UFI Model 1504 Series Signal Simulators
The UFI Model 1504 Signal Simulator line provides a wide range of input test signals to allow quick, reliable checks of your bioresearch measurement equipment. Models 1504-SCL and 1504-SP-HF are designed specifically for testing our Model 3991 Hot Flash Monitor BioLogs™ or other SCL/HF recording systems.
Model 1504
The standard Model 1504 provides a single channel of a standardized waveform -- a low-amplitude, low-frequency differential square wave -- that is adequate for testing most signal conditioners.
Model 1504 specifications
- Number of output channels: one
- Output signal type: square wave
- Output signal frequencies: 0.8, 7.5, 15, and 30 Hz
- Output signal levels: 25, 50, 100, 500 and 1000 microvolts
- Output signal configuration: differential (plus, reference and minus)
- Output impedance: 100 ohms
- Output connectors: three standard male snaps
- Power supply: 9V battery
- Size: 5.5" x 3.25" x 1.5" (140mm x 83mm x 38mm)
- Weight: 8 ounces (227g)
Models 1504SP and 1504SPG
The Model 1504SP custom signal simulator provides one to three channels of user-specified signal waveforms at user-specified levels. The 1504SP shown apove provides simulation for both SCL and PPG. The 1504SPG (not pictured) includes an LCD waveform display to allow a convenient check on the waveform at the simulator so you know what to expect from the equipment under test.
Model 1504SP(G) specifications
- Number of output channels: one to three
- Output signal waveform: per customer requirements -- sine, square, triangle, sawtooth waves; or synthesized (ECG, IBI calibration chain, etc)
- Output signal frequencies: 0.001 to 500 Hz
- Output signal type: voltage or impedance change
- Output signal configuration: single-ended (plus, minus) or differential (plus, reference and minus)
- Output connector(s): per customer requirements
- Waveform display (SPG only): 64 x 128 pixel LCD
- Power supply: 9V battery or wall-mount transformer
- Size: 7" x 5" x 2.5" (178mm x 127mm x 64mm)
- Weight: 16 ounces typical (454g)
Signal Simulators for SCL and Hot Flash Monitoring
Model 1504-SCL standard SCL simulator
The Model 1504-SCL supplies a switch-selectable simulation of skin conductances of 0, 10, 20 and 30 micromhos (microsiemens). Built-in switches can add an additional 0.1 or 1.0 micromhos to test transient response.
Model 1504SP-HF Hot Flash simulator
The Model 1504SP-HF delivers an authentic spike in skin conductance to simulate the actual hot flash phenomenon. After the user programs a "baseline" skin conductance, this unit periodically imposes an adjustable hot flash contour on the baseline value. Hot flash magnitude and repetition interval are set with front-panel switches.
