Easy, Economical, One-Box Pager Testing 1
Using the HP 8648A Option 1EP
The HP 8648A Option 1EP provides a complete, economical, one-box
pager test solution. It includes the digital pager encoder that supports
the popular worldwide standard, POCSAG (Post Office Code Standardization Advisory Group), and the newer paging standards, FLEX and
FLEX-TD (RCR-43, for Japan).
Offering Key FLEX Specifications
The specifications of the HP 8648A Option 1EP are ideal for the strin-
11
gent FLEX and FLEX-TD test requirements. It offers 60 Hz frequency
shift keying (FSK) deviation accuracy within specific pager service
bands. This is the most important FLEX specification. Also, it typically
offers 40 Hz car rier frequency accuracy (relative to CW in dcFM).
Faster, Easier Testing
Now test time is reduced and simplified with the HP 8648A’s semiautomated features:
• Customize your result with user-defined messages of up to
40 characters
• Reduce test time with 5 built-in test messages
• Increase test reliability with 70 internal storage registers
capable of storing the entire protocol configuration
