6.1.1. Analog / Digital Gain Settings
ARTCAM-990SWIR is compatible with analog and digital gain.
Setting value of gain on software can be set from 0 ~ 420, and the gain will change from 0.0dB ~
42.0dB accordingly. Gain can be calculated by the following formula:
Gain[dB] = value / 10.0[dB]
Digital gain will activate when setting value of gain > 180.
The graph below shows the relationship between setting value of gain and its magnification[dB].

7. System Requirements
7.1. Recommended System Requirements
●Host Controller
This camera is applicable to USB 3.0.
Connecting to USB 2.0 host controller may cause low-speed or failure to function properly.
●CPU
The driver of this camera is applicable to computer architecture “x86” or “amd64”.
The specification of CPU effects directly the imaging process speed, therefore it is highly
recommended to utilize a high-end CPU if possible.
●Memory
In the viewer software, there is a data buffer which can store 4 to 8 frames.
Therefore, it is necessary to keep spare space at least for 8 frames in the memory.
(For example, when using 1.3MP color camera, 1280 x 1024 x 3 x 8 [byte] = 30[MB] is
necessary.)
It is highly recommended to keep enough memory space especially when using high
resolution camera.
●OS
This camera is applicable only to the architecture of Windows NT (32bit/64bit).
Standard functions are confirmed with OS after Windows.
In addition, it is recommended to use Windows 10.
Caution
■Please refer the restrictions below when you use ARTCAM series.
(1) Recommended System Requirements
If the system specifications do not meet the requirements recommended above, it may be
difficult to run at the maximum frame rate.
(2) Use of other USB3.0 Hardware
The data on our camera/converter is transferred in bulk mode. For this reason, when
using our camera/converter, please avoid using other bulk transferred USB3.0 hardware
such as Memory stick, External HDD, External DVD, CDROM etc.
As a solution, we recommend installing a PCI USB host card to the PC and connect
external USB hardware to this port only.
(3) USB3.0 Cable Extension
We cannot guarantee the functionality of the USB3.0 camera if the user adopts USB3.0
extension cables or repeaters which are not confirmed by us. With the extension cables or
repeaters, the bandwidth of transfer may differ, and thus caused malfunctions such as a
low frame rate or recognition failure on the camera.
What may cause the problem is that the regulation of the power lines becomes not
enough, and so causes impudence mismatch on data signals.
*For the recommended extension cable, please contact our sales department.
