Bandwidth |
This is the required bandwidth of the transmitter. The above example represents "16.0kHz bandwidth". The decimal point is replaced with "H", "K", "M", or "G". These define as: |
H |
= Hertz |
K |
= Kilohertz |
M |
= Megahertz |
G |
= Gigahertz |
|
1st Digit |
A |
= AM (Amplitude Modulation), double-sideband |
B |
= AM, independent sidebands |
C |
= AM, vestigial sideband |
D |
= Amplitude and Angle Modulated carrier |
F |
= Angle Modulated, frequency modulation |
G |
= Angle Modulated, phase modulation |
H |
= AM, single-sideband, full carrier |
J |
= AM, single-sideband, suppressed carrier |
K |
= Pulse, amplitude modulation (PAM, PSM) |
L |
= Pulse, width modulation (PWM) |
M |
= Pulse, phase or position modulation (PPM) |
N |
= Emission of an unmodulated carrier |
P |
= Pulse, no modulation |
Q |
= Pulse, carrier also angle-modulated during pulse |
R |
= AM, single-sideband, reduced or variable level carrier |
W |
= Pulse, two or more modes used |
X |
= All cases not covered above |
|
2nd Digit |
0 |
