Level
The R&S SMA100A has three different modes for level setting:
NORMAL mode: In this mode, the attenuator switches without wear and tear due to the exclusive use of electronic switches. The
maximum specified level depends on the set frequency (see table below). A typical level overrange up to +20 dBm is available.
HIGH POWER mode: In this mode, the electronic attenuator is bypassed with mechanical relays for high output power (up to
typ. 28 dBm overrange). The relays are not switched over in this mode. The typical minimum level is –11 dBm.
AUTO mode: In this mode, the mechanical relay bypass is switched automatically if the set level is higher than the specified max.
level in the mode NORMAL. The output level is specified over the full range from –120 dBm up to +18 dBm (+15 dBm for
R&S SMA-B106).
The R&S SMA100A is also available without attenuator (option R&S SMA-B103L and R&S SMA-B106L).

Pulse modulation
Warning: When pulse modulation is activated, the ALC state of the R&S SMA100A is automatically changed to ALC OFF
(sample&hold). In this state the ALC loop is opened and the output level is not regulated but the level modulator is set directly. In order
to set the correct output level a sample&hold measurement is executed after each frequency or level setting.
In the following cases the nominal ON level is present for typ. 3 ms to 5 ms after level or frequency setting:
a) No attenuator is fitted (frequency option R&S SMA-B103L/-B106L)
b) in HIGH POWER mode
c) in AUTO mode if the level is in the High Power range, i.e. the mechanical relay bypass is switched
Otherwise, the level is decreased by 30 dB during sample&hold measurement
