PROMAX-10
The CTB SHOWED parameter
allows
defining
the
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 and ∆FCS04 allow you to modify the
frequencies where the CSO is measured (the
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.
To exit the CHANEL-FREQUENCY CONFIGURATION menu, press the mode of
operation to which you want to access.
4.2.3.2
FREQUENCY Tuning
Pressing the CH-FR [10] key you
can switch between tuning by channel or
tuning by frequency and vice versa.
To verify you are working on the Frequency
Tuning mode, check what field is shaded:
-
If the channel is shaded, then you are
working in Channel Tuning Mode.
-
If the frequency is shaded, then you are working in Frequency Tuning
Mode.
In the frequency tuning mode, the instrument becomes a receiver with a
resolution of 10 kHz within the band from 5 to 863 MHz. In this mode you can tune any
signal within this band, including leakage pilots or telephone and communications
signals.
To change frequency, just press the rotary knob [9] until the digit you want to
change is underlined and then turn the rotary knob [9]. The channel name appears at
the left of the tuning frequency, as long as it corresponds to an active channel.
