The 3155 is a cost effective alternative to a GPIB-based waveform generator for use in a PXI-based test system. It provides a synergistic combination of a function generator, arbitrary waveform synthesizer, programmable sequencer, pulse generator, and modulation generator in one instrument. This versatility ensures that the 3155 will adapt to future testing needs as well as current ones.
The 3155 comes with WaveCAD for designing arbitrary waveforms. Waveform coordinates can be imported from a variety of sources such as Matlab, Excel, ASCII files, etc. Also, multiple 3155 units can be placed in a PXI chassis such as the Racal Instruments™ 1461-14 for multi-instrument synchronization to create multiple, phase controlled output channels. Then, you may vary module-to-module phase offsets to create a multi-phase signal source.
New technology requirements continue to drive test systems to use increasingly narrow channel widths. A high sample rate of 100 MS/s makes the 3155 an ideal modulation source for troubleshooting new encoding schemes. The 3155 also provides high-speed waveforms to simulate signal distortion, power line cycle dropouts, video signals, component failures, and power supply transients.
The 3155 provides 2 Meg of segmentable waveform memory accessible via a high-speed interface, and a storage capacity of up to 4096 different waveforms of variable size. This allows test software to rapidly switch between several different waveforms without multiple downloads.
With the 3155’s WaveCAD software, you control the instrument’s functions, modes, and features. In addition, one can create a virtually unlimited variety of test waveforms: Freehand sketch and the built-in equation editor allow custom waveform design for quick analysis of analog signals. A typical application is to add or subtract components of a Fourier series for digital or analog filter characterization, or to inject random noise into a signal to test immunity to auxiliary noise.
Another unique and valuable feature of WaveCAD is the FM Composer. The FM composer is similar to the Wave Composer screen except that the vertical axis is given in units of frequency also. You can create any arbitrary waveform shape or even use the equation editor to generate exotic shapes to frequency modulate the output.
Powerful sequencing capability allows linkage of up to 4096 waveform segments and/or bursts (repeated segments) into strings. Each segment can be repeated up to 128 k times in burst mode. Sequenced functions can run continuously or be initiated by a trigger. Also, one can mix continuous and triggered segments within one sequence. These sequencing features allow the creation of complex waveforms or pulse patterns using minimal amounts of memory.
Using WaveCAD, sequences are created via a sequence table. Sequence table download is extremely fast as the program writes directly to waveform and sequencer memory, thus bypassing the embedded controller.
The 3155 has outstanding low phase noise and carrier stability, requirements for telecommunication and channel separation applications. The output of the 3155 is also highly agile for applications needing sweep, FSK, and FM. Direct Digital Synthesis (DDS) supports applications such as wide-band FM, and wander with arbitrary chirp profiles.
Combining PXI bus trigger lines with the 3155 sync capability transforms the 3155 into an Arbitrary Trigger Generator. In addition to continuous output, the instrument can also wait for a trigger to initiate a single waveform, a burst of waveforms, or a sequence of waveforms. Triggers can also be used to advance a sequence of waveforms, one segment at a time. The 3155 accepts the triggers for multiple sources: eight backplane trigger lines plus the STAR trigger, front panel trigger input, and manual commands such as *TRG.

Great company staff is extremely knowledgeable!!
I find the employees helpful and knowledgeable about their products.
We bought a Parker Compumotor Controller for our press and installed it 2 weeks ago. Easy fix for our machine and it is working perfect.
I just want to thank you and the staff at Artisan for your prompt dispatch of the 34401A main board. I got it a couple of hrs. ago, removed the old board, installed the new and the result is as shown in the attachment. It not only works, but is calibrated to the last digit! I am very pleased and will definitely recommend your firm to my friends and colleagues. I really appreciate doing business with a firm that values service.
