Fields
Notch Freq
This field sets the center frequency for the variable frequency notch filter. It is
typically used for distortion and SINAD measurements at frequencies below or
above the standard 1 kHz notch filter.
This field is not displayed if your Test Set does not have this feature.
Operating Considerations
When the Notch Coupl field on the CONFIGURE screen is set to AFGen1, this
filter and the
AFGen1 Freq field match their settings. A warning message is then
displayed if you attempt to set the
AFGen1 Freq value outside the 300 Hz to 10
kHz range of this filter. When the
Notch Coupl field is set to None, this filter
and
AFGen1 Freq operate independently.

Notch Gain
This field displays and selects the gain of the AF Analyzer’s notch filter amplifier.
This amplifier is only used for making SINAD and distortion measurements.
(Refer to the
"Gain Cntl" field on page 268.)
