The UFX7000A Series instruments contain an amplified noise source that is tuned to provide the best flatness and optimized 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 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.
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 remotely via IEEE-488 bus, ethernet, or serial type RS232. The UFX7000A series instruments can be integrated into an ATE test station.
