6.3.3.1 Signal Direction
Access VNC : [s] > "F1"
Signal Direction
Defines the reference for phase notation (see Chapter 6.3.1.3, "Phase Notation in VOR
Measurements" , on page 71).
"From" North direction at the VOR beacon
"To" North direction at the receiver/ aircraft
Remote command:
SETUP:UNIT:VORDIRECTION
on page 188
6.3.3.2 Channel Frequency Configuration (CH FREQ)
Access VNC : [q]
The channel frequency determines the nominal frequency at which the measurement is
performed. For some avionics standards, the channels are associated with specific fre-
quencies. (See
Chapter A, "ILS Channel Frequency List" , on page 275 and Chapter B,
"VOR Channel Frequency List" , on page 277.)

CH
Sets the receiver frequency channel on the active receiver board according to the
ICAO frequency list.
Remote command:
RFCH
on page 183
Freq
Sets the nominal frequency for the measurement. By default, this frequency is also
assumed to be the center frequency for spectrum displays, unless an offset is defined.
For measurements on two frequencies, the frequencies are defined as offsets to this
nominal frequency.
Remote command:
RF
on page 183
Step Size
Defines the frequency step size for the rotary knob when setting the frequency.
