Description of the E4421A signal generator:
The E4421A analog RF signal generator offers excellent in-channel
performance
with superior quality and reliability -- at an affordable price. The first in a new
gener
ation of signal generators, it provides excellent frequency and level control,
and wide
modulation capabilities. It is ideally suited to meet the demanding
requirements of
today's receiver test, component test and local oscillator applications. The
innovative
design of the E4421A provides a flexible architecture that can be tailored to
meet the
changing demands of evolving markets. Lower initial cost, high reliability and a
two-year
calibration cycle, all strive to minimize the cost of ownership. The E4421A RF
signal
generator is designed for long-term dependability, which maximizes
production throughput
and uptime.
