4.2 Increasing of Output Voltage by Balanced Output
HSA42011 4-4
4.2 Increasing of Output Voltage by Balanced Output
The maximum output voltage can be doubled by using two product units. The maximum output current
remains unchanged from the current output when one unit is used. Be sure to use the same type of
high-speed bipolar amplifier.
As shown in "
Figure 4-3 Connection of Two Units
", divide the output of a signal generator with a
T-type adapter for connection to the input connector (A or B) of each unit.
Set the output polarity switch (INVT) on one unit to INVT so that the output phase is opposite to that of
the other unit. Set the input impedance to 10 k

on both units. Set the same gain on both units.
Connect a load between the outputs of the two units as shown in " Figure 4-3 Connection of Two
Units
". At this time, the connection terminal of a load cannot be connected to
the chassis of
this product
or the signal generator. When a load is used in this mode of connection, the load must therefore be isolated
from the ground potential and signal source.
Note that the polarity of the bias remains unchanged even when reversed phase (INVT).
The frequency characteristic, maximum output voltage, and maximum output current may be degraded
than the specifications.

The connection terminal of a load cannot be connected to the chassis of this product or the signal
generator.

heck the output voltage with a high voltage differential probe.
●
Near the maximum output voltage and maximum output current, the balance between the two units
may be lost and the operation may become unstable, resulting in damage to the load.
