Abstract
Provided is an output apparatus that outputs an output signal corresponding to an input signal, comprising a plurality of drivers that each output an intermediate signal having a waveform corresponding to the input signal; an adding section that adds together the intermediate signals output from the drivers and outputs the result as the output signal; and a control section that controls a difference in delay amount, which is from when the input signal begins to change to when the intermediate signal begins to change, among the drivers according to a designated slew rate.

An output apparatus that outputs an output signal corresponding to an input signal, comprising:
- a plurality of drivers that each output an intermediate signal having a waveform corresponding to the input signal;
- an adding section that adds together the intermediate signals output from the drivers and outputs the result as the output signal;
- and
- a control section that controls a difference in delay amount, which is from when the input signal begins to change to when the intermediate signal begins to change, among the drivers according to a designated slew rate.
An output apparatus that outputs an output signal corresponding to an input signal, comprising:
- a driver that outputs an intermediate signal having a waveform corresponding to the input signal;
- a correction driver that outputs a correction signal having a waveform corresponding to the input signal;
- a high-pass filter that passes a high-frequency component of the correction signal output from the correction driver;
- an adding section that adds together the intermediate signal output from the driver and the correction signal passed through the high-pass filter, and outputs the result as the output signal;
- and
- a control section that sets a voltage level of the correction signal output from the correction driver, according to a designated slew rate.
A test apparatus that tests a device under test, comprising an output apparatus that supplies the device under test with a test signal, wherein the output apparatus includes:
- a plurality of drivers that each output an intermediate signal having a waveform corresponding to an input signal;
- an adding section that adds together the intermediate signals output from the drivers and outputs the result as the test signal;
- and
- a control section that sets a difference in delay amount, which is from when the input signal begins to change to when the intermediate signal begins to change, among the drivers according to a designated slew rate.
A test apparatus that tests a device under test, comprising an output apparatus that supplies the device under test with a test signal, wherein the output apparatus includes:
- a driver that outputs an intermediate signal having a waveform corresponding to an input signal;
- a correction driver that outputs a correction signal having a waveform corresponding to the input signal;
- a high-pass filter that passes a high-frequency component of the correction signal output from the correction driver;
- an adding section that adds together the intermediate signal output from the driver and the correction signal passed through the high-pass filter, and outputs the result as the test signal;
- and
- a control section that sets a voltage level of the correction signal output from the correction driver, according to a designated slew rate.
