Frequency Characteristics

These are not specifications. Characteristics provide useful but nonwarranted information about instrument performance.

Stability

Drift

Drift* (Option 013)

175 kHz/5 minutes after 2 hour warmup and 5 minutes after setting center frequency

Frequency Span 5 10 MHz, Free Run ~2 kHz/minute of sweep time

’ (Option 013)

Because the analyzer is locked at the center frequency before each sweep, drift occurs only during the

:ime of one sweep. For Line, Video or External trigger, additional drift occurs while waiting for the appropriate rigger signal.

Resolution Handwidth (-3 dB)

Range

Shape

1 kHz to 3 MHz, selectable in 1, 3 and 10 increments, accuracy f20% and 5 MHz. Resolution bandwidths may be selected manually, or coupled to frequency span.

Synchronously tuned four poles. Approximately Gaussian shape.
