Specifications subject to change without notice.
The UFX7000 Series noise generating
i n s t r uments are extremely easy to use,
combining dedicated keys for control of
operations and programming with a large
4 x 20 character LCD display for instant status
i n f o r mation. The instruments are direct
replacements for Noise Com’s NC7000 Series
i n s t r uments.
The U F X 7 0 0 0
S e r i e s i n s t r u-
ments contain
a Noise Com
amplified
noise sourc e
that is tuned
to provide
the best
flatness at the
i n s t r ument output.
The amplifier is opti-
mized to deliver an output
with a Gaussian amplitude distribution. Noise
output power level can be adjusted from 0 to
127 dB in 1 dB (optionally 0.1 dB) steps.
The output state is controlled by an RF switch.
In the standby state, the noise is terminated
into an RF load and in the “on” state it is
d i r ected to the output connector.
The instrument's flexible arc h i t e c t u r e allows
many options to be specified:
Switched filter bank: Acts on noise and
allows up to four filters to be connected. The
filters can be specified in any combination
of bandpass, lowpass, highpass, or notch. A
t h r u line and set of terminations (RF loads) are
also included. If no filters are specified, filter
connections are supplied on the back panel.
Available on signal side also.
Output combiner: Allows the user to inject a
signal and add a controlled amount of noise.
Signal attenuator: Available in 0.1 or 1 dB
steps to 127 dB.

The instruments allow the noise attenuator, noise
f i l t e r, signal attenuator values, step size, and signal
filter setting to be selected in three ways: at the
f r ont panel keypad, remotely via IEEE-488 bus, or
automatically under program contro l .
E v e r y front panel operation except instru m e n t
o n / o f f is programmable. Programs are easily written
using the program key, and information on the
display guides the user through the next steps. Nine
u s e r - c r eated programs that contain subro u t i n e s ,
delay times, and loops can be stored in non-volatile
m e m o r y.
Applications:
• E l e c t romagnetic susceptibility
• Filter testing
• C ATV gain (tilt) alignment
• Image and spurious rejection tests
• GPS re c e i v e r s
• Disk drive testing
• S p e c t rum analyzer calibration
• Jamming systems
• Signal to noise measure m e n t
