UFX 7000A Programmable Noise Generator Series

he UFX7000ASeries instruments contain an amplified

T
noise source that is tuned to provide the best flatness and

ptimized to deliver an output with a Gaussian amplitude

o
distribution. Noise output power level can be adjusted from
0 to 127 dB in 1 dB (optionally 0.1 dB) steps. The output
signal is controlled by an RF type 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 UFX7000A Series flexible architecture allows many
options to be specified. An internal combiner allows the user
to inject an external signal via a front panel connector to
add a controlled amount of noise. Noise Com will modilfy
base units for specific customer needs. For pricing and
availablity, consult the factory.

Optional signal attenuation is available up to 127 dB, in 0.1
or 1 dB steps . A switching filter bank in the noise path
allows up to four filters to be connected. The optional filters
can be specified in any combination of band pass, low pass,
high pass, or notch, with a thru line and 50 Ohm termination
(RF load) included. Connectors on the back panel provide a
pathway for the external filters to the internal combiner
and the front panel instrument output.

The UFX7000A Series is microprocessor-controlled and
provides information about operation of the instrument via
a 6.25” color TFT display. Control of the noise level, noise
on/off switching, signal on/off switching, and noise source
selection can be controlled either manually by the touch
screen, or r
RS232. The UFX7000A series instruments can be integrated
into an A

emotely via IEEE-488 bus, ethernet, or serial type

TE test station.
