On the calibrate, the firmware routine does not appear quite right.
In any case, what I found that works consistent is the following:
1. Select stimulus and start and stop frequency
2. Select CAL and then CALIBRATE
3. Connect the 50 ohm to CH0
4. Press LOAD and then PRESS ISOLN (Note these are highlighted in black at first and then ISOLN goes green)
5. Then connect a THRU cable form CH0 to CH1 and press THRU
6. The firmware takes you to DONE. IGNORE!!!!
7. Now connect an OPEN to CH0
8. Press OPEN
9. Connect a SHORT to CH0
10. Press SHORT
11. Then finally press DONE
12. And SAVE
That's it. Check and be sure that the open, short and 50 ohm are on the proper side of the chart.

P.S. Let me know if not clear or if I missed something. NOTE, this is for the 2 trace or 2 track VNA. Not the 4 track or S11/S21 measurement device. Although I suspect the cal routine is no different.

Hello all. I have the same instructions, plan to do someday in Portuguese. At time the most confused part is the calibration, didn’T figure yet if it take long to stabilize, if its like put open, short and load and press calibrate...
