PNG7000A Programmable Noise Generator Series
The PNG7000A Series instruments generate white Gaussian
noise and provide a summing input to control signal-to-noise
(SNR) or carrier-to-noise (CNR) for bit-error-ratio (BER)
testing. The output can also be used as a random source for
time domain Jitter applications. A key feature of this
instrument is its low distortion signal path that sums the
user-supplied signal with the internal precision white
noise source.
The signal path has a nominal insertion gain of 0 dB, with
very low amplitude and phase ripple. The noise source
provides an exceptionally high crest factor for accurate bit
error rate testing, even with large carrier-to-noise (CNR) or
bit energy-to-noise density (Eb/No) ratios. With the addition
of option 7, DC coupling will allow adding noise directly
to a digital TTL, ECL, or similar signal.
The standard PNG7000A is a broadband device, but for
applications that require a greater range, the unit can be
configured with up to five band-limited noise sources, each
optimized for flatness over the specified frequency band.
Noise Com will modilfy base units for specific customer
needs. For pricing and availablity, consult the factory.
The PNG7000A 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 remotely via IEEE-488 bus, Ethernet, or Serial type
RS232. The PNG7000A instruments can be integrated into
a test station under software control, and with the aid of a
precision power meter the C/N or Eb/No ratios can be set.

• Noise attenuator ±0.2 dB or 0.5% accuracy
at 1 - 500 MHz
• ±0.2 dB or 1% at 0.5 - 1.0 GHz
• ±0.3 dB or 2% at 1 - 2 GHz

Once a CNR calibration has been performed, the ratio can
be changed using the internal precision attenuator to vary
the noise power without degrading accuracy. The output
noise power level is factory calibrated at a 0 dB attenuator
setting and is displayed in dBm/Hz.
