Signal capture system and test apparatus including the same

A signal capture system comprising:

• a printed circuit board;
• a socket that is electrically connected to the printed circuit board;
• an interposer that is mounted on the printed circuit board;
• an external apparatus that is connected to the interposer, the external apparatus being configured to generate a control signal for controlling a reference memory component mounted on the socket, the control signal instructing the reference memory component to read a data signal stored according to an address signal, or store the data signal according to the address signal;
• and
• a separator that is connected between the interposer and a storage apparatus, the separator being configured to separate the address signal, the data signal, and the control signal according to a channel,
• wherein the interposer is configured to transmit the address signal and the data signal from the reference memory component to the storage apparatus, and transmit the control signal from the external apparatus to the storage apparatus,
• wherein a shape of the socket is defined according to a type of the reference memory component,
• wherein the separator includes,
• a signal information separator configured to separate a format, a level, and a timing of the address signal, the data signal, and the control signal;
• and
• a demultiplexer configured to separate inputs according to a channel along a selection line, wherein the inputs include the address signal, the data signal, and the control signal, and
• wherein the storage apparatus is configured to store the format, the level, the timing, the address signal, the data signal, and the control signal, which are separated according to the channel.

A test apparatus comprising:

• a signal capture system including a separator configured to receive and separate, according to a channel, first signals generated by a reference memory component and second signals generated by an external apparatus;
• and
• a storage apparatus that is connected to the separator, the storage apparatus being configured to store the first signals and the second signals separated according to a channel,
• wherein the first signals include an address signal and a data signal of the reference memory component,
• wherein the second signals include a control signal of the external apparatus,
• wherein the separator includes
• a signal information separator configured to separate a format, a level, and a timing of the address signal, the data signal, and the control signal;
• and
• a demultiplexer configured to separate inputs according to a channel along a selection line, wherein the inputs include the address signal, the data signal, and the control signal,
• wherein the storage apparatus is configured to store the format, the level, the timing, the address signal, the data signal, and the control signal, which are separated according to the channel.
