1. For 23 °C ±5 °C. Accuracy degrades by 0.02 dB/°C over the full temperature range and by 0.3 dB above +7 dBm (degraded by 0.5 dB above +10 dBm with Option UNB).
Level accuracy specification maintained only with return to calibration.
2. The reverse power protection circuitry triggers at nominally 1 watt.
3. Parentheses denote typical performance.
4. Refer to frequency bands on page 4 to compute specifications.
5. Performance is typical for spurs at frequencies above the maximum operating frequency of the instrument. Performance typically is –60 dBc between 225 and 249.999 MHz.
6. Specifications apply for FM deviations <100 kHz and are not valid for FM.
For non-constant amplitude digital formats, unspecified spur levels occur up to the second harmonic of the baseband rates.
7. Specifications apply for CW mode only.
