Pulse modulationWarning: 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:• No attenuator is fitted (R&S ® SMA-B103L/-B106L frequency option)• in HIGH POWER mode• in AUTO mode if the level is in the high power range, i.e. the mechanical relay bypass is switchedOtherwise, the level is decreased by 30 dB during sample & hold measurementOperating modesOn/off ratioRise/fall timePulse repetition frequencyVideo crosstalkexternal, internal>80 dB, typ. 100 dBf > 180 MHz10 %/90 % of RF amplitude 20 ns, typ. 10 ns0 Hz to 10 MHzspectral line of fundamental of 100 kHz 100 kΩ1 Vthreshold 0.8 V>10 kΩ or 50 ΩselectableWith option R&S ® SMA-B20/-B22 (FM/ϕM)Modulation input FM/φM EXTinput impedanceinput sensitivity (peak value for setmodulation depth or deviation)>100 kΩ or 50 Ω1 V12 R&S ® SMA100A Signal Generator Version 02.02, August 2007
