Laser Based Position Measurement System
Laser Based Position Measurement System Customer Case In order to test their Laser Based Position Measurement Systems, the customer needs to characterize an output pulse from his circuitry which lasts for approximately 5 microseconds. According to the customer's estimates, he must use a sampling rate of 50 MSPS or higher in order to be able to analyze the signal completely. An additional requirement of the test system is that a specific number of successive pulses be digitized and then averaged in order to eliminate system noise. The number of such successive pulses must be variable. The repeat rate of [...]
High-Power Laser Lamp Array Tester
High-Power Laser Lamp Array Tester Customer Case The customer is building a tester for an array of high-power laser lamps. These lamps draw 35,000 Amps of current. The test involves sending a control signal to the laser lamp and measuring the time between the signal and the switching on of the lamp (which is picked up by a photodiode). This time is representative of the quality of the lamp. The customer currently has a 16-channel system, and would like to explore increasing the number of channels. In the customer's present system, eight CompuScope 512 cards are installed in a [...]
Synchronizing Over A Wide Sampling Speed Range
Synchronizing Over A Wide Sampling Speed Range Customer Case The client has set up an experiment where he needs to generate a stimulus signal and apply it to a He-Ne Laser with some polarizing optics. The response signal is a measurement of the Faraday effect. The signal is noisy and requires averaging over a very long time. The stimulus and response must be synchronized over a wide frequency range. For synchronization, the application requires a wide band of sampling speed from, 1 KS/s to 50 MS/s. GaGe Case Solution While GaGe's CompuScope 14100 provides the required digitizer performance, it [...]

Time Resolved Spectroscopy of Protein Crystals
Time Resolved Spectroscopy of Protein Crystals Customer Case The customer is involved in Time Resolved Spectroscopy of protein crystals. This involves shooting a laser onto the protein crystals and measuring the pulses generated by the crystals (as they are projected out of the sample) and their decay over time. Due to the very noisy nature of the return signals, it is essential to average many pulses in order to recover the pulse shape and measure the decay. The decay takes place over many tens of milliseconds, so it is necessary to acquire very long records (in the order of [...]
Hyper Remote Laser Sensor
Hyper Remote Laser Sensor Customer Case The customer is at the prototype stage for building a hyper remote sensor which will fly over the ocean and be able to see 100 to 200 feet below the surface. The sensor is being designed in order to determine the composition of the ocean and the ocean floor. This remote sensor will be extremely useful in the detection of pollution and studying the way pollution is being distributed by ocean currents. It will also be useful to the military (navy) for creating mine-finding systems. A deep blue laser will be used to [...]
GaGe White Paper: ENOB: The Best Digitizer Performance Metric
Introduction Figure 1. GaGe High-Speed Digitizers including PC Oscilloscope Software, powerful SDKs for custom application development and turnkey integrated PC-based measurement systems. While the nominal vertical resolution of a high-speed waveform digitizer (specified in bits) is often promoted, its true performance is provided by its measured Dynamic Parameters and in particular by its Effective Number of Bits (ENOB). This article describes measurement of the Dynamic Parameters and presents measurements for a leading-edge GaGe 12-bit Digitizer. A widely used digitizer-like device, the Digital Storage Oscilloscope (DSO), is optimized for the visualization of unknown signals. The relatively [...]
Laser Induced Fluorescence (LIF)
Laser Induced Fluorescence (LIF) Customer Case A customer has developed a breakthrough technique for the application of laser-induced fluorescence (LIF) detection to high performance liquid chromatography, capillary e lectrophoresis, sequencing and microbial analysis. The technique involves using fluorescence decay curves at multiple wavelengths simultaneously, leading to true 3-D fluorescence spectroscopy (i.e., fluorescence intensity as a function of wavelength and delay time relative to pulsed excitation). They have a requirement to increase the laser pulse repetition frequency (PRF) from 20-50 pulses per second to 500-1000 pulses per second. Basically, they want to collect and time resolve the fluorescence signal for [...]
Optical Spectroscopy
Optical Spectroscopy Customer Case A customer who is completing his doctorate in Chemistry at the California Institute of Technology has identified the need to measure fast optical signals using fast photo-detectors. The signal pulse width is as short as 2ns. Signals will be acquired at a 1KHz repetition rate, with a record length of 1,000 to 10,000 data points. GaGe Case Solution The CompuScope 82G, an 8-bit, 2GS/s A/D and Scope card for PCI Bus, is the best solution for this customer. With relatively small record sets, the customer is able to keep up with the 1KHz Pulse Repeat [...]
