5. D/A out (CON3) and full-scale adjustment (VR2)

The output waveforms of the D/A converter are output from CON3. When an oscilloscope or other such

instrument is used for monitoring, a 50Ω terminating resistor is required. The full-scale output voltage must

also be adjusted. And the output amplitude should also be adjusted to 1Vp-p by the VR2.

6. SW1 setting

These are the switches for PS, ENABLE, MINV, and LINV of the A/D converter and the DAINV of the D/A

converter. Normally all are used ON.

7. S2 setting

This is the selection of the frequency division ratio for the clock which is supplied to the D/A converter.

Normally, 1/1 is used but the ratios from 1/2 to 1/16 are also used for the envelope test or other tests.
