FPGA refers to on-line programmable logic gate array, a semi custom circuit in ASIC
ADC refers to analog-to-digital converter
DAC exponential to analog converter
Indicates the number of waveform samples collected per second.
The higher the sampling rate is, the closer the digital signal is to the real analog signal. If the sampling rate is insufficient, distortion may occur
ADC resolution refers to the maximum number of bits that can be represented by analog-to-digital converter. High resolution is a necessary condition for high precision
Waveform refresh rate refers to the number of waveform frames that can be collected per second. The higher the refresh rate, the smaller the acquisition dead time, and the easier it is to capture abnormal signals
Storage depth refers to the ability to store information. The greater the storage depth, the more samples can be stored, and the greater the amount of information that can be analyzed
The highest output frequency refers to the highest sine wave frequency that can be output
Vertical resolution refers to the minimum amplitude that the output signal can distinguish. The higher the resolution, the more accurate the output signal is
Output jitter refers to the offset of a signal from its ideal time position when it jumps. The smaller the output jitter, the more accurate the output signal
Phase noise refers to the spectral purity of the signal, which can affect the performance of the modulated signal. The smaller the phase noise, the better the output signal performance
The output power range refers to the power range of the output signal. The larger the output range, the richer the application scenarios
RF output bandwidth refers to the modulation bandwidth range that the signal generator can support. The larger the RF output bandwidth, the richer the application scenarios
The displayed average noise level refers to the minimum level that can be measured by the spectrum analyzer. The higher the average noise level, the smaller the measurement sensitivity
Real time analysis bandwidth refers to real-time spectrum and signal analysis bandwidth. The larger the real-time analysis bandwidth, the richer the application scenarios
The minimum signal width of 100% POI refers to the shortest signal time width that can be found with 100% probability within the analysis bandwidth. The smaller the minimum signal width of 100% POI, the stronger the signal acquisition ability
Directivity refers to the ability of the port of vector network analyzer to separate the measured signal. The greater the directivity, the better, and the stronger the separation ability of the measured signal
Dynamic range refers to the difference between the maximum signal and the minimum signal that can be measured at the same time. The larger the dynamic range, the better the application field
