8.2 Output Signals
8.2.1 Available TTL Output Signals
A 7.2 kHz TTL modulation signal is provided on the following BNC connectors (see
section Description of the Rear Panel, p. 18 ):
• Mod Out : internal modulation signal
• Mod Sync : synchronization signal
8.2.2 Monitoring Outputs
Output connectors located on the rear panel enable continuous monitoring of:
• Actual values of current ( I output),
• Actual values of power ( P output),
• Actual values of wavelength ( λ output)
• Detection of motor displacement ( Sync. output).
These monitor outputs use BNC connectors.
Signal levels are as follows:

8.2.3 Activating/Deactivating the λ Output as a Trigger
Subject You can switch the λ output to a trigger (TTL) that is high when the TUNICS T100S-HP is
scanning (only in positive direction ignoring return and backlash).
Procedure 1. Press the 2nd + 3 keys.
The DATA area display prompts you to activate the BNC connector as a trigger.
2. Press 1 to activate the λ BNC connector as trigger.
3. Press Enter to validate.
You can now use the λ BNC connector as a trigger.
4. To switch the λ BNC connector back as the wavelength output:
a. Press the 2nd + 3 keys
b. Press 0 to deactivate the λ BNC connector as trigger.
c. Press Enter to validate.
