Tektronix (Keithley) 3390 Arbitrary Waveform/Function Generator
Features
Arbitrary Waveform Generation (ARB)
With the Model 3390, you can precisely replicate real world signals. This 14-bit ARB provides the ability to define waveforms with up to 256,000 data points and generate them at a sampling rate of 125MSamples/second. For ease of use, up to four user-defined waveforms can be stored in the onboard non-volatile memory.
Function Generation
Standard output waveforms can be created by pressing one button on the front panel. Ten standard waveforms are provided, including the basic sine, square, ramp, and triangle shapes. The Model 3390 offers the highest repetition rates of any instrument in its class, allowing you to better emulate the signals you need to test.
Pulse Generation
Pulse capabilities have become critically important as devices being tested have become smaller, more sensitive, and more complex. To accurately duplicate the signals these tiny devices receive, very clean pulses with crisp edges are mandatory, which is why the Model 3390 offers the fastest rise time (5ns) and cleanest pulse shapes for this class of instrument.
Modulating Waveforms
The ability of the Model 3390 to modulate at high internal frequencies allows you to accurately simulate real-world conditions. Modulate any of your signals with the built-in AM, FM, PM, PWM, or FSK source, or use your own external modulation source.
Noise Generation
Inject noise into your device under test with the press of a button. The adjustable amplitude and offset parameters control how much or how little noise is produced. The fast rise times and high speed capability provides the precise noise simulation your applications require.
