Application description SignalScope Pro for iPhone OS devices is a real-time analysis toolset, suitable for use in areas such as acoustics, audio, electronics, and vibration. SignalScope Pro includes 3 tools for time or frequency domain signal analysis, as well as a signal generator for producing test signals.
SignalScope Pro also turns your iPhone or iPod touch into a platform for data acquisition, storing acquired data in ascii text files, MAT-files, or images for later retrieval from your device.
Input signals can be acquired from the built-in accelerometer, or from the current audio input path (the iPhone OS automatically selects the audio input path according to which external audio devices, if any, are connected to your device). Different engineering units, including Volts, Amps, pascals, g’s, and ips (inches per second) can be assigned to input channels of the dock connector audio input or the headset input (not available on 1st generation iPod touch devices). Sensitivity calibration can also be performed for any audio input device or input channel.
Touch your data with highly interactive, multi-touch enabled analyzer displays.
NOTE: The frequency response of the iPhone’s built-in and headset microphones is quite flat. However, the built-in microphone of the original iPhone seems to be routed through a codec, which limits the sample rate to 8 kHz and significantly affects the frequency response. The iPhone 3G rolls off the built-in and headset mic signals below 100 Hz.
NOTE: First generation iPod touch requires a dock connector audio input device to get audio signals into SignalScope Pro (headphones may also need to be plugged in for this to work).
