UFI SC-2000 Simple Scope™
The SC2000 Simple Scope™ is a compact, battery-operated instrument containing either one or two channels of user-specified input signal conditioning. Built-in A-to-D capability and a graphics LCD display provide a direct indication of input activity without the need for an attached PC. However, signal conditioner outputs for use with another instrument or a PC (running LabView™ etc.) can be be supplied on the back panel of the SC-2000 through BNC connectors. Two more outputs can also be added, giving online calculations of Rate or Interval in addition to digital-to-analog (D-to-A) capability.
If a serial port is added (isolation is an option), the Simple Scope can function as an A-D converter. In this mode, the Simple Scope samples the analog input channel data, digitizes it, and then sends it on to a PC. The PC runs UFI's SIMPLE software allowing the Simple Scope data to be displayed and recorded.
General features of the Simple Scope
- A wide selection of bioelectric input channels is possible, including ECG, EMG, EGG, EEG, and EOG
- Fetrodes™ may used for all bioelectric channels
- Many other transducer channels are available, including respiration, force, displacement, pressure, PPG, pulse, and temperature
- Input connectors are rugged, keyed and locking
- Eight selectable sample rates, between 0.5 and 100 Hz, are typical
- A front-panel signal size control is provided for each channel
- All Simple Scopes are provided with an LCD graphics waveform display
- Controls include an adjustable scan rate with "freeze" feature
- Gain and frequency response are built to your requirements
- On-line peak detection and rate/interval display are other common features
- SIMPLE data collection and display software supports data review, printing and saving to disk or clipboard
- A wide range of post-processing is available for stand- alone display and/or output to another instrument or a PC. Processing options include: interbeat interval for (ECG); event-by-event rate calculation; and PPG magnitude calculation
- BNC output connectors will be provided if required
- On-board 12-bit A-to-D with an isolated USB output port is an option
- Power is supplied by a 9V battery or a wall-mount transformer
- Typical dimensions of the rugged plastic case are 3.5" x 5" x 7" (90mm x 125mm x 180mm); typical weight is 20 ounces (565 grams)
A sampling of available Simple Scopes
The following are just a few of instruments that UFI has built to order for our customers.
Simple Scope SC2000/2-ZR (pictured above)
In this model, UFI's proprietary impedance respiration signal conditioner supplies both ECG and respiration signals from the same two electrodes, supplemented with a reference electrode. ECG and respiration are available as outputs on the back panel. Peaks in the ECG signal are detected, and rate calculations are performed and displayed. Zero crossings by the respiration signal are identified to derive the respiration rate, which is displayed on the LCD. Both the ECG and the respiration rates are converted to scaled voltages that represent the two rates; BNC connectors on the back panel provide these to downstream instruments or to a PC.
Simple Scope SC2000/2-IBI
This Simple Scope features two channels of signal conditioning: one ECG channel using our Fetrodes, and one respiration channel using the UFI Model 1132 Pneumotrace™ respiration transducer. The ECG signal is sampled at 1 KHz and then and peak-detected to calculate the interbeat interval (IBI) in milliseconds. IBI is displayed on the SC2000 LCD; ECG, respiration and IBI are sent via an isolated port to a PC running SIMPLE Software (included).
Simple Scope SC2000/2-EOG
This Simple Scope provides two channels of electro-oculogram (EOG) signal conditioning, using Fetrode input assemblies. Both EOG channels feature microprocessor-based automatic recentering, giving DC response, and both channels are displayed on the LCD. An isolated outputd port supplies the 12-bit EOG data to the customer's PC. Simple PC-based software completes the system.
Model 2701-SC
What do you get when you combine the UFI Simple Scope physiological data recording platform with the Model 2701 skin conductance meter? You get the Model 2701-SC.
