14 Typical VSWR performance: performance expected to be met in 95 % of the cases with a confidence level of 95 %, temperature +20 °C to +30 °C,
input set to “DC coupling”. These values are not warranted and are subject to modification if a significant change in the statistical behavior of
production instruments is observed.
15 Mechanical RF attenuator: 5 dB steps. Electronic IF attenuator: 1 dB steps.
