PC-connected Instruments
PC computers are everywhere, and are increasingly the system of choice for storing and managing your precious physiometry data. And there is also a dizzying array of powerful data collection systems available, if you have the funds and the time to digest the manual. We try to keep things simple! The UFI devices below include built-in (12 bit) data collection and an isolated USB connector, along with simple PC software. Especially if you do not already have your own data collection system, these devices can simplify your research life!
EZ-IBI Interbeat (R-R) Interval Monitor
Carefully place three standard ECG electrodes on your subject, connect them to this compact, 9V battery-powered module, and you'll be able to measure cardiac interbeat interval (IBI) with millisecond accuracy. Just add a standard USB cable to your PC computer, fire up the EZ-IBI software, and you are on your way. If you are studying human ECG, this is about as simple as it gets!
The EZ-IBI features a low-noise Fetrode™ signal conditioner, built in 12-bit A-to-D data collection with a 1000-Hz ECG sample rate and automatic R-wave detection and R-R interval timing. Then we add an isolated USB link to your PC for enhanced subject safety. Easy-to-use Windows™ software to save, display and print your ECG/IBI data is also included. (The picture above is dated; USB is our standard link!)
SC-2000 Simple Scope™
For ECG and IBI, the EZ-IBI (above) is E Z !!! But what if you want one or more different channels? Respiration? Finger PPG? Temperature? Thats where the Simple Scope comes in!
The SC2000 Simple Scope™ is a compact desktop instrument with a built-in LCD signal display for on-line signal monitoring. Each Simple Scope is custom configured for one, two, sometimes more channels of user-specified input signal conditioning. Thats right! You tell us what channels you want, and we will build your Simple Scope!
Available input channels include bioelectric signals (ECG, EMG, EOG, EEG, EGG) as well as transducer channels such as respiration, force, displacement, pressure, PPG, pulse, temperature and more. We can even include a bioimpedance channel in some cases (Impedance Respiration for example). Gain and frequency response are built to your requirements, and Size controls can often be added as well. And we can include several post-processing algorithms to supply even more physiometry channels (IBI, Respiration Rate, etc.).
Overall, the Simple Scope can be supplied as one of two instruments.
- If you have your own data collection system, the Simple Scope can be configured with (unisolated) Analog, high level outputs (typically BNC) for connection to your data collection system.
- We can also add built-in 12 bit data collection and an isolated USB port for connection to your computer (just like the EZ-IBI). The Simple Scope software generally supplies eight selectable sample rates from 0.5 to 100 Hz.
SRS2004/d Four-Channel Data Recording System
The Model SRS2004/d is a versatile, desk top, four-channel, 12-bit data recording system targetting Student use. Each channel of signal conditioning is patterned after that used in traditional paper chart recorders; both Size and Positon controls are included. Each channel supports a broad selection of measures from the basic bioelectric signals to transducers and more. The four channels are parallel sampled at between 0.5 to 100 Hz. A built-in LCD display makes viewing signal conditioner output easy even before you connect your PC. An isolated USB interface routes the sampled data to PC based "Simple Software" operating on your computer. This program plots either one or all four channels of data. Output data are available in ASCII text format as well, allowing easy analysis by a variety of third-party software packages. Power is supplied by either USB power, a standard 9V battery or wall-mount transformer.
