Prepare test report for this item using receiver system indications for system codes: U04, U06, U10, U11, Ul2, U14, F00
and W05.
3 Not checked below -100 dB.
4 Accuracy of measuring receiver must be considered as well as losses associated with any adapter used.
5 Some attenuation settings (>30 dB) will result in accuracy ratios between standard and TI to be <4:1.
6 This is a flatness specification. The maximum recorded attenuation value minus the minimum recorded attenuation value
for each setting will be less than or equal to this accuracy.
7 Deviation from value measured at 4 GHz.
8 Insertion loss for serial number 2524A44630 and below is (0+0.11+1.39 (frequency in GHz). Insertion loss for serial
number 2524A44630 and above is (0+0.2 + 2.3 (frequency in GHz).
