Using Modules
How to Fit and Remove Modules
You can use two types of module:
• Front-loadable modules - these modules fit in the four module slots at
the front of the 8164A/B Lightwave Measurement System or the two
module slots at the front of the 8163A/B Lightwave Multimeter System
or the 17 module slots at the front of the 8166A/B Lightwave
Multichannel System.
• Back-loadable modules - these tunable laser source modules fit in the
large module slot at the rear of the 8164A/B Lightwave Measurement
System.
How to Remove a Front-Loadable Module
Do not use the electrical or optical connectors to pull the module out of
the instrument, as this can cause damage to the connectors.
Make sure that the line power is switched off before you remove a
module.
