Applications
154 Agilent 8163A Lightwave Multimeter, Agilent 8164A Lightwave Measurement 
System, & Agilent 8166A Lightwave Multichannel System, Fourth Edition
This chapter explains how to set up and perform the following applications using 
the Agilent 8163A Lightwave Multimeter or Agilent 8164A Lightwave 
Measurement System:
• The Logging application logs and displays power measurements. The Logging 
application performs measurements consecutively without the possibility of 
any pause between measurements. 
• The Stability application logs and displays power measurements. The Stability 
application differs from the Logging application because:
– you may use auto-ranging mode, and
– the period time, the time it takes from the start of one measurement period 
until another measurement period starts, may be greater than or equal to the 
averaging time.
• The PACT application coordinates a wavelength sweep using a Tunable Laser 
module and power measurement using Power Meters. 
• The Pmax Curve application displays the maximum power across the 
wavelength range of your Tunable Laser module.
NOTE These applications are not available for the Agilent 8166A Lightwave 
Multichannel System.
You can access these applications by pressing the Appl hardkey.
NOTE After you exit from the application, any modules that were available for use by 
these applications will automatically be preset, all parameters will be set to their 
default values.
