MODE

• Noise Cancel
This function is used to reduce the noise level for any
possible small signals. It is only available in FM IBOC
submenu, when
Mask Type
is set to
NRSC-5-B
<Hybird>
.
Channel
Key access:
[MODE] > {IBOC Measurement} > {AM}/{FM}
> {Channel}
Press the
Channel
softkey to access a channel list menu
with customized channel setting files. The channel file is
easy to reload, delete and copy as needed. The channel
list function helps you more quickly set up their
instruments and complete the measurements.
Auto Tune
Key access:
[MODE] > {IBOC Measurement} > {AM}/{FM}
> {Auto Tune}
Press this softkey to automatically find out the largest
signal over specific broadcasting frequency band. e
measure its carrier frequency more accurate and
measure its unmodulated carrier power or nominal
power spectral density in a 1 kHz bandwidth of the
digital Primary Main sidebands for All Digital IBOC (FM)
case. These two parameters will be adopted as 0 Hz
offset of mask from carrier frequency and 0 dBc level
relative to unmodulated carrier or nominal power
spectral density in a 1 kHz bandwidth of the digital
Primary Main sidebands for All Digital IBOC (FM) case.
The reference level estimation method is different
between IBOC (FM) all digital mode and other modes.
This function is correlative to Mask Type selection.
