My question is : 1) If i measure the 50 ohm load using handheld vector analyzer, do I need to calculate the return loss or just direct take the reading? 2) What is the pass fail criteria for 50 ohm load? does the impedance has range? 3) Does the frequency range impact the impedance? 4) while measuring the 50 ohm load, which measurement i need to refer to? VSWR or smith chart? My goals is I need to make sure the 50 ohm load terminator is in good condition. How do I know if the 50 ohm load still in good condition? I read multiple post regarding to the 50 ohm load but still dont get it the pass fail criteria. I've been measured the load using vector analyzer but don't understand the pass/fail criteria. The 50 ohm load been used multiple times and I need to check the measurement whether it still in good condition or not. Most RF systems are built around 50 impedance. Hi all, Currently I'm doing a project about 50 ohm load terminators measurement. The use of a standardized impedance makes RF design much more practical and efficient.
