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.

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.

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.
