Noisecom UFX-7905

The UFX7000 Series noise generating instruments are extremely easy to use, combining dedicated keys for control of operations and programming with a large 4 x 20 character LCD display for instant status information.

.

The instruments are direct replacements for Noise Com's NC7000 Series instruments. The UFX7000 Series instruments contain a Noise Com amplified noise source that is tuned to provide the best flatness at the instrument output. The amplifier is 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 state is controlled by an RF 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 instrument's flexible architecture allows many options to be specified:

• Switched filter bank: Acts on noise and allows up to four filters to be connected. The filters can be specified in any combination of bandpass, lowpass, highpass, or notch. A thru line and set of terminations (RF loads) are also included. If no filters are specified, filter connections are supplied on the back panel. Available on signal side also.
• Output combiner: Allows the user to inject a signal and add a controlled amount of noise.
• Signal attenuator: Available in 0.1 or 1 dB steps to 127 dB.

The instruments allow the noise attenuator, noise filter, signal attenuator values, step size, and signal filter setting to be selected in three ways: at the front panel keypad, remotely via IEEE-488 bus, or automatically under program control.

Every front panel operation except instrument on/off is programmable. Programs are easily written using the program key, and information on the display guides the user through the next steps. Nine user-created programs that contain subroutines, delay times, and loops can be stored in non-volatile memory

• Front panel SMA output (standard config)
