Distortion 0.2% or less (no load when 100 kHz or less, BW500 kHz, and
3 Vrms output)
ALC PORT1 / PORT2 / OFF
The range that can be controlled constantly will be narrower than
the setting range of the measurement signal amplitude depending
on product variations or DUT impedance.
Output limit
Setting range 1 aVrms to 999 GVrms
Setting resolution 3 digits or 1 aVrms, whichever is the largest
Remark This function prevents an excessive signal level being output due
to an incorrect setting. A measurement signal amplitude exceeding
the output limit setting cannot be output.
・
Normal DC bias
Setting range −999 GV to +999 GV
However, the setting range is limited to −5.00 × K V to +5.00 × K V
by DUT drive amplifier gain setting K.
There is a following restriction between the measurement signal
amplitude setting and normal DC bias setting.
(Measurement signal amplitude setting [Vrms] × 1.42) + |Normal DC bias
setting [V]| ≤ 5.0×|K|

DUT drive amplifier gain setting K
Set the gain of the amplifier or attenuator that supplies the
measurement signal to the DUT.
The measurement signal amplitude and normal DC bias applied to
the DUT can be set directly.
Setting range ±(1E−12 to 1E+12)
Setting resolution 3 digits or 1E−12, whichever is the largest
