4. Once you have selected the integration time, note the configuration of the pins in the
Jumper Block 4 column of the chart.
5. Remove your spectrometer from its housing. Do not tamper with the optical bench.
(If you have more than one channel in your system, you may have to disconnect the
channels from one another. The master spectrometer is usually on the bottom of a
multiple channel system.) In the center of the green circuit board, near the optical
bench, find Jumper Block 4, labeled JP4. (See the figure to the right.) Jumper
Block 4 consists of the first four pins, which are numbered 1, 2, 3, and 4. Using
jumpers, configure the pins to match the integration time you selected. (See chart
on previous page.)
For example:
"
You have an S2000 and an ADC1000 A/D converter
" Out of your four choices for an integration time, you select 13.3 milliseconds
" Pins 1-2 must be open and Pins 3-4 must be shorted
" Leave Pins 1-2 uncovered and place a jumper over Pins 3-4
6. Set other acquisition parameters such as averaging and boxcar smoothing in the software via the Acquisition
Dialog Bar or the Configure Data Acquisition dialog box. To access the dialog box, click the Data Acquisition
icon or select Spectrum | Configure Data Acquisition from the menu.
7. Select Spectrum | Configure Data Acquisition from the menu. Choose the External Trigger page and select
Hardware Trigger.
8. To save processed data with each external trigger, enable the Automatically save file on trigger box. If you
enable this function, you will be presented with a file save dialog box with each trigger. To avoid manually
naming a file for each trigger, you can enable the Autoincrement Filenames function by selecting File |
Autoincrement Filenames | Enabled from the menu. Choose a base name and starting index for the
autoincremented files.
9. Once you select an external trigger mode, it will appear on your computer that your spectrometer is
unresponsive. Instead, it is waiting for the trigger. Activate your triggering device. The acquisition parameters,
name of the window acquiring data and trigger mode are displayed in the main status bar.
It is important to note that if you apply triggers faster than the fixed integration time, you will miss acquisitions.
