System Installation 4 System Installation Step 1: Photon II Driver Installation Instructions The Photon II communicates with the PC through a USB connection. This requires Windows driver software to enable the USB connection. The USB is a “plug and play” device which means that after the driver is initially installed, the configuration of the driver is automatically launched every time the device is plugged into the USB port.

Once this calibration data is stored, the input measurement and the signal source can be adjusted back to the most accurate value. The LDS-Dactron system uses sigma-delta A/D and D/A converters and an anti-aliasing filter with a very high cutoff frequency. As a result, the amplitude characteristics of the input and output are not frequency dependent.
0.25%. The AC bandwidth for the voltmeter should be higher than 10 kHz. The voltmeter accuracy should be 0.25% or better in order to ensure that the LDS-Dactron system is calibrated to an accuracy of ±1% (about ±0.1dB). Generally, the calibration meter’s Photon II System Guide...

Calibration Connect Cables with Photon II and Start Software Cable Connection for Calibration Connect the BNC cables to all input channels and the OUTPUT channel at one end. Connect all the other ends together with BNC T ports. Connect this cable harness to a voltmeter that is certified to the accuracy standard described above (0.25%).
Page 34
Calibration Select after the appropriate information has been entered. This will open the normal Calibration screen and dialog informing you to allow the Front-End DSP Box to warm up for at least 10 minutes; click on OK to access the Calibration screen. Before pressing the button, Start measure the DC voltage offset on the OUTPUT channel.
Page 35
Calibration DC Measurement for Offset Calibration You will also be requested to measure the RMS value of the output at the AC 10 Volt full-scale range and type it into the dialog box. Please make sure that the voltmeter is switched to AC measurement. This concludes the calibration of the OUTPUT channel.
Page 36
Calibration Input Channel Calibration The input channels are calibrated automatically. The system will now use the calibrated OUTPUT channel as the signal source. The gain error and offset estimation are calculated automatically for all the input range settings. The input calibration process depends on an accurately calibrated OUTPUT channel.
Page 37
Calibration AC Measurement for the Gain Validation After validation, both the offset and gain error should be within tolerance. The pass/no-pass tolerance used during the validation is: 10 volt range: 1% of the Full Scale 1.0 volt range: 2% of the Full Scale Low-voltage Range Calibration The Photon II has low voltage input ranges of 0.1 V and 0.01 V.
Page 38
Calibration … Cable Connection for Low-voltage Range Calibration The dialog boxes below ask for a measurement and entry of the DC and AC reading from the meter. These measurements will be used for the Output Channel calibration so that the low voltage Input Channel calibration is provided with an accurately calibrated signal source.

System Troubleshooting 7 System Troubleshooting The diagram below shows the structured layers of the LDS-Dactron Photon II System. Each layer generates and sends a message to the system user interface in the event of an error condition. These messages aid in diagnosing and resolving problems.
System Troubleshooting Follow the instructions provided to re-establish communication with the Photon II. Selecting “Ignore” will initialize RT Pro Playback, for offline data analysis. Check if USB driver is installed correctly To determine if the driver software has been installed and if the PC recognizes the Photon II, first connect the Photon II to the PC with a USB cable.

“LDS-Dactron Photon (USB) device” in the list as shown below. The LDS-Dactron Photon USB device driver will only be listed if the Photon II hardware is connected to the PC via the USB cable. If the Photon II is not connected it will not be listed in the Device Manager list.
System Troubleshooting If the LDS-Dactron Photon USB device driver is not listed and the Photon II is plugged in then the driver may not be installed correctly. In this case, try to reinstall, or update, the device driver. This may also be a symptom that the PC USB port does not supply adequate voltage to the Photon II.
• The SYS led flashes then becomes dim or goes dark when the Photon II is connected to the PC with a USB cable. • The LDS-Dactron Photon (USB) device Driver was installed and the Photon II is connected to the PC by a USB device, but the driver is not listed on the Device Manager list under the System Control Panel.
