. The noise level of the
output waveform in the Wave View list is set to the specified value.
Explanation
You can set the gain, phase, IQ gain ratio, quadrature offset, voltage offset, low-pass filter,
and other parameters of the output waveform for each output terminal set (OUT1 to 4).
Gain
You can set the amplitude of the output waveform. In addition, the RMS and peak
values corresponding to the specified gain value are assigned. If phase, IQ gain ratio,
and quadrature offset are not specified, 2 Vp-p is set to 0 dB.
Selectable range: –20.0 to –6.0 dBm (in 0.1 dB steps)
Default value: 0.0 dB
Phase
You can set the rotation angle (amount of phase shift) on the IQ plane of the output
waveform.
Selectable range: –180.0 to 180.0 deg (in 0.5 deg steps)
Default value: 0.0 deg
IQ Gain Ratio
You can set the amplitude difference X of the output waveforms as a percentage of the
amplitude of Q. Amplitude X is set in the opposite direction to the amplitude of the I and
Q waveforms. As I is increased Q decreases and vice versa.
Selectable range: –30.0 to 30.0% (in 0.5% steps)
Default value: 0.0%

Quadrature Offset
You can set the angles of the I and Q axes of the output waveform. If the phase is
specified, the specified angle with respect to that phase position is applied.
Selectable range: –30.0 to 30.0 deg (in 0.5 deg steps)
Default value: 0.0 deg
