The GLA-1000 Series is a palm-sized PC based logic analyzer with functionality matching that of a desktop device. A maximum of 32 channels, 32Mbits of data memory (GLA-1032), a 200MHz internal sampling rate, and advanced trigger settings provide high accuracy and lengthy data analysis results. Features, such as Data-loss-less compression, Enable Qualifier, and Serial Bus Protocol Analyzer, provide you with a tool to adequately analyze today's complex digital systems. All data and configurations can be saved into a PC for further data analysis. The GLA-1000 Series operates over a high-speed USB 2.0 connection and is fully powered by the USB bus.
High-Speed Signal Acquisition and Measurements
With 200MHz internal sampling rate, the timing analysis of GLA-1000 Series conforms even to today's cutting edge digital technology. The 100MHz external sampling rate gives user high confidence in performing table and synchronized state analysis. The maximum 1Mbits of data memory per channel, enhanced by up to x 255 data-loss-less compression, enables longer data acquisition and deeper data analysis. The channel grouping could be done randomly based on the user-defined configuration, which provides flexible channel arrangements for sophisticated digital measurements.
Advanced Trigger Functions
The trigger setting could be done either from a trigger selection soft key in front of each channel display for individual channel setting or through a dialog window for pre-defined Bus pattern setting. The selection of trigger conditions include high , low, rising edge, falling edge, either edge and don't care for all channels or a Binary , Decimal or Hexadecimal code of a pre-defined Bus. The userselectable threshold, in TTL, CMOS, ECL and userdefined voltage (-6.0V~+6.0V), allows quick adoption of measurements on a multi-voltage digital system. Like a modern DSO , GLA-1000 Series features advanced trigger functions , including time delay trigger, clock event delay trigger, page delay trigger and Post/Pre trigger display. The unique feature "Enable Qualifier" picks up only the portions of data that match the user pre-defined condition after the signal being triggered. This function effectively reduces the redundant data and collects as much as possible the useful data sections within the limited memory. Three control signal output terminals, Start, Trigger & End, are provided to facilitate the control over external devices. When GLA-1000 Series triggers on a signal, its trigger output signal could activate a DSO to get asynchronized real-time waveform for the cross reference of digital data and analog signal waveform.This is a typical example among all the applications of control signal outputs.
Powerful Data Analysis Capability
A data-search dialogue window helps finding the user-defined data from the chunky data stream acquired after triggering. A bar cursor automatically locates the found data pattern and put it to the screen center. The additional bar(s) could be used to indicate time or clock event between two data patterns of interest. A statistics feature is provided to calculate the number count of a userdefined data pattern that shows up within the overall acquired data stream or to calculate the number count of a user defined high-low status of the data section that shows up in a channel. GLA-1000 Series also offers a tool to perform the analysis of serial bus protocol. This feature supports the most popular standards, RS-232C & I C.
User-friendly Operation
All the settings & operations of GLA-1000 Series are done under the Windows TM environment, which offers the customizable keyboard shortcuts and the toolbar icons that could significantly shorten the learning curve of the first-time users. The horizontal scale of the display is selectable between time and sampling clock and the data waveform is selectable between Ramp & Square to accommodate various application demands. The screen background and data waveforms are all color-definable to ease the observation of display Information. A default color configuration is provided for easy getting-back to the standard color setting once needed.
Flexible File Export Functions
The whole, or a user-defined clip, of screen image, captured data and setting of GLA-1000 Series could be saved as various types of files into PC for further data analysis, reporting, and other applications. The USB 2.0 communication between GLA-1000 Series and the PC guarantees the secured data transfer at the maximum speed while providing GLA-1000 Series with a power source.
