7.1.7 [PRA-BD12]: TEST MODE

With the S8602 (by setting the DIP switches), the SDI (NTSC/PAL) and AES/EBU signals for checking can be output from the
FPGA, using the built-in 27-MHz clock. During Test mode, an FFC-cable connection is not needed, because there is no need
A
to receive data from AVIB. (Check of FFC-cable connection is impossible.)
1. Setting for Test mode
Set Switch 1 of the S8602 to ON.
During Test mode, LED 1 (green) for checking operations flashes (repeatedly on and off for 1 second). The other LEDs
operate in the same way as in Normal operation mode.
2. Available SDI OUT signals
Video : NTSC: one color (gray)(Set Switch 2 of the S8602 to OFF.)
PAL : one color (gray)(Set Switch 2 of the S8602 to ON.)
Audio : Signal with frequency characteristics similar to those of a 1-kHz sine wave
B
3. Available AES/EBU OUT signals
Signal with frequency characteristics similar to those of a 1-kHz sine wave.
4. Waveform of the audio signal
The waveform of D/A-converted SDI and AES/EBU audio output signals is as shown below.
Although its frequency is 1 kHz, because of noise, it does not sound like a correct 1-kHz sound.
