Operating Features

Introduction

This section explains Kinetix

’s

different modes of operation and the best modes to optimize

imaging performance.

Modes and
Gain States

Kinetix has three modes

1.

Dynamic Range

2.

Sensitivity

3.

Speed

The Dynamic Range (16-bit) mode provides the best balance between full-well capacity and

noise performance. However, it provides lower frame rates than the single gain outputs.

The Sensitivity (12-bit) mode provides the lowest read noise performance, achieving
approximately 1.2e- of read noise. The signal is sampled twice by configuring both the

amplifiers to have high sensitivity. CMS modes trades off dynamic range for lower read
noise.

The Speed (8-bit) mode provides the highest frame rates.

Bias Offset
Setting

The factory default bias level is approximately 100 ADU in the Dynamic Range and
Sensitivity modes. The default bias level is approximately 20 ADU in the Speed mode. If
supported by the software application being used, the bias level can be changed. It is
recommended that this value not be changed as the preset values for the defective pixel
noise filters are set with this value.

Clearing Mode
Selection

Kinetix provides a single clear mode

–

“Clear Auto”.

Kinetix is continuously clearing the

sensor while there are no images being acquired. This eliminates unnecessary sensor
clearing and maximizes frame rates.

The following waveforms show how the overlap behavio

r of “Clear Auto” functions for the

Kinetix camera.
