Analysis and Research on the Centimeter Band Receiver Amplitude Calibration Method

Table 7

Accuracy calculation results of the chopper wheel method at 90°.

T rec (K)			(%)
381.7	114.1	10.68	2.8
381.7	119.69	10.94	2.87
381.7	124.2	11.14	2.92
381.7	108.6	10.42	2.73
381.7	119.67	10.94	2.86

Similarly, Tables 8 and 9 show the test accuracy of each group of the chopper wheel method at 30° and 5° elevation angles.
