Details

TPA-MP-4R is used with a Quantum Data 882 in four separate applications.

These are as follows:
  • Application 1 - Provides Eye measurement, EDID emulation, Vcc Power & Hot Plug support while measuring waveforms with an oscilloscope during HDMI physical layer compliance tests.
  • Application 2- Serves as a CEC bridge for testing Sink devices during CEC compliance testing. The TPA-MP-4R can be used instead of the TPA-CEC-4R.
  • Application 3 - Serves as a CEC bridge for testing Source devices during CEC compliance testing. The TPA-MP-4R can be used instead of the TPA-CEC-4R.
  • Application 4 - Serves as a passive monitoring device for the DDC, hot plug and 5V leads. The TPA-MP-4R can be used instead of the TPA-ACA-3R.

Applications

Application 1 - Eye Measurement, EDID emulation, AVCC Power & Hot Plug Support

Using Tektronix Test Instruments
The 882CA provides EDID emulation and DDC, EDID, hot plug and CEC transaction monitoring. The TPA-MP-4R provides +3.3Vcc via the P40 2-wire cable. The TPA-MP-4R connects the 882CA HDMI Rx 1 to the Tek TPA-P-DI via P30 8-wire cable. TPA-P-DI connects Rx DDC, Hot Plug Detect and CEC to the source device under test. The following illustration depicts these connections.

Note: Optional cable kit provides the 2x 30-00157, 1x 30-00158 and 1x 30-00159 cables shown above. Agilent users additionally need to source a separate cable, N1080A H01, EFF-AGI-TPA-P Rev A from Agilent.

Using Agilent Test Instruments
The 882CA provides EDID emulation and DDC, EDID, hot plug and CEC transaction monitoring. The TPA-MP-4R provides +3.3Vcc via the Pomona 5069 8-wire cable. The TPA-MP-4R connects the 882CA HDMI Rx 1 to the Agilent TPA-P via 5069 8-wire cable. TPA-P connects Rx DDC, Hot Plug Detect and CEC to the source device under test. The following illustration depicts these connections.

Application 4 - Passive monitoring
The Auxiliary Channel Analyzer (ACA) can monitor DDC, EDID, hot plug transactions between a device under test and one of the 882's own internal HDMI ports in the emulation mode. The new TPA-MP-4R as well as the TPA-ACA-3R test point adapter allows the ACA to passively monitor DDC, EDID, hot plug transactions between the HDMI ports of two devices under test e.g. a set top box and an HDTV. The diagram below depicts how to connect the devices under test and the 882 to passively monitor transactions between two devices under test.
