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。
"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.
