Figure 3 illustrates the possible memory usage of an ni signal generator.
Arbitrary waveform generator ni.
Ni signal generators store multiple waveforms in onboard memory.
The maximum rate allowed for arbitrary waveforms uploaded to the pxie 5413 and pxie 5423 is 200.
Common types of waveforms outputs include sine wave square wave ramp or triangular wave pulse wave cardiac pattern wave gaussian pulse waves arbitrary waves.
Arbitrary waveform generators allow you to generate a user defined waveform of any size unlike an arbitrary function generator which can only generate a custom periodic waveform.
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.
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.
Figure 3 shows that waveforms stored on a signal generator can occupy a significant amount of memory.
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.
The ni 5412 can out waveforms of size 4 8 12 16 and so on while the former could only output waveforms of size.
These instruments are ideal for applications in scientific research and testing of consumer electronics automotive and aerospace defense.
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.
Nifgen create waveform i16 creates an onboard waveform from i16 data for use in arbitrary waveform or arbitrary sequence output mode.
Pxie 54x3 arbitrary waveform generators output all waveforms including standard and arbitrary waveforms with a dac update rate of 800 ms s.
For example a waveform sampled at 100 ms s for 1 second occupies 200 mb.
Keysight s high performance arbitrary waveform generators use low noise clocks which provide unmatched performance and high quality signal generation to achieve superior fidelity.
Waveform generators produce large complex analog waveforms in a sequential manner or using real time streaming.
This vi can also create an onboard waveform.
An algorithm implemented on the xilinx kintex 7 fpga is used to up sample user defined arbitrary waveforms.
Awgs operating in arbitrary waveform mode only generate each sample of the waveform that is stored in memory in order.
