An algorithm implemented on the xilinx kintex 7 fpga is used to up sample user defined arbitrary waveforms.
Arbitrary waveform generator ni.
Common types of waveforms outputs include sine wave square wave ramp or triangular wave pulse wave cardiac pattern wave gaussian pulse waves arbitrary waves.
Keysight s high performance arbitrary waveform generators offer clean complex and real world signals with bench top system ready axie lxi or pxi form factors.
Nifgen create waveform i16 creates an onboard waveform from i16 data for use in arbitrary waveform or arbitrary sequence output mode.
The waveform handle returned by the vi can be used later for setting the active waveform changing the data in the waveform building sequences of waveforms or deleting the waveform when it is no longer needed.
This vi can also create an onboard waveform.
For example the ni 5412 arbitrary waveform generators which has a minimum waveform size of 4 and a waveform quantum of 4 is more flexible than its predecessor which had a minimum waveform size of 256 and a quantum of 8 samples.
Awgs operating in arbitrary waveform mode only generate each sample of the waveform that is stored in memory in order.
The ni 5412 can out waveforms of size 4 8 12 16 and so on while the former could only output waveforms of size.
For example a waveform sampled at 100 ms s for 1 second occupies 200 mb.
Figure 3 shows that waveforms stored on a signal generator can occupy a significant amount of memory.
Figure 3 illustrates the possible memory usage of an ni signal generator.
Leap forward with keysight s awgs.
The maximum rate allowed for arbitrary waveforms uploaded to the pxie 5413 and pxie 5423 is 200.
Pxi waveform generators can produce precise waveforms including sine square triangle and ramp as well as arbitrary user defined waveforms using sequences of data or streaming continuously from a host or peer to peer instrument within the pxi system.
Solution although the dcpower and the smu cards like the pxie 4139 were not designed to be used as a function or waveform generator it is possible to program the card to output standard functions by translating the desired frequency and amplitude or a predefined arbitrary waveform to a continuous output sequence with voltage levels and source delays corrected by the intersample delays of the.
Ni signal generators store multiple waveforms in onboard memory.
A waveform generator is a classification of a signal generator used to generate electrical waveforms over a wide range of signals.
These instruments are ideal for applications in scientific research and testing of consumer electronics automotive and aerospace defense.
Keysight s high performance arbitrary waveform generators use low noise clocks which provide unmatched performance and high quality signal generation to achieve superior fidelity.
