Getting Started

This chapter shows you how to install and maintain the HP 71910A and its various options.

In addition, there is a procedure for installing an HP 70911A wide bandwidth IF module into

an existing HP 71209A Option 001 spectrum analyzer.

No sp ecial tools are required except for the pro cedure \To install an HP 70911A in your

HP 71209A." This procedure requires an 8 mm ball driver. Be careful to observe all notes,

cautions, and warnings in the pro cedures.
