8.5.6 Using the DFB Module as a Modulation Source for External
Devices (OUT 2 Output)
Subject The OSICS Mainframe rear panel (see Figure 2, p. 18 ) features eight channel ports, each
dedicated to a specific channel-slot and identified by its channel number (CH1 to CH8).
As they are numbered from left to right, channel ports do not face across their
corresponding slots.
Each channel can produce two types of output signals on BNC connectors:
• OUT 1 : analog signal for constant monitoring of the laser diode current, output
power or laser chip temperature. For more details, see section Monitoring the OSICS
DFB Module Parameters Using the Analog OUT 1 Output, p. 91 .
• OUT 2 : analog signal from the DFB module (see Figure 41, p. 74 ) that you can use as
an external modulation source for other devices. The following procedure explains
how to set the OUT 2 analog signal.
You can also use the OSICS Mainframe as a modulation source for external devices with
the Synchro BNC output connector, as explained in section Using the Mainframe as a
Modulation Source for External Devices (Synchro Output), p. 44 .
Procedure 1. Set up the wanted digital modulation to the DFB module using one of the following
methods:
• DFB module internal modulation source, as explained in section Setting Up
Digital (TTL) Modulation Using the DFB Module Internal Source, p. 75 .
• OSICS Mainframe internal modulation source, as explained in section Setting Up
Digital (TTL) Modulation Using the Mainframe Internal Source, p. 77 .
• OSICS Mainframe external modulation source, as explained in section Setting Up
Digital (TTL) Modulation Using an External Source, p. 80 .
2. Connect the wanted appropriate device to the OUT 2 BNC connector corresponding
to the channel slot number of the module.
The selected modulation frequency is applied to the connected device.
