Spectral purity
1.
Specifications for harmonics beyond maximum instrument frequencies are typical.
2.
Specifications for sub-harmonics beyond maximum instrument frequencies are typical.
3.
Performance is typical for spurs at frequencies above the maximum operating frequency of the instrument.
Specifications apply for CW mode only. Performance typically is –60 dBc between 200 and 250 MHz.
4.
For instruments with serial number prefixes below MY4330 or US4330, the specification is –136 dBc/Hz.
