Calibration and Normalization
The VNA Master is a field portable unit operating in the rigors of the test environment. In order to ensure
measurement accuracy, RF calibration (SOLT) must be performed prior to making a measurement in the field.
Calibrating with the specified mechanical calibration requires three calibration parts: open, short, and
match(load) and one RG316 RF cable. Calibration data is saved as user calibration data. It can be saved to
status 0/1/2/3/4, which will be automatically loaded at the next boot and can be also be loaded via the RECALL
menu.
The figure below shows the OPEN, SHORT, and LOAD calibration components that are standard with the
NanoVNA-F.
Brief summary of NanoVNA-F calibration steps:
1) Open CAL menu and press RESET
2) Open CALIBRATE menu
3) Connect SMA Open to PORT1 wait more than 3 seconds (wait for the screen to stabilize) and press OPEN
4) Connect SMA Short to PORT1 wait more than 3 seconds (wait for the screen to stabilize) and press SHORT
5) Connect SMA Load to PORT1 wait more than 3 seconds (wait for the screen to stabilize) and press LOAD
6) Connect SMA Load to PORT1, connect second Load to PORT2, wait more than 3 seconds (wait for the
screen to stabilize) and press ISOLN
Note: if you don't have second Load, just leave PORT2 open.
7) Connect RF cable from PORT1 to PORT2 wait more than 3 seconds (wait for the screen to stabilize) and
press THRU
8) Press DONE, save to 0/1/2/3/4 one of them.
Note: If there is already saved calibration data, first press “Reset” to clear the calibration data and then
calibrate!
If you make a mistake, start again with RESET!
Once the calibration is complete, the three calibrators can be connected to PORT1 again, and the correct
calibration should be based on the S11 SMITH chart, which should be:
