Analyzer Battery Information
The HP 8590 Series spectrum analyzers use a 3.6 V lithium battery to enable the spectrum
analyzer memory to retain data. The date when the battery was installed is on a label on the
rear panel of the spectrum analyzer. See Figure 2-10.
The minimum life expectancy of the battery is 8 years at 25 "C, or 1 year at 55 "C. If you
experience problems with the battery or the recommended time period for battery replacement
has elapsed, see "How to Return Your Analyzer for Service" in Chapter 9.
If you wish to replace the battery yourself, you can purchase the service documentation that
provides all necessary test and maintenance information. The battery is soldered onto the
spectrum analyzer processor board.
Warning
There is a danger of explosion if the battery is incorrectly replaced.
Replace only with the same or equivalent type recommended. Discard
used batteries according to manufacture's instructions.
You can order the service documentation for an HP 8590 Series spectrum analyzer through your
HP Sales and Service office. The documentation is described under "Service Documentation
(Option 915)" in Chapter 10 of this manual.
After replacing the spectrum analyzer battery, write the date of battery replacement on the
rear-panel label.
