The Ekdahl FAR - Configuration utility - Statistics tab
The Statistics-tab
The statistics-tabs main purpose is to relay timed information used for debugging and testing different values and interactions. By checking the Live update-checkbox the information is automatically updated on a continuous basis.
The left hand vertical scale is linearly showing values in between 0-65535 which corresponds to the 16-bit values that most of the Ekdahl FAR commands accept. The right hand scale is a logarithmic scale that is useful for comparing frequency information. The horizontal scale is a linear scale denoting time from software start.
Visibility
The visibility pane on the right hand side allows the user to hide and show graph information.
A0-A7 shows the input to the eight analog-to-digital converters of the Control box.
The Set mot. freq. is the frequency that the bowing wheel is set to rotate at while the Read mot. freq. is the actual frequency read. the PID peak error shows the error in between the wanted frequency and the actual frequency. The Motor current graph shows the current consumption of the bowing motor.
Pickup audio RMS shows the RMS value of the audio as measured by the pickup while the Pickup audio peak shows the peak value. The Pickup FFT freq. shows the fundamental frequency calculated from the pickup audio.
