1. Maximum CW power specifications are warranted from 15 to 40 ˚C. Maximum power in the 40 to 50 ˚C temperature range typically degrades less than 1 dB.
2. Instrument specifications are based on max specified power, unless otherwise stated. When operating at max available power, spectral purity will be
degraded.

1. CW power accuracy specifications are warranted from 0 to 50 ˚C. Specifications apply within ± 3 ˚C of last power alignment. Temperature compensation is
ON. If temp comp is OFF, amplitude drift will be ≤ 0.2 dB/˚C. For instruments with Option 1ED Type–N connectors, specifications apply below 18 GHz and
performance is typically degraded 0.2 dB above 18 GHz.
2. Specifications apply in vector mode only, over a power range of –5 to –85 dBm.
