Chapter 6 WinSpec/32 and WinView/32 First Light Procedure 51
• Acquire
Acquire is typically used for the collection and storage of data. In Acquire mode,
every frame of data collected can be automatically stored, so the completed dataset
may include multiple frames with one or more set of accumulations. This mode is
typically selected during actual data collection.
One limitation of Acquire mode when operating in Fast Mode is that if data
acquisition continues at too fast a rate for it to be stored, data overflow may occur.
REFERENCES:
For information about synchronizing data acquisition with
external devices, refer to
Chapter 8, Experiment
Synchronization , on page 71.
All procedures in this chapter assume:
•
The NIRvana-LN system has been installed and setup in accordance with the
instructions in previous chapters.
•
WinX/32 has been previously installed on the host computer.
•
Familiarity with WinX/32.
If this is not the case, review the WinSpec/32 User’s Manual (refer to
Table 1-1 ,
Related Documentation , on page 9,) or have it available while performing this
procedure.
•
Section 4.10, Fill the Dewar , on page 37, has been read prior to filling the Dewar;
•
The system is being operated in spectroscopy mode.
•
The spectrograph has an entrance slit shutter that is being controlled by the
NIRvana-LN via the
Shutter
connector.
6.2 Power On Sequencing
The NIRvana-LN camera must be powered on before WinX/32 is launched in order to
establish and maintain communication between the NIRvana-LN camera and the host
computer.
If WinX/32 is launched before the NIRvana-LN has been powered on, many of the
functions will be disabled. Only previously saved data can be retrieved and/or examined.
6.3 System Setup and Configuration
Perform the following procedure to set up the system hardware:
1. Set the spectrograph entrance slit width to to 25 µm.
2.
Mount a light source in front of the entrance slit.
3.
Mount the NIRvana-LN detector to the spectrograph exit port.
