Actual DCS Deviation(Narrow):0.35[kHz]
- [6] LTR Deviation
This parameter is used to align the LTR deviation.
Press [Enter] on "[6] LTR Deviation " to align LTR Deviation.
Select the Channel 1 in alignment range.
Press the [Space] key on the keyboard to activate the transmitter, and injects a LTR
test tone.
Press the [UP]/[DWN] key, as need, to set the LTR Deviation (Wide) to the following
specification.
Press [Enter] to lock in the new data.
Select the Channel 2, and set the LTR deviation (Narrow), same as Channel 1.
LTR Deviation(Wide) :0.80[kHz](
±
0.1[kHz])
LTR Deviation(Narrow) :0.60[kHz](
±
0.1[kHz])
The actual LTR deviation will increase around 20% based on the above alignment as
follows,
Actual LTR Deviation(Wide) :1.00[kHz]
Actual LTR Deviation(Narrow):0.70[kHz]
