3.5.4 DC bias addition
This product can add a DC voltage onto an output voltage signal for output.
For this setting, set the bias switch (BIAS) to ON and use the bias dial. A bias voltage beyond
±
75 V.
An added voltage can be monitored on the output LED meter, if the input level is zero.
The relationship between a dial scale mark and output bias voltage can be calculated as indicated below.
The polarity of a DC bias is not switched by the output polarity switch (INVT).
Bias output voltage = (Set scale mark

5.00)

17.5 Vdc
Note that the bias on/off state is not switched even if the bias switch (BIAS) is pressed again before 1
second elapses after switching the bias on/off state. To switch the bias on/off state in succession, insert a
pause of at least 1 second.
The overload LED (OVLD) is turned on, if an output voltage exceeds the output voltage range.
When adding a DC bias, ensure that the waveform does not clip.
Note: This function is for adding DC voltage to the output signal. Do not use this function when
making fine adjustment to set the offset voltage included in the output signal to zero.
3.5.5 Output polarity switching
The output polarity can be set to be in-phase or reversed-phase by using the output polarity switch (INVT)
on the front panel.
The LED on the output polarity switch (INVT) is turned on when the output polarity is in reversed phase.
Note that the output polarity is not switched, even if the output polarity switch (INVT) is pressed again
before 1 second elapses after switching the output polarity. Insert a pause of at least 1 second to switch the
output polarity in succession.
