Harmonics (measured)
1. Specifications are typical for harmonics beyond specified frequency range (beyond 50 GHz for Option 567).
2. Specification applies to units with serial numbers ending with 45130000 or greater. For units with lower serial numbers, the specification is –28 dBc.
3. Typical below 250 MHz if Option 1EH is installed and the filters are off.
4. In ramp sweep mode (Option 007), harmonics are –30 dBc below 250 MHz.
