One of the unique features of the USB-UT350 is the on-board DSP from Texas Instruments. It is capable of processing data at high speeds for real time peak detection, data compression, spray marker control, as well as factory process control and feedback. Another benefit of the DSP is that the device can also run in standalone operation mode as a remote pulser/receiver and data processing system. When used in standalone operation mode the device does not need to be connected to a computer. The device will remember the stored configuration and operate independently, powered either by an AC adapter or optional battery pack. It is capable of providing feedback through the internal speaker and digital I/O pins to indicate flaws or measurements outside of the specified thickness range.
The signals from the WPT-Pre (AC) are fed to the HFA via the differential buffer amplifiers in the EWO-WFC/OFA(E). In addition, the signal from the MSC-PA is fed directly to the HFA, which consists of two channels of analog receiver (HFA-A) and digital circuit (HFA-D) for signal processing. In the HFA-A, two signals from two electric field sensors (i.e., Eu, and Ev) and one magnetic field sensor (B γ ) are selected and fed to two receiver channels. The receivers consist of attenuators (0 or 10 dB), HPF, and LPF. The passband of the receiver is from 10 kHz to 10 MHz. The analog signals are sampled by an A/D converter in the HFA-D with a 25-MHz sampling rate. The spectra are obtained in two signal processing modes by field-programmable gate array (FPGA) in HFA-D. In the 10-MHz mode, a fast Fourier transform (FFT) is directly applied to the 2048 digital waveform data points. In the 1-MHz mode, a cascade integrator-comb (CIC) filter with a passband below 1 MHz and decimation are applied to the signal from A/D converter, resulting in waveform data at 2.5 mega-samples per second (MSPS). FFT is applied to the 2048 points of the 2.5 MSPS waveform. Detailed specifications including a block diagram of the HFA are presented in Kumamoto et al. (2018).

Table 5a, b shows lists of PWE data produced as continuous data and burst data, respectively, with observation modes and their specifications. For details of product contents, please refer to the following papers: EFD in Kasaba et al. (2017), WFC and OFA in Matsuda et al. (2018) and HFA in Kumamoto et al. (2018).
The BAF system uses cell based transmission techniques over a passive optical network with tree and branch topology. Simple baseband intensity modulation and a time division multiple access algorithm are used. As explained in Chapters 3.2 and 3.3 the transmission in the upstream direction is of the burst mode type. This has serious consequences for the transmitter in the ONU and the receiver in the OLT; which cannot be constructed in the same way as those in the conventional systems used for the downstream direction.
GN25L95 is a low-cost combined burst mode laser driver and limiting amplifier designed for gigabit passive optical network (GPON) optical networking unit (ONU) applications. GN25L95 features automatic extinction ratio control for reliable operation of the laser over all conditions. A high accuracy auto-ranging A/D converter and on-chip temperature sensor give precise diagnostic reporting. 2ff7e9595c
