All CD/DVD writing quality tests are done using the IQB Omni CD DVD Analyzer by Quantized. The IQB Omni from Quantized Systems is a physical disc analyzer, covering all CD and DVD formats, designed to meet the Quality Control demands of the duplication and replication sectors.

Omni's features allows you to identify media quality issues and highlight drive performance and recording problems.

The system is based on a Philips CD/DVD drive. It supports the majority of the optical disc formats, including CD-ROM, CD-R/RW, CD-A
DVD-R/-RW, DVD-R DL, DVD+R/+RW, DVD+R DL, DVD-ROM 5 and DVD-ROM.

The platform can test the media for the following signals:

CD-R/CD-ROM/CD-A	DVD+R/+RW	DVD-R/-RW	DVD-ROM
Reflectivity	R-I14H	R-I14H	R-I14H
Jitter	Modulation	Modulation	Modulation
I11/ITop	Jitter	Jitter	Jitter
Asymmetry/Beta	PI Sum 8	PI Sum 8	PI SUm 8
BLER	PI Unc	PI Unc	PI Unc
E11 to E32 Error Statistics	POF	POF	POF
Burst Errors	Beta	Beta	Asymmetry
	ADER		EDC
	ADER Unc

Test speeds for CD media are set at 16X and for DVD media at 4X.

The equipment is capable of providing measurements on the complete data area or at specific positions defined by the user (Quick Test mode). This zone testing procedure allows multiple areas of the disc to be tested in a single operation.

All numerical and graphical data are stored in a database. Data can be recalled with user defined criteria to create sets of related key results. Data can also be imported into most common software packages - MS Excel etc.
