27.4 Display Accuracy of Frequency Span
Adjust the frequency of the calibration equipment so that the peaks are at the positions of f 1 and f 9 , and
measure the frequencies of f 1 and f 9 . Calculate from f 1 and f 9 the display accuracy of the frequency span.
* f 1 : 1 st div from the left on the spectrum display
f 9 : 9 th div from the left on the spectrum display

27.5 Linearity of Amplitude Axis
Adjust the level of the calibration unit so that the peak is at the top of the amplitude axis (0th div), and regard the
point set at that time as the reference. Gradually lower the output, starting from the reference, and measure the
amplitude value of 2650A/2652A/2651/2658A.
