D displays You must judge whether the error is tolerable in the particular application and how to compensate for the change The application question is Does increasing the signal level during calibration improve the calibration enough to risk a possible increase in error contributions when you change the setup The only reason for changing an internal attenuator or external equipment between calibrations and measurements is to maximize the signal level under both conditions thus minimizing uncertainty due to noise Many factors enter into a setup change decision for example isit more accurate to calibrate at a low signal level without changing the setup or is it more accurate to change the setup to optimize levels for both the calibration and measurement Changing attenuators at Port 1 or Port 2 does not change the test set mismatch directivity or isolation characteristics severely It does change the frequency response magnitude and phase however The difference between frequency response calibration and measurement can be normalized by using HP 8510C trace memories If only the attenuators at Port 1 or Port 2 are changed use the following procedure to minimize errors 1 Connect a short or a thru and set Port 1 and Port 2 attenuators for the best IF signal levels during calibration 2 Perform the appropriate measurement calibration 3 Connect the correct calibration standard set Port 1 and Port 2 attenuat
