Specifications subject to change without notice.
The NC5000 Series noise sources feature
outstanding stability, switching speed, and
ripple-free response over standard waveguide
bands. The high stability of the NC5000 Series
allows these units to be used in place of
cumbersome gas tube noise sources.
Ripple in the output of noise sources has a
direct effect on measurement accuracy,
so Noise Com has tailored the
response of the NC5000
Series so that ripple
is minimized
throughout
the specified
frequency range.
The NC5000 Series
is available with
noise output of
15.5 dB for
instrumentation (noise
figure meter) applications,
as well as in narrow and full
waveguide bands with 15 to 25 dB ENR
output. The standard input bias connector is
BNC female; others are available.
Applications:
• Noise figure measurement
• Built-in test equipment (BITE)
• Military applications
• Radiometers
