qt_burst_lengths[] |
uint8_t |
The burst length for each of the QMatrix channel in units of pulses. Default value: 64 pulses. These values can be configured for each channel individually. |
The signal gain for each sensor is controlled by circuit parameters as well as the burst length. The burst length is simply the number of times the charge-transfer (‘QT’) process is performed on a given sensor. Each QT process is simply the pulsing of an X line once, with a corresponding Y line enabled to capture the resulting charge passed through the sensor’s capacitance Cx.
The QMatrix acquisition method library exports a variable of this type which can be accessed to set the burst length for each of the QMatrix channels
