The Agilent 83438A—At a Glance
The output can be modulated or turned off
You can digitally modulate the output using a TTL compatible signal. For a
complete discussion of modulating the output light and making measurements
with your Agilent 83438A, refer to
Chapter 2, “Making Measurements” .
Measurement accuracy—it’s up to you!
Fiber-optic connectors are easily damaged when connected to dirty or damaged cables
and accessories. The Agilent 83438A’s front-panel OPTICAL OUT connector is no excep-
tion. When you use improper cleaning and handling techniques, you risk expensive
instrument repairs, damaged cables, and compromised measurements.
Before you connect any fiber-optic cable to the Agilent 83438A, refer to “Cleaning Con-
nections for Accurate Measurements” on page 2-11 .
Laser classification
The Agilent 83438A is classified as an IEC LASER Class 1. The total power of light
energy radiated out of the OPTICAL OUT connector is no greater than +8.1 dBm (6.5 mW)
at a wavelength of 1550 nm. Operator maintenance or precautions are not necessary to
maintain safety. No controls, adjustments, or performance of procedures result in haz-
ardous radiation exposure.
