MAESTRO User’s Manual Revision 8.1 84 *SWA Set Personal Wavelength Correction This command is used to specify the wavelength being used on the detector. The EEPROM in the detector contains measured spectral data for a wide range of wavelengths. If the wavelength input by the user is different from the predefined list of wavelengths in the device, a custom value is interpolated. Specifying zero as a wavelength or providing an out-of-bound value as a parameter restores the default settings.
MAESTRO User’s Manual Revision 8.1 85 *TLA Set Trigger Level This command sets the internal trigger level when using the device in energy reading mode. Text Command Parameters Return TLA Trigger Level (percentage) ACK Default: 2% The value should be set between 1 and 100 (floating point values are allowed). In text mode, you may add a “%” symbol after the value for clarity. Example Text Command: *TLA 15.
MAESTRO User’s Manual Revision 8.1 86 *EAA Set Anticipation This command is used to enable or disable the anticipation processing when the device is reading from a wattmeter. The anticipation is a software-reading acceleration algorithm that provides faster readings using the detector’s calibration.
MAESTRO User’s Manual Revision 8.1 87 *HEA This command is used to query the model name of the current head. Text Command Parameters HEA Example Text Command: Return Name of the current heads *HEA Response from MAESTRO QE-25-SP-MB *BAT Query Battery Power This command is used to query the device battery’s remaining power.
MAESTRO User’s Manual 3.4.4.2 Revision 8.1 88 Error Messages for SOLO2 Serial mode # Error Comment 1 Command not found Command is invalid. 2 Invalid Parameter The parameter value is out of valid range, or not of expected type (text, numeric, flag). 3 Not Enough Parameters The expected number of parameters should always be sent. 4 Head is not available Verify that the detector’s DB15 connector is fully engaged with the meter.
MAESTRO User’s Manual Revision 8.1 89 4 MAINTENANCE 4.1 USB installation for the MAESTRO The MAESTRO has a USB type mini B port. When connected to a PC it emulates a standard serial port. This means that it is possible to connect many MAESTROs on one computer, without tying up the ordinary serial ports, while keeping a simple interface that is easy to design software for. The MAESTRO can function using the USB port power only.

MAESTRO User’s Manual 6 6.1 Revision 8.1 91 APPENDIX A QED/12/25/50/65/95 Attenuator/Diffuser Calibration Procedure Introduction; These “Attenuator/Diffusers” must be user calibrated. The calibration procedure is relatively simple. First make measurement without the attenuator, then with the attenuator. The ratio of these measurements will be your correction. This procedure is suitable at any wavelength.
MAESTRO User’s Manual Revision 8.1 92 Step 3: Measure the energy level without the attenuator. To reduce random uncertainty, you should average a number of shots. We recommend at least one hundred shots. This should reduce random errors by a factor of 10. (Square root of “n” assuming Gaussian distribution). Step 4: Install the attenuator. Without changing the laser settings, measure the energy level by averaging the same number of shots.
