|Resolution and Noise
The high resolution of the iWorx 300 series recorders combined with an unparalleled signal-to-noise ratio (noise as low as 32 microvolts) make it possible to resolve even the most subtle changes in pressure, tension, temperature, or other research parameters. For example, in vascular tissue studies, tension as low as 1 mg can be measured reliably. Likewise, changes as low as 0.1° C during thermal studies, or pressure changes as low as 0.1 mmHg during vascular studies, can easily be resolved.
Each channel of the iWorx 300 series recorders is equipped with an independently programmable 16 bit, +/-10V stimulator (DAC). Parameters for each stimulator, such as pulse width, frequency and amplitude, may be changed “on-the-fly” using handy controls located in the LabScribe2™ software tool bar. Standard protocols include Pulse, Train, Step, Triangle and Ramp. Each standard protocol allows the quiescent state to be a holding voltage, thereby making it ideal for voltage clamping applications.
Eight digital outputs are available to control devices such as pumps and valves. Programming the output lines is point-and-click easy, with no complicated scripting language required.
These recorders have a maximum sampling speed of 5 kHz on each channel, more than fast enough for the applications for which they are intended.
