產品介紹∣資料擷取軟體

Acquire是Signal Recovery專用資料擷取軟體，最近再次進行更新，增加了支援機型7230鎖相放大器及經過測試已可於Windows XP/Vista/Windows 7作業系統電腦上運行。
它採用Signal Recovery SRInstComms ActiveX控制項背後的技術，最多可同時操作Signal Recovery的10台儀器。因此，舉例而言，假如您正在進行阻抗測量，您可讓一台鎖相放大器記錄取樣電流信號，同時，讓第二台記錄取樣電壓。在使用5113前置放大器的實驗中，您可以調整設定，而在Boxcar設定中，您可以透過4161A雙通道ADC記錄4121B Boxcar信號平均器的輸出。假如您沒有4161A，你甚至可以使用一台鎖相放大器的輔助輸入及輸出來運行boxcar實驗。
軟體包含一個功能強大的繪圖引擎，可使用各種線條樣式依需求顯示資料、可將資料匯出為txt與CSV格式檔案、提供全面的剪貼簿支援，並包含一個依畫面內容提示說明的輔助系統。
軟體也簡化了與硬體的連接程序 - 無須調整儀器上的通訊設定，只須透過乙太網路、USB、GPIB或RS232串列埠（依儀器與電腦上可使用的連接埠而定）連接及讓軟體找到硬體即可。每次當您啟動應用程式時，它會檢查需要的儀器是否已經連接，假如沒有，會提供警示訊息給您。
此程式提供二種主要操作模式：虛擬前面板（Virtual Front Panel）及實驗記錄模式（Experiment Recording Mode），說明如下：
- 虛擬前面板模式（Virtual Front Panel）：
  - 在此模式下，幾乎連接的儀器的所有功能，都可透過一個“遠端前面板” 屬性工作表上的系列屬性頁面，從電腦進行控制。每張工作表都反映了受控制儀器所提供的功能。
  - 儀器的2個資料輸出，可從提供的範圍選擇，而這些都清楚地顯示在螢幕畫面上。
  - 假如連接了多台儀器，可以打開每台儀器的獨立面板。在經過正確設定後，可以使用一個按鈕收縮這些面板，以節省螢幕空間，而只顯示輸出。
- 實驗記錄模式（Experiment Recording Mode）：
  - 在此模式下，實驗的定義，是將儀器輸出記錄為某X軸變數的函數。
  - X軸變數的可能範圍，取決於所連接儀器的性能，但包括一些參數例如：時間、頻率、振盪器振幅、輔助DAC電壓、數位延遲及觸發事件等。
  - 資料是在擷取時或擷取後依使用者定義的軸線被繪製顯示在螢幕上。然後，在將畫面列印輸出到任何Windows相容的印表機或繪圖機前，可以將它先調整為需要的形式。
  - 資料也可匯出成ASCII或CSV（逗號分隔值）文字檔案，以便使用第三方軟體進一步分析。
  - 程式可將定義的實驗儲存為“測試”檔案，以便輕鬆複製先前運行的實驗。
  - 實驗定義也一併儲存在保存的資料檔案中，可以從資料檔案中讀出及重新載入。
  - 假如須要重複運行相同的實驗，可以在退出程式時先儲存這些設定，再於啟動時重新載入，以得到更大的便利。
支援曲線緩衝區及快速緩衝區/暫態記錄器模式：
- 機型7225、7265及7280包括32,768點曲線緩衝區，而機型7124、7230及7270則有100,000點。Acquire程式完全支援這些曲線緩衝區，包括使用二進製曲線轉儲，以加速資料傳輸。
- 使用緩衝區，可進行比資料擷取時將資料顯示到螢幕上更快速的資料擷取，而程式如今也可進行使用緩衝模式的頻率掃描。
- 暫態記錄器模式，可在機型7225、7265及7280中，以40kSa/s（每點25μs）的速率，將任何±10V類比波形數位化為16位元；而在機型7124、7230及7270中，更可以高達250kSa/s（每點4μs）的速率操作，無需額外成本，即可提供有用的額外功能。

Acquire適用於Signal Recovery幾乎所有電腦控制儀器，並且透過RS232、GPIB（IEEE-488）、乙太網路、直接USB或USB（經由型號CE0115S或CE0116S）介面操作。
最多可同時操作10台以下列出的機型儀器：5105、5106、5110（A）、5209、5210、7124、7220、7220BFP、7225、7225BFP、7230、7260、7265、7270、7280、7280BFP、7310、4161A、9650A（搭配9650A /97 GPIB選購）及5113。
需要的電腦規格：運行速度1.0GHz或更快、具備硬碟、光碟機、2MB可用磁碟空間、適用的通訊埠（乙太網路、RS232、USB或一個閒置的內部PCI匯流排插槽）及Microsoft Windows XP/Vista/Windows 7或更新版本作業系統，以便進行完整安裝及操作。
包括一個全面性依畫面內容提示說明的輔助系統，註冊使用者可獲得免費支援。
訂購時，會提供軟體光碟及83頁印刷版操作手冊資料。

"Acquire" is the name of our dedicated data acquisition software, recently again updated to add support for the model 7230 lock-in amplifier as well as being tested to run on PC's using Windows XP, Vista, and Windows 7 operating systems. It uses the technology behind our SRInstComms ActiveX control to allow you to operate up to ten of our instruments simultaneously. Hence, for example, if you are making impedance measurements you cause one lock-in amplifier to record the sample current signal while a second logs the sample voltage. In experiments using our 5113 preamplifier you can adjust the settings, while in boxcar setups you can record the output of a 4121B Boxcar Averager via a 4161A Dual Channel ADC. And if you don't have a 4161A, you can even use the auxiliary inputs and outputs on a lock-it to run a boxcar experiment.
The software includes a powerful plotting engine that lets you show data just as you want it using a variety of line styles, allows data export to both text and CSV files, offers comprehensive clipboard support, and includes a context-sensitive help system.
The software also makes connecting up hardware as easy as possible. There is no need to adjust communications settings on the instrument - simply connect it up via Ethernet, USB, GPIB, or RS232 serial (depending on the ports available on the instrument and on the PC) and let the software find it.
Each time you start the application it checks that the required instruments are connected and warns you if they are not.
The program offers two main operating modes, Virtual Front Panel and Experiment Recording Mode, as follows:
- Virtual Front Panel:
  - In this mode virtually all of the functions of the connected instrument(s) can be controlled from the computer via series of property pages on a "remote front panel" property sheet.
  - Each sheet reflects the features available in the controlled instrument.
  - Two data outputs from the instrument can be selected from the range available and these are clearly shown on-screen.
  - If several instruments are connected then separate panels can be opened for each one.
  - Once correctly set up, a button allows the panels to be shrunk to conserve screen space so that only the outputs are displayed.
- Experiment Recording Mode:
  - In this mode an experiment is defined in which the instrument output(s) are recorded as a function of some X-axis variable.
  - The range of possibilities for the X-axis variable depends on the capabilities of the connected instruments, but include such parameters as time, frequency, oscillator amplitude, auxiliary DAC voltage, digital delay and trigger events.
  - Data is plotted to screen either as it is acquired or after acquisition on user-defined axes. You can then adjust the display to the required form prior to generating hard-copy output on any Windows compatible printer or plotter.
  - Data may also be exported to ASCII or CSV (comma separated value) text files for further analysis with third party software.
  - The program includes the ability to save defined experiments as "test" files allowing easy replication of previous runs.
  - Experiment definitions are also stored within saved data files, and can be extracted and reloaded from them.
  - If you need to run the same experiment repeatedly then settings can be saved on program exit and reloaded on startup for greater convenience.
Support for Curve Buffer and Fast Buffer/Transient Recorder Modes:
- The models 7225, 7265 and 7280 include 32,768 point curve buffers, while those in the models 7124, 7230, and 7270 have 100,000 points. Acquire fully supports these, including the use of binary curve dumps to speed data transfer.
- Use of the buffer allows much faster data acquisition than is possible when data is displayed to screen as it is being taken, while the program now also allows frequency sweeps using the buffered mode.
- Transient recorder mode will digitize any ±10V analog waveform to 16 bits at 40kSa/s (25µs per point) in the 7225, 7265 and 7280, while in the 7124, 7230, and 7270 it can operate at rates up to 250kSa/s (4µs per point), giving a useful extra feature at no extra cost.

Acquire is suitable for use with virtually all our computer-controlled instruments and operates via either the RS232, GPIB (IEEE-488), Ethernet, Direct USB, or USB (via models CE0115S or CE0116S) interfaces.
Up to ten instruments from the following list can be operated simultaneously: 5105, 5106, 5110(A), 5209, 5210, 7124, 7220, 7220BFP, 7225, 7225BFP, 7230, 7260, 7265, 7270, 7280, 7280BFP, 7310, 4161A, 9650A (with 9650A/97 GPIB option) and 5113.
It requires a PC computer running at 1.0GHz or faster with hard disk, CD, 2 MByte of free disk space, suitable communications ports (either Ethernet, RS232, USB or a free internal PCI bus slot), and Microsoft Windows XP/Vista/Windows 7 or later for full installation and operation.
It includes a comprehensive context-sensitive help system and free support is available to registered users.
If ordered through our normal distribution channels it is supplied on a CD complete with 83-page printed instruction manual.
