Dynamic Accuracy Test - Agilent Technologies ENA Series Service Manual

the E5061A/E5062A. The system dynamic range is tested by performing an "Isolation"
measurement 16 times with segment sweep points for specified frequency ranges (same as
the crosstalk test). The measurement data for each sweep frequency point is substracted
from the crosstalk data which is measured by the crosstalk test, and calculating the RMS
deviation value from the 16 measurement data for each sweep frequency point. The
maximum RMS deviation value in each frequency range is extracted to determine the
system dynamic range performance.

6. Dynamic Accuracy Test

Description
This test checks the dynamic accuracy of the E5061A/E5062A. 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 E5061A/E5062A 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.
