attach both coax cables to the female to female connector.If the frequency window or power level ever changes the device must be re calibrated.įull 2 Port Calibration (reflections and transmissions in both directions) You are now ready to take one port measurements. replace the short load with the 50 ohm load and press the LOAD soft key.
replace the open load with the short load and press the SHORT soft key.( IMPORTANT: Never twist calibration loads and hold the tension wrench at the very end!!! failure to do this can damage the center conductors and ports) then press the OPEN soft key. Attach the Open calibration load to the coax cable on port 1 and torque it down with the calibrated tension wrench while using a second 5/16th inch wrench to hold the calibration load steady.for a 1-port measurement press the S11 1-PORT soft key.For best results let the VNA worm up for 30min prior to calibrating.For a single port measurement skip this step. QUAD SETUP, and then DUAL CHAN to turn both ports on. for a 2 port measurement press Display, DUAL.for a 2 port measurement repeat steps 7 and 8 for port 2.touch the ends of the coax cables to discharge any built up energy and then screw one end into port one by hand, use the calibrated tension wrench to torque the SMA connector the rest of the way.carefully remove the rubber SMA protectors from the VNA and coax cables and place them in a safe spot so they won’t get lost.press the POWER RANGES soft key and then the corresponding power range that is desired.if needed, set the stimulus power by pressing the menu button in the stimulus group, then press the soft key labeled PWR RANGE to switch to manual mode.Set the ending frequency point by pressing the stop bottom in the stimulus group than typing in the frequency and unit as before in step 3.
Set the starting frequency point by pressing the start bottom in the stimulus group than typing in the frequency on the number pad and then the frequency units located on the right side of the number pad (G,M,K,X1(Hz)).
