UFX 7000A Programmable Noise Generator Series
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. 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 remotely via IEEE-488 bus, ethernet, or serial type RS232. The UFX7000A series instruments can be integrated into an ATE test station.
