2. External Source
When "Ext" is selected, the RF signal generator receives the in-phase baseband
signal and quadrature phase modulating signal of I/Q modulation input from the
[I IN] and [Q IN] connectors (as shown in the figures below) at the rear panel
respectively.
Tip: When an external baseband signal is input and the baseband output is
turned "On", the instrument can output the I (In-Phase) components and Q
(Quadrature Phase) components of the I/Q modulation baseband signal
generated by the built-in baseband generator (wavetable) from the [I OUT]
and [Q OUT] connectors at the rear panel respectively.
Baseband Signal
1. Baseband Output
Press BaseBand  Switch to select "On" or "Off".
 On: turn on the baseband output function. The RF signal generator outputs
the I (In-Phase) and Q (Quadrature Phase) components of the I/Q
modulation baseband signal from the [I OUT] and [Q OUT] connectors at
the rear panel respectively.
 Off: turn off the baseband output function.
2. Baseband Level
Press BaseBand  Level to set the amplitude of the baseband output signal.
 Use the numeric keyboard to input the amplitude value and select the
desired unit from the pop-up unit menu.
 The amplitude units available are V, mV, uV, nV and dBm.
 You can press Backspace to delete the number at the left of the cursor.
 You can press the left/right arrow key to enter the parameter editing state
and move the cursor to the specified digit; then, rotate the knob to modify
the parameter value.
 You can also rotate knob to modify the amplitude at the current step.
 You can press Step to set the step.
