Agilent 8753ES System Verification and Performance Tests
Required Equipment
NOTE The HP/Agilent 8496A step attenuator (Option H19) comes with a special
calibration that supports the measurement uncertainties expressed in the
test record for this performance test.
The special calibration consists of two measurements. The first is a
measurement of the attenuation at each step. The data reported for this
measurement have the following uncertainties:
• ±0.006 dB from 0 to 40 dB
• ±0.015 dB from >40 to 80 dB
• ±0.025 dB from >80 to 90 dB
• ±0.05 dB >90 dB
The second calibration measurement characterizes match stability between
attenuator settings for each attenuator port. The vector difference of S
11
or
(S
22
) between the reference attenuation step and all the other steps is
measured. The magnitude of this difference is certified to be <0.0316
(>30 dB).
