Keysight Technologies Inc. N5172B-403 Calibrated AWGN, fixed perpetual license

Signal creation

• Add AWGN to any signal played by arbitrary waveform or real-time baseband generator
• Generate standalone AWGN for use as a general purpose noise source
• Set AGWN level as a C/N ratio from the front panel
• Set Eb/No, Ec/No, or C/N from Signal Studio software

Real-time mode

• Noise bandwidth: 1 Hz to 120 MHz
• Crest factor: 15 dB
• Randomness: 90 bit pseudo-random generation
• Repetition period: 313 x 10E9 years

Other features

• Internal software application built-in to signal generator firmware; no PC required

Transform the EXG into a flexible noise source

Option 403 enables the creation of real-time, uncorrelated additive white Gaussian noise (AWGN). This real-time mode of operation generates truly uncorrelated noise with a noise bandwidth that can be continuously varied up to 120 MHz.

Combine calibrated AWGN with signals from the EXG

Add noise directly to any arbitrary waveform played back using the EXG internal baseband generator and adjust the noise power precisely with digital accuracy. Also set the noise level directly from the user interface of many Signal Studio signal creation software applications.

Typical application

The calibrated noise option is recommended for flexible standalone AWGN generation, and for setting signal-to-noise ratios directly in the Keysight MXG or with select Signal Studio software. The uncorrelated nature of the test stimulus is ideal for generating noise interference and is especially important for determining receiver performance.

This option can be added as a product upgrade.
