7. DYNAMIC ACCURACY TEST

Description

This test checks the dynamic accuracy of the E5071C. The dynamic accuracy is tested at
1.195 GHz for each receiver port using the Agilent Z5623A (with option H01) Dynamic
Accuracy Test Kit. The 1.195 GHz source signal of the E5071C goes through the Z5623A's
first attenuator variable from 0 dB to 11 dB in 1 dB steps and second attenuator variable up
to 100 dB in 10 dB steps and is measured with the receiver port. The test procedure checks
the measured receiver-input power for each 5 dB increment in the range from 10 dBm to
100 dBm. The ratios of the measured receiver-input powers to the reference input level of
-10 dBm are calculated and compared to the attenuation values of the Z5623A. The 1.195
GHz signal flow is split with a power splitter present between the two attenuators in the
Z5623A and measured with an external power meter to calibrate the attenuated power
level.
NOTE Since the dynamic accuracy does not have frequency dependence, this test is performed at
1.195 GHz only.
