14.4.3 Scanning a Predefined Wavelength/Frequency Range
Subject
The
Scan
function enables you to scan a predefined wavelength range step-by-step,
using the channel increment defined in the
Step
sub-menu to directly set the emission
wavelength (or optical frequency) of the TLS-50 tunable laser.
Starting from the first wavelength (the lower wavelength limit you have set), the emission
wavelength increases incrementally (the wavelength increment is stored in the
Step
parameter) up to the last wavelength value (the upper wavelength limit you have set).
During each scan interval, the OSICS TLS-50 module scans at a selected wavelength
range for the duration specified by the
Delay
parameter.
14.4.3.1 Setting the Scan Parameters
Subject
This section explains how to configure the scan mode by setting the following
parameters:
•
The first and last channel of the scan
•
The value of the channel step that is used in the scan
•
The time between steps
•
The number of cycles of the scan
The laser stabilization is in the millisecond range. You can immediately use it for accurate
measurements.
Procedure
1.
Access the TLS-50
Unit Setup
menu (see section
Accessing an OSICS Module Setup
).
2.
Expand the
Scan
menu and enter the wanted setting menus:
•
Start
Channel
sub-menu: to select the first channelof the scan.
•
End
Channel
sub-menu: to select the last channelof the scan.
•
Step
sub-menu: to select the value of the channelstep that you want to use for
the scan.
•
Delay
sub-menu: to select the duration of a scan step.
•
Scan
Number
sub-menu: to select the number of scan cycles. If you select 0000,
the OSICS TLS-50 will scan indefinitely.
The sub-menu appears and displays the value of the corresponding scan parameter.
3.
Modify the value as follows:
a. Turn the rotary knob to put the cursor under the digit you want to modify and
press the knob to highlight it.
b. Turn the knob clockwise to increase the value or anticlockwise to decrease it and
press the knob to validate the selected digit.
c. Perform steps a. and b. again with the other digits to modify.
d. Turn the rotary knob clockwise to put the cursor under
ENTER
and press the
knob to validate the new value.
The TLS-50
Unit Setup
menu is automatically displayed and the scan parameters are
set.
14.4.3.2 Controlling the Scan
Subject
This section explains how to start, stop and resume the scan.
