Control Fields for Analog Measurements

Scope To

This field selects the signal source for the oscilloscope. This allows you to bypass certain sections of the AF analyzer’s circuitry when viewing and measuring a signal. It also allows you to select measurement paths that include additional gain stages, improving the oscilloscope’s resolution when measuring low-level signals.

•Input looks at the unfiltered signal directly from the input.

•Filters looks at the signal after filtering through Filter 1 and Filter 2.

•De-Emplooks at the signal after filtering through Filter 1 and Filter 2, and after 750 ∝ s de-emphasis (if the De-emphasisfield is set to 750 us.)

•Notch looks at the signal after filtering through Filter 1 and Filter 2, after de-emphasis (if used), and after the notch filter.

AF ANALYZER

Sensitivity (RF analyzer)

RF analyzer sensitivity adds about 6 dB of sensitivity for the ANT IN port when High is selected and the Input Atten field is set to 0 dB.

Operating Considerations

Selecting High sensitivity may cause spectrum analyzer measurements to be uncalibrated when the ANT IN port is used (a message appears when this occurs).

High-level AM measurements may be distorted when high sensitivity is used with the ANT IN port.
