acquisition memory with a new option for its SDA, DDA and WaveMaster series oscilloscopes The new memory option increases the acquisition memory to 100Mpoint on each of two channels or 50Mpoint on each of four channels

Analysers take on high-speed serial data
LeCroy has released what it reckons are the world's first serial data analyser instruments.
Scopes claim top performance from 1 to 3GHz
The new WavePro 7000, 7100 and 7300 DSOs incorporate LeCroy's patented X-Stream technology and advanced WaveShape analysis capability at a price point with broad appeal.
This new memory option for the WaveMaster DSO provides signal capture capability that is unmatched by any competitive product.
With 50 million points of acquisition memory per channel (or 100 million when using two channels), a LeCroy instrument can maintain 10Gsample/s sampling rate for 5ms and can also digitise at 20Gsample/s for 5ms on two channels.
This means a LeCroy scope with XXL memory can sample 100 times faster than other scopes on the timebases where engineers are capturing long complex data streams, and offers more than three times the memory of its nearest competitor on two channels.
In addition to increasing the length of the acquisition memory the maximum number of segments available in sequence mode has been increased to 25,000.
The great advantage of this long acquisition is felt in applications such a serial data communications where an entire 223 pseudo random binary sequence (PRBS) pattern can be acquired in a single acquisition.
This means that pattern dependencies, such as inter-symbol interference (ISI) can be observed for the entire sequence.
Likewise, jitter studies can assess timing un-certainties down to 200Hz at the highest resolution of 50ps/point.
The WaveMaster series scopes use silicon-germanium (SiGe) memories which update at 3.3Gsample/s.
In a standard scope three memories are coupled to each digitiser realising a 10Gsample/s sample rate per channel.
When the -XXL memory option is installed the memory is doubled and six memories are coupled to each ADC.
This allows the scope to use 100Mbyte of memory.
