Functional Description

• Differential offset
The specified offset voltage is added to the I and Q waveforms. An offset voltage that
is negative to I and Q is added to I
_
and Q
_
. Differential offset cannot be specified on
models with single-ended outputs.

Low-pass Filter «For procedures, see section 5.4»
For each output terminal set (OUT), you can select a low-pass filter for removing
unneeded high-frequency components that are generated when waveforms are output.
Noise «For procedures, see section 5.4»
You can add AWGN (Additive White Gaussian Noise) to the output waveform on each
output terminal set. Because the AWGN is added as a digital signal before the D/A
converter (DAC, see the block diagram in section 2.2) stage, it is also applied to the
signal output from the digital output terminal.
Output Shift «For procedures, see section 5.5»
For each output terminal set (OUT), you can shift the output start point ahead on the
waveform.
Shift time = Set point

(1/clock frequency)
Analog/Digital Output «For procedures, see section 5.6»
For each output terminal set (OUT), you can select whether to output analog signals
from the output terminal set (OUT) on the front panel or 14-bit digital signals of the
waveform data from the digital output terminal on the rear panel. If you select digital
signal output, you can also select the signal output format.
