Quantum Data Generator Control Setup
Before attempting to connect Calman to one of the Quantum Data generators listed above, check the following Preference setting on the generator.
- On the Main menu, select Preferences.
- On the Preferences menu, select USB Mode.
- The USB mode options are COM and Disk; select the COM mode to enable Calman communication.
Calman Device Connection Procedure
- If you haven’t already done so, install the device driver for the generator.
- Connect the Quantum Data generator to the computer with a USB cable.
- On the Calman Source Settings tab, click Find Source
- On the Find Source dialog, under Manufacturer, select Quantum Data
- Select the Model to match your Quantum Data generator.
- Select the Com Port or enter the IP address for the connected generator. The generator Com Port can be determined in Windows Device Manager.
- Click Connect on the Find Source dialog.
Calman Source Settings Tab
The Calman Source Settings tab provides Source Information and Settings for the connected Quantum Data Video Generator.
Select the desired test pattern size and type from the Window Size selection box.
Note: For plasma and CRT displays, Constant APL 50 works well.
Calman provides a default measurement delay time of 2 seconds to accommodate the test pattern settling time of the Quantum Data generator and an attached display. To optimize the delay time for a particular configuration, potentially speeding up all measurement times, click the Optimize button.
The Quantum Data 780C has an HD-SDI output that can be controlled by selecting this option. The HD-SDI Colorspace options are BT.601, BT.709, and BT.2020.
The pattern selection field allows you to select patterns from the Quantum Data generator other than the automated measurement windows or fields.
The Quantum Data generators, with firmware version 15092260 or later, can output HDR10 test patterns to enable the HDR10 mode on compatible HDR displays.
- HDR10: The HDR10 option enables a generator’s HDR10 output mode.
Note: The following HDR10 Metadata is the Content Metadata that specifies the specifications of the HDR Mastering Display that was used to create the HDR10 content. To change the default values for the following fields, refer to EIA-861.3. If you do not know what values to set, leave the fields at their default values.
- Mastering Display EOTF: Electrical-Optical Transfer Function. The target luminance response function.
- Mastering Display Primaries: Defines the Mastering Display’s color gamut.
- Mastering Display White Point: The white point of the Mastering Display.
- Mastering Display Max Luminance: The Mastering display’s specified maximum luminance in nits (cd/m2.
- Mastering Display Min Luminance: The Mastering display’s specified minimum luminance in nits (cd/m2).
- MaxCLL: Maximum Content Light Level. The maximum pixel value within the applied content.
- MaxFALL: Maximum Frame-Average Light Level. The maximum value of the frame-averaged maxRGB, over all frames in the content.
