Getting down to business, National Instruments’ general-purpose digitizer/oscilloscope offers a 1 giga-sample per second (GS/s) real-time sampling rate on two simultaneous channels and 20 GS/s Equivalent Time-Sampling (ETS). NI chose National Semiconductor’s dual-channel ADC08D1500 1.5 GS/s analog-to-digital converter (ADC) for the module because of its performance and features. When using only one channel, the NI unit uses the ADC’s built-in interleaving mode with autocalibration to double the real-time sample rate. Key specs for the ADC include 7.25 effective number of bits (ENOBs) at an input frequency of 748 MHz and a bit error rate (BER) of 10-18.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Ear-based heart-rate monitoring gained momentum recently, as sensor maker Valencell Inc. announced it has licensed its biometric earpiece technology to Samsung Electronics Co. Ltd for use in so-called “hearable devices.”
