3.1 Calibration Setup

Figure 3-1 below shows the recommended calibration setup. This setup uses the CA-210 color analyzer by Konica Minolta and the Cheetah SPI adapter by Total Phase. The key points to note are:

  • The probe of the CA-210 should be pointed at the diffuser screen illuminated by the DLP3030-Q1 based PGU
  • There is room for Neutral Density (ND) filters to be inserted in between the diffuser screen and the CA-210 probe
  • The PC is connected to the DLP3030-Q1 based PGU using a Cheetah SPI adapter
  • The PC is also connected to the CA-210

Note: ND filters are needed because the CA-210 likely cannot measure the entire brightness range of the PGU. ND filters are necessary when the DLP3030-Q1 PGU output is too bright.
