Mode ← AM settings
Selects the mode to derive the carrier signal for amplitude modulation.
"Normal"
Performs the standard amplitude modulation with a single sinusoidal
carrier signal.
"Scan"
(Option: R&S SMAB-K721)
Performs amplitude modulation with a higher dynamic range.
The R&S SMA100B provides a special exponential amplitude modu-
lation system optimized for highest dynamic range. You can use the
scan mode to emulate level behaviors of transmitter/receiver systems
with rotating antennas. Selecting "Mode > Scan" sets the modulation
type to "Exponential".
Note: Using exponential AM with an external source affects other
operating modes as described in "Interactions and characteristics"
on page 83.
Remote command:
[:SOURce<hw>]:AM:MODE on page 566
Type ← AM settings
Selects the type of the amplitude modulation for both paths.
Using exponential AM with an external source affects the coupling mode and the exter-
nal modulation input, see "Interactions and characteristics" on page 83.
"Linear"
Sets linear amplitude modulation with depths specified in per-
cent / volt.
"Exponential"
Sets ethe exponential AM type with depths in dB / volt.
