Feature
Meaning
Hardware Trigger
The spectrometer uses an external rising edge of a TTL signal to begin a
single integration cycle. Set the delay (counts) on this screen.
Internal Trigger
Use this tab to select the trigger source and the Trigger period. See your
spectrometer’s manual and the External Triggering document for more
information on triggering for your spectrometer model.
I2C
The Inter-Integrated Circuit 2-wire serial bus is widely used in embedded
systems applications. With I²C you can add peripherals to your system
without using valuable resources like I/O ports. The I2C bus
communications parameters are set on this screen.
Indy
This tab appears for Jaz systems containing the Industrial (Indy) module.
See the Jaz Installation and Operation manual for more information on
JAZ-INDY.
Irradiance
Use this screen to load and save irradiance calibration factors.
LS-450
This tab appears if a USB-LS-450 light source is attached to your
spectrometer. Check the box for Pulsed LED mode, if desired.
LS-450 Calibration
Constants
This tab appears if a USB-LS-450 light source is attached to your
spectrometer.
LS-450 Current Out
This tab appears if a USB-LS-450 light source is attached to your
spectrometer. Adjust the analog output current.
Multi Channel Provider
This screen appears for an ADC1000.
Single Strobe
The Single Strobe signal is a programmable TTL pulse that occurs at a
user determined time during each integration period. Set the counts for
the high and low transition delay.
NOTE:
The High Transition Delay must
always be lower than the Low Transition Delay.
SPI
The Serial Peripheral Interface is a 3-wire interface that can be used to
communicate to multiple slave devices. Access the SPI bus
communications functions on this screen.
Stray Light
Enter the stray light correction coefficient in this screen.
TEC
For QE65000 spectrometers, set the parameters for the TE cooled CCD
array on this screen.
Thermoelectric
For NIR spectrometers.
Trigger Delay
Same as External Trigger Delay.
UV/VIS
ISS-UV-VIS Enable visible lamp, set visible lamp intensity, enable UV
lamp, set UV lamp intensity
