Picosecond Pulse Labs, Inc. is a leading designer and manufacturer of instruments, modules, and components for test & measurement and serial communications. Picosecond's core competence is generating, receiving, and measuring high-speed analog signals. A key part of this competency is our in-house GaAs and thin-film fabrication facility. Our capabilities enable a broad range of products including TDR/T instruments, ultra-fast pulse generators, 100 GHz samplers, and broadband components.

The Picosecond Pulse Labs' Model 4022 TDR/T pulse source works with standard commercial TDR/T systems to provide faster TDR and TDT pulses. The 4022 provides 9 ps TDR pulses and 7 ps TDT pulses. These fast pulses increase TDR resolution and TDT bandwidth by 3X to 4X over standard systems. In addition to standard TDR and TDT analysis, the increased pulse speeds provided by the 4022 enable higher bandwidths for S-parameter analysis based on time domain measurements. Time domain based S-parameter analysis has the benefits of being both true differential and being significantly less expensive than frequency domain alternatives.

The Picosecond Pulse Labs' Model 4005 5 ps Pulse Calibration Source was designed specifically for the purpose of calibrating Real Time and Digital Sampling Oscilloscopes. The Model 4005 provides an extremely fast pulse edge with long flat top and bottom lines. The 5 ps edge of the 4005 is even fast enough to calibrate modern leading edge Digital Sampling Oscilloscopes with bandwidths of 70-100 GHz. The Model 4005 may also be used to deconvolve the response of either a Real Time or Digital Sampling Oscilloscope and increase the overall measurement bandwidth of the oscilloscope.

The Model 5317 BALUN is a bi-directional passive circuit that may be used to transform a single ended signal to differential and vice versa. This functionality may be used for making differential network analysis measurements using a single ended VNA. Two Model 5317's are simply placed in series with the ports of the VNA and they are characterized during the calibration process. Since the 5317 is passive and bi-directional, both forward and reverse measurements may be made. The Model 5317 may also be used to create a differential data stream from a single ended source. The 5317 also has built-in bias circuitry to provide appropriate offsets as required.
