The UFX7000 Series noise generating
instruments 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
information. The instruments are direct
replacements for Noise Com's NC7000 Series
instruments.
The UFX7000
Series instru-
ments contain
a Noise Com
amplified
noise source
that is tuned
to provide
the best
flatness at the
instrument 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
directed to the output connector.
The instrument's flexible architecture 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
thru 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
filter, signal attenuator values, step size, and signal
filter setting to be selected in three ways: at the
front panel keypad, remotely via IEEE-488 bus, or
automatically under program control.
Every front panel operation except instrument
on/off is programmable. Programs are easily written
using the program key, and information on the
display guides the user through the next steps. Nine
user-created programs that contain subroutines,
delay times, and loops can be stored in non-volatile
memory.
Applications:
• Electromagnetic susceptibility
• Filter testing
• CATV gain (tilt) alignment
• Image and spurious rejection tests
• GPS receivers
• Disk drive testing
• Spectrum analyzer calibration
• Jamming systems
• Signal to noise measurement
