The CTB SHOWED parameter allows defining
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 and ∆FCS04 allow modifying the
frequencies where the CSO is measured (the
-2.50 MHz to 2.5 MHz).
The options available on the Configuration menu in the DIGITAL measurement
mode are next:
Freq. Mode: It allows you to change the
measurement signal among ANL
(Analogue), DIG (digital) and LEV
(Power Level).
Freq. Step: It allows you to change the step of
frequency. This is put into
practice when you are using the rotary knob to change frequency.
Channel BW: It allows you to change the channel bandwidth.
Noise Freq.: It allows you to change the noise frequency.
Noise mode: In this mode there are three options: AF (frequency offset), BW/2
(half the bandwidth), FREQ (noise frequency).
