Specifications for Frequency and Power Characteristics
1. Parentheses denote typical performance.
2. Refer to frequency bands on page 12 for N values.
3. Harmonic performance outside the operating range of the instrument is typical.
4. Spurs outside the operating range of the instrument are not specified.
5. Specifications apply for FM deviations < 100 kHz and are not valid on FM. For non-constant amplitude formats, unspecified spur levels occur up to the
second harmonic of the baseband rate.
6. Specifications apply for CW mode only.
7. Calculated from phase noise performance in CW mode only at -2.5 dBm for standard instruments, -0.5 dBm with Option 506, and +2.5 dBm with Option UNB.
8. For other frequencies, data rates, or bandwidths, please contact your sales representative.
