Stability
Spectral Purity
4-2 Characteristics
Drift
Because the analyzer frequency is corrected on retrace, drift occurs
only during the period of one sweep. This drift is in addition to
frequency reference error due to aging.
Frequency Span
> 100 kHz to 5 1 MHz
*After 1 hour warm-up at stabilized temperature.
Noise Sidebands
Refer to Figures 4-2 and 4-3 for typical noise sideband performance.
