3.1.8 Modulation Mode
The modulation mode can be selected by ac>
tuating the modulation mode keys (R&S
EK!896) or, once the modulation mode menu
has been called up, by softkey actuation. The
currently effective modulation mode is indi>
cated in the modulation mode field.
The following modulation modes are avail>
able:
f AM (A3E, amplitude modulation)
f CW (A1A, Morse telegraphy)
f USB (J3E, upper sideband)
f LSB (>J3E, lower sideband)
f FAX1 (F1C, facsimile)
f FSK (F1B, TTY)
f AFSK (F1B, TTY)
f F7B (diplex telegraphy)
f FAX2 (F3C, facsimile)
f FM (F3E, frequency modulation)
f ISBLSB (B8E, monitoring sideband,
lower sideband)
f ISBUSB (B8E, monitoring sideband,
upper sideband)
If the default value setting is activated, altering
the modulation mode automatically sets the
appropriate values for bandwidth, BFO fre>
quency, type and time of control, frequency
deviation and offset, baud rate, signal polarity
and demodulation.
