Performance Tests

12. Receiver Magnitude Dynamic Accuracy

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

) 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).
