PERFORMANCE TESTS
4 - 22. INPUT ATTENUATOR ACCURACY
SPECIFICATION:
Step Accuracy
(0 dB to 60 dB):
< k 1.0 dB per 10 - dB step, 0.01 to 18.0 GHz
Maximum Cumulative Step Error (0 dB to 60 dB):
< 2.4 dB, 0.01 to 18.0 GHz
DESCRIPTION:
The input attenuator accuracy is tested over the range of
0 to 60 dB using an RF substitution method. A step
attenuator that has been calibrated at 30 MHz by a Standards Laboratory is used for substitution. The known
error of the calibrated attenuator is taken into account when computing the input attenuator accuracy.
