نتورک آنالایزر جیبی 50KHz to 3000MHz
NanoVNA V2 (S-A-A-2) is a low cost 3GHz T/R vector network analyzer developed by HCXQS in collaboration with OwOComm. The V2 hardware is a new from-scratch design and is not based on the original NanoVNA by edy555. Compared to the original NanoVNA, V2 does not use harmonics for measurements and achieves higher dynamic range.

VNA basics
A VNA (Vector Network Analyzer) measures the frequency dependent reflected and transmitted power of a high frequency network (RF Network).
The NanoVNA V2 measures the following:
Reflection coefficient: S11
Transmission coefficient: S21
The following items that can be calculated from these can be displayed:
Return loss
Insertion loss
Complex impedance
Resistance
Reactance
SWR
Required components
To use the NanoVNA V2 for one port measurements (e.g. antenna impedance), you will need the following:
NanoVNA V2 main unit
SMA cable, male-male
Calibration standards: Short, Open, and Load
Performing measurements
The basic operation and menu structure of the NanoVNA V2 is very similar to the original NanoVNA.
Configure the measurement frequency range:
Select STIMULUS > START and STIMULUS > STOP.
Calibrate:Enter the CAL menu and connect a SMA male-male cable to port 1 of the VNA.
Connect the OPEN standard to the cable end and select "OPEN". Wait for menu highlight.
Connect the SHORT standard to the cable end and select "SHORT". Wait for menu highlight.
Connect the LOAD standard to the cable end and select "LOAD". Wait for menu highlight.
Select "APPLY". Calibration should now be active and you can start performing measurements.
مرسی
خوب بود ممنون. کاش vna های پیشرفته تر هم گذاشته بودین. مثلاً vna6000 یا librevna یا liteVNA. حیف شد باز همینم کار راه اندازه. مرسی. یه نکته فاجعه. در لیست محصولاتتون، موجودی یا عدم موجودی ذکر نشده.
