Using the EXT SIG IN Signal (External Signal Source)
This makes the PBZ into a bipolar amplifier that amplifies the input signal that is applied to
EXT SIG IN (the BNC terminal). You can set the gain, the polarity (inverted or not inverted),
and the offset of the amplifier. Pressing the DC and AC keys that are used to set the internal
signal source will have no effect.
Input terminal specifications
Gain Setting
Configure the amplifier by specifying the gain using a value and the polarity (inverted or not
inverted) by specifying the sign (positive or negative). The absolute value of the specified
value is the gain. If the sign is positive, the polarity is not inverted. If the sign is negative, the
polarity is inverted.
