SMIQExternal Modulation Source AMIQ(LEVEL) BIAS DC offset in I/Q channel for the BALANCED setting.The indicated level remains the same with the I/Qoutput (LEVEL I/Q = OFF) turned off, provided theoutput impedance was prior set to 50 9 with thecommand OUTPUT OFF IMPEDANCE.If the output impedance is set to HIGH with the I/Qoutput off, the output connector is isolated with arelay and the BIAS setting has no effect.(Only with option AMIQ-B2).MARKER...Opens a window to configure the four binary marker outputs of AMIQ (eg tocontrol power ramping of SMIQ), see AMIQ operating manual, section MarkerOutputs.FREQ 100. 000 000 0 MHz LEVEL - 30.0 dBmFREQUENCYLEVELANALOG MODVECTOR MODDIGITAL MODDIGITAL STDAMIQ CTRLLF OUTPUTSWEEPLISTMEM SEQSETUP...
