Storage Device Design and Measurement

Signal Generation Solutions

The AWG710 arbitrary waveform generator delivers the industry's fastest mixed-signal solution at 2.0 GHz (4.0 Gb/s) to characterize read/write devices with pre-compensated read/write (NLTS) signals.

The DTG5000 Series data timing generator provides multi-channel, high-speed patterns for optical write channel strategies up to 3.35 Gb/s and up to 16 channels with independent level and timing control for the ultimate in performance and versatility.

Both signal sources preserve the signal fidelity of read/write channel signals to minimize the effects of mechanical and physical media noise common to both magnetic and optical storage devices. Each also reliably reproduces red and blue-ray laser diode driver signals to reduce laser burn unique to optical storage devices.

Analog/Mixed Signal Sources

• Up to 2.0 GHz (4.0 Gb/s) write channel capability with simultaneous high-speed analog and digital output - 1 complementary analog channel and 2 complementary programmable markers - for magnetic and optical storage design
• Up to 2.0 GHz, < 175 ps rise time PRML NLTS read channel signals with colored noise for magnetic storage design
• Simulate Serial-ATA and SCSI signals
• Playback pre-recorded track/sector signals acquired by a Tektronix oscilloscope

Logic Signal Sources

• Up to 3.35 Gb/s write channel strategy and up to 16 channel outputs with independent fine timing control (0.2 ps resolution) for optical storage design
• 32 Mbit pattern length
• ASCII file import of pattern data over built-in LAN, CD-ROM, USB memory device
• Replicate Intersymbol Interference effects with different data patterns for magnetic and optical storage design
