HP 8656/57 Series
Synthesized Signal
Generators
The HP 8656157 series is
designed to meet the testing
needs of the communication
industry.
Test AM, FM, and
pulsed receivers as well as
components. Use it in R&D,
manufacturing, and support.
There are six signal generators
in the family, all offering
exceptional analog modulation,
good spectral purity, and superb
output level performance.
HP 8657D
The HP 8657D adds d4 DQPSK
modulation. Test radios
designed for the North
American Digital Cellular Radio
System and Japanese Digital
Cellular
System.
HP 8657A/B Option 022
For European digital
communication sys terns, the
HP 8657- Option 022
generates 0.3 Gaussian
Minimum Shift Keying (0.3
GMSK). Test receivers designed
for the GSM Pan-European
Di~tal Cellular Radio System
and the PCN European
Personal Communications
Network.
