195 Universal Waveform Generator |
|
The 195 includes a 40 MS/s arbitrary waveform generator with 12 bits of vertical resolution and 64k points of waveform memory per channel. Extensive waveform editing features are incorporated, including waveform insert, point edit, line draw, amplitude adjusts and invert. Up to 100 waveforms may be stored in the 195's non-volatile memory.
Synthesized function generatorThe 195 is also a synthesized function generator that provides sine and square waves up to 16 MHz. Other standard functions include DC, positive ramp, negative ramp, pulse, pulse train, sin (x)/x, cosine, haversine and havercosine waveforms. With 7 digit resolution and 10 ppm accuracy for sine waves, the 195 is ideal for multi-channel applications requiring standard functions.
Phase lockingTwo or more channels can be phase locked together. Slave channels can be offset with respect to the assigned master channel. Phase resolution is 0.1° for standard functions and 360°/number of waveform points for arbitrary waveforms. Multiple 195s can be phase locked together for applications requiring more than 4 phase locked channels.
Pulse and pulse trainThe 195 has a built-in pulse generator capable of generating far more complex pulses than typical pulse generators. In addition to single pulses at up to 10MHz, the 195 generates complex pulse trains of up to 10 pulses. Each individual pulse has independently programmed width, level and delay. This versatility makes the 195 suitable for applications as diverse as video, automotive, communications, medical and semiconductor device testing.
SummingWaveforms from two adjacent channels may be summed to create modulated signals or signal plus noise. Any waveforms can be summed.
Tone generatorThe 195 includes Tone Generator capability for all waveforms except pulse, pulse train and sequences. Up to 16 frequencies between 1 mHz and 10 MHz can be listed for setting up complex tone generation signals. Switching between frequencies can be synchronously or asynchronously triggered from a front panel key, an adjacent channel, the internal trigger generator, an external signal or by remote command. Outputs from 2 channels can be summed together for generating DTMF test signals.
Waveform sequencingFor long or very complex waveforms, up to 16 waveforms may be linked together to form a sequence of waveforms. Each waveform may have a user defined repeat, or loop count from 1 to 32768. Transition from one waveform to the next occurs phase continuously.
Waveform DSP2More comprehensive features are available using Fluke's WaveForm DSP2 arbitrary waveform creation software. WaveForm DSP2 is a powerful tool for creating complex waveforms and downloading them to Fluke's Universal Waveform Generators. Waveforms can be created using any combination of drawing, math expression, uploading signals from DSOs, the supplied library of waveforms or by importing files from other applications such as Microsoft Excel®. The standard Windows®. interface makes cutting, copying, pasting, and editing sections of waveforms easy.
WaveForm DSP2 easily switches between time and frequency domains. Powerful editing, drawing, and library features are available in either domain. For example, capture a signal with a DSO, upload to WaveForm DSP2, and view the waveform in the frequency domain to analyze its frequency content. You can add frequency spurs, change frequency content, or manipulate phase relationships. Then switch to the time domain and view your new waveshape.
A library of waveforms is included with WaveForm DSP2. And it is easy to add waveforms to the library as you create them.
Amplitude modulationAmplitude Modulation and Suppressed Carrier Modulation is available for all waveforms and can be controlled from another channel in the 195 or from an external signal.
