1. Measured using a CW signal with power set to –10 dBm. Performance is unspecified for non–harmonics beyond the specified frequency range. Non–
harmonic specifications are warranted from 15 to 40 ˚C.
2. For large offsets > 4 GHz, broadband noise will drop.
3. CW signal measured with power set to +4 dBm.
4. CW signal Measured with power set to +5 dBm.
5. Does not apply to N5192A UXG vector adapter, modified version.
