Our product |
Domestic and foreign products |
|
Frequency accuracy |
0.001% |
0.01% or 0.005% |
|
Sampling accuracy |
100MSPS |
20MSPS |
|
Sinle phase test speed |
Within 1-2 minutes |
Mostly 5 minutes |
|
Output voltage |
Vpp-25V，Automatic adjustment during test |
Other manufacturers mostly use the 10V or 20V constant voltage method, and there is no automatic adjustment during the test, which affects the accuracy. |
|
Acquisition channel quantization accuracy |
18 bits |
Mostly 14 bits |
|
Load curve |
9 curves |
6 curves |
|
With oscilloscope function |
The waveform, peak-to-peak value and fitted sine wave waveform of the excitation signal and response signal can be displayed in real time. (An oscilloscope is built inside the instrument. This function is very useful. It displays the real-time curve and the test status from time to time!) |
At present, we have not found that other domestic and foreign manufacturers have this function |
|
Internal process design |
All are modular potting, subverting the traditional manual welding method of instruments |
Traditional manual welding method |
|
Communication Interface |
USB,Plug and play in real-time |
USB；Or other serial ports, sometimes receiving interference information |
