About the VA-1842
1.1 Overview
The HDMI Protocol Analyzer VA-1842 (hereinafter referred to as the VA-1842 in this manual) enables the
protocol parts required in the development of HDMI transmitters to be checked. The HDMI video and audio can
be easily checked with the front LCD monitor and built-in speakers.
Furthermore, you can rewrite the performance information (EDID/SINK) of the VA-1842 unit so various kinds of
receivers (monitors) can be virtualized. The unit can thus be used in, for example, the development of devices
with HDMI terminals such as set-top boxes and DVD players.
In addition, the reception of sink device signals can also be checked by using the VA-1842 Generate function.
This manual collectively refers to devices with HDMI input terminals but without HDMI output terminals such as
monitors and TVs as receivers (monitors), and collectively refers to devices with both HDMI output terminals
and input terminals which perform output based on input signals as repeaters.
1.2 Features

ANALYZE (Measurement) Function
Measures the HDMI and DVI video timing.
Measures each packet content of HDMI.
Checks for differences from HDMI standard values.

Receiver (Monitor) Function
Enables HDMI input to be received.

Through Function
Enables checking the direct exchange of DDC/CEC of source devices and sink devices by allowing
VA-1842 input and output to pass through.

Generate Function
Enables receiving on the sink side to be checked using the timing and multiple patterns built into the
VA-1842. 3D timing can also be output.

Emulator Function
Enables the performance information of the VA-1842 unit to be changed to the performance of
various other monitors (e.g., high-definition TVs and NTSC compatible TVs).
