QUAD-4Track User’s Manual Revision 2.1 21
The Sensor Data Display has Controls and Indicators related to the sensor. The sensor
information is read from the sensor memory on program startup.
Controls
The Controls are:
Trigger Source
Trigger Polarity
Log Data
Wavelength (nm)
Analog Out Source
Trigger Source
Selects the Trigger Source, External or Internal. If External is selected, a trigger source must be
connected to the External Trigger BNC.
Trigger Polarity
Selects the External Trigger Polarity, Positive (rising) or Negative (falling) edge.
Log Data
Log data to selected file. if no file is currently open, a prompt will request the file to log
data to. Data files can be opened and closed via the File menu.
Wavelength (nm)
Sets the wavelength of the laser in use.
Since the sensor responsivity varies with wavelength, turning Wavelength Compensation
on with the wavelength set to any value other than the calibration wavelength may cause
a rescale of the available ranges. If this occurs, the instrument will set itself to the same
currently set range if it is still available. If it is not, the instrument will set itself to the
next available range.
Analog Out Source
Selects what is sent to the Analog Out BNC of the QUAD-4TRACK. The Analog Output
provides an amplified, buffered signal from the probe. A Full Scale Reading will
correspond to a 1.5V Signal at the analog out when set to a channel.
The 5th choice is a Bar Graph representing each of the 4 channels. A value of 2.000V is a
full scale representation. Each bar in the graph is approximately 50us wide.
