HP 4284A Calibration
Accuracy
Calibration accuracy is shown in the following gure.
f
m
: test frequency [kHz]
On boundary line apply the b etter value.
Upper value (A
cal
)is j Z j , j Y j , L, C, R, X, G and B calibration
accuracy [%].
Lower value ( 
cal
) is phase calibration accuracy in radians.
