Technology Cube Enterprise is pleased to announce the release of The System for Acquisition, Analysis and Measurement. S A A M - II 1.1 INTRODUCTION SAAM - II is a modular system for Acquisition, Analysis, and Measurements of transient or repetitive phenomena. Due to extensive modularity, the system can be adapted to a plethora of acquisition situations including slow - speed data acquisition. The software - selectable data acquisition options include : - selection of a variable sampling rate, - triggering threshold levels and - variable number of thresholds - split sampling can also be easily achieved. The system is controlled via the industry - STANDARD IEEE - 488 General Purpose Interface Bus ( GPIB ), allowing ease of expansion. 1.1.2 HARDWARE SAAM - II is composed of three different modules which perform different functions. Depending on the type of data acquisition situation, they can be configured to fulfill a specific purpose. Modules can be easily added and removed as they are in the form of plug - in cards and are available immediately. SAAM - II has the following modules : - The SAAM - PAD module This module consitutes the A/D converter with programmable amplification and onboard memory. The SAAM - PTB module This is the programmable timing module and is the heart - beat of the data acquisition. This module controls the overall timing activity of the system including sampling rate selection, memory splitting in pre - and post - trigger blocks. The SAAM - PTG module This module is used for generation of pulses from a predefined point on the input waveform. This can be used as a trigger signal to the system or can also be used in an external application such as process control. 1.1.3 Software As a system is only as good as its user - friendliness, a lot of effort has been spent in developing a friendly intuitive user interface. The software has been written to allow easy programming of the hardware and is pull down menu driven. A number of validation checks are performed internally and intelligently. The acquired data can be converted into LOTUS spreadsheet format of can be exported to the DaDisp package. Development and implementation of customer specific software for data analysis is also possible and can be incorporated into the system. 1.2 Areas of Applications The SAAM - II system can be used for Data Acquisition from * Accelerometers * Load Cells * Pressure Transducers * Strain Gauges It can also be used in Measurement Systems for * Vibration Testing * Impact Testing * Internal Combustion Engine Testing * Computer Development - for simultaneous signal monitoring over various digital signal lines * RADAR Research * Ballistics Research * Electro - Chemistry * Nuclear Physics 1.3 Salient Features of SAAM - II * Modular Design for maximum application flexibility and ease of maintenance * 12 - bit resolution * Programmable Sampling Rate ( upto 165K samples / second ) * On Board Memory upto 32K samples per channel * Maximum number of A/D channels upto 16 * True simultaneous Sampling on all 16 channels * Programmable Amplification Factor for the input signals in units of 1 - 2 - 5 - 10 - 20 - 50 times the input * Window Triggering Facility allowing generation of trigger signal when input is between or outside two predefined Thresholds * Slope Selection Facility for generation of trigger signal ( positive or negative ) * System functions as one of the GPIB Bus Controlled Instrument * Conversion of the acquired data to Lotus - 123 format for or DaDisp format * Selection of the number of pre-triger and post-trigger samples ( sum being equal to the total onboard memory ) * Software selectable facility of constant addition and multiplication factor ( sample point displayed = actual input * multiplication factor + constant offset ) * Clock pulse initiating each conversion could be external or internal * Trigger source can be from comparator, from external source or from software * Generation of trigger by the comparator could be from 0% to 100% of the range set for the comparator 1.4 SAAM - II System Specifications a.
