A
Signal Outputs.
There are two signal outputs on the front panel of the tunable laser source
.
One of these is the Modulation Output, which outputs the internal signal used
to modulate the optical output. This is a squarewave signal with 50% duty
cycle, and is at TTL levels (see \Setting the Modulation Output" in Chapter 3
and \[:SOURCE]:MODOUT" in Chapter 5 for more information).
The other is the analog output, which outputs a voltage level proportional to
the power of the output laser signal. The relationship between this voltage
level and the output power is not calibrated, but is approximately 1mV for
each 1
W.
Caution
The maximum external voltages that can be applied to the
outputs of this instrument are
6
10V.
Optical Output
Caution
If the optical termination on your instrument is angled, you can
only use cables with angled connectors with the instrument.
See \Connector Interfaces and Other Accessories" in Appendix B for further
details on connector interfaces and accessories.
Option 007
If you have an instrument with a polarization maintaining ber
(PMF), the PMF will be automatically aligned and maintain the
state of polarization..
The ber is of Panda type, with T
E
mode in the slow axis in line
with the connector key.
