In this world exclusive episode, Shahriar visits Teledyne LeCroy to take a close look at the operation, teardown and experiments with the LabMaster 10-100zi, 100GHz simultaneous bandwidth, 240GS/s real-time oscilloscope. This instrument provides either a single 100GHz channel, or two 33GHz and one 65GHz digitizing channels. The instrument uses a frequency interleaving technique invented and implemented at LeCroy.

The block diagram and the theory of operation of the scope is presented. This includes the architecture of the 4x80GS/s ADCs and the triple frequency interleaving system. The teardown of the scope includes a close look at the ADC platform, the dual frequency interleaving (65GHz operation) and the triple frequency interleaving (100GHz operation). The experiments with the scope demonstrate the instrument's capability to digitize signals up 100GHz using the beat frequency of two non-coherent lasers. The scope is also used to capture a 4pS rise time pulse from a femtosecond laser pulse system and a high-speed photo detector.
A complete factory tour is also presented where Teledyne LeCroy assembles all their oscilloscope products right here in the USA.
