USER'S MANUAL. PROMAX-10
DESCRIPTION
Audio modulation
Audio carrier offset
Digital channel bandwidth
( Only digital channels ) Frequency
where noise is measured in the C/N
measurement.
( Only digital channels )
measuring mode.
The parameters AUDIO FREQ., CHANNEL BW and NOISE FREQ. are
changed digit by digit, starting at the lowest weight.
To accede to the second page of the configuration menu, press CONFIG [14]
key again.
The CTB SHOWED parameter allows to define
the method of measurement for the CTB. IN CH (within
the channel) is the suitable method whenever the
carrier of the channel in study can be turned off. If it is
not possible, as approach, any other channel (free) can
be defined for the measurement of the CTB.
Parameters ∆FCS01, ∆FCS02, ∆FCS03
∆FCS04 allow to modify the frequencies where the CSO is measured (the
and
PROMAX-10 admits values from -0.5 to -2.50 and from 0.5 to 2.5 MHz). These
parameters are modified digit to digit, beginning by the one of smaller weight.
Finally, ∆FCH parameter allows to set the frequency offset for the channel
tuning ( PROMAX-10 admits values from 2.00 to –2.00 to MHz).
