NOTE The 8496A step attenuator (Option 003, H18) 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 S11 or S22 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).
