Product Feature 產(chǎn)品特點

Simplified User Interface 簡化的用戶界面

The SignalCalc 900 Series user interface simplifies test setup and run time operations. Enter test profile and the configuration wizard automatically sets up associated control and measurement parameters. Import shaker parameters from a large database of standard models to verify test feasibility. All setup, project, test article, and customer information is saved along with measurement data in a database. Easily search for data from different test runs and test types for analysis and report generation.

SignalCalc 900系列軟件用戶界面簡化了參數(shù)設(shè)置和運(yùn)行操作。進(jìn)入測試參數(shù)設(shè)置文件，設(shè)置向?qū)ё詣优渲孟嚓P(guān)的控制和測量參數(shù)。從標(biāo)準(zhǔn)振動臺設(shè)備數(shù)據(jù)庫中導(dǎo)入振動臺參數(shù)，以驗證測試的可行性。所有的設(shè)置、項目、測試文件和客戶信息都存儲在一個數(shù)據(jù)庫文件中，可以輕松地從不同的測試文件和測試類型中搜索數(shù)據(jù)，方便后期分析和報告生成。

Enhanced Signal Analysis Tools 增強(qiáng)型信號分析工具

The SignalCalc 900 Series has a unique ability to add signal analysis measurements to a vibration control test. For example, narrowbａnd FFT, third octave, and histogram measurements can run simultaneously with the vibration control test. These measurements are configured using independent sample rates, bandwidths, block sizes, etc. Independent acquisition, analysis and control systems are no longer required. Signal analysis measurements are immediately available, removing the delay of waiting for post processing of recorded data.

SignalCalc 900系列軟件具有的能力，可以將信號分析功能添加到振動控制測試中。例如，窄帶FFT分析、倍頻程分析和直方圖分析等可以與振動控制測試同時運(yùn)行，這些測量分析是使用獨立的采樣率、帶寬、數(shù)據(jù)塊大小。不再需要兩套獨立的采集、分析和控制系統(tǒng)。信號分析測量瞬間啟動，消除了等待記錄數(shù)據(jù)的時間延遲。

User-Defined Real Time Signal Processing 用戶自定義實時信號處理

SignalCalc 900 Series signal processing tools set includes user-defined custom signal processing. These algorithms are processed during the test in real-time using the embedded digital signal processors in the 901 hardware. The results of these algorithms may be displayed during the test and saved with test data.

SignalCalc 900系列信號處理工具包括用戶自定義信號處理函數(shù)。這些函數(shù)算法在測試過程中使用了901嵌入式數(shù)字信號處理器硬件進(jìn)行實時計算。計算的結(jié)果可以在測試期間顯示，并保存在測試數(shù)據(jù)中。
