Advantest D3186

The Advantest D3186 is a high performance pulse pattern generator to generate 7 types of pseudo-random (PRBS) patterns from 27-1 to 231-1, programmable (WORD) patterns up to 8M bits, or frame patterns of SDH or SONET structure at very high speed from 150 Mb/s to 12 Gb/s.

Moreover a system which is used to evaluate the bit error rate of super high speed optical communication devices and compound semiconductors, can be structured by combining D3186 with the D3286 error detector.

With the D3186 you have the option to have a built-in high precision synthesized clock generator. There are 16 types of frequency memories are provided for speedy frequency setting.

For PRBS patterns, mark ratio can be changed between 8 values. The type of payload can be selected from WORD, PRBS and CID for FRAME pattern.

ALTERNATE mode is available which changes over 2 patterns (WORD and FRAME) to execute measurement.

Various types of applications are available by using differential data output, differential clock output and fixed amplitude clock output.

Amplitude, offset and terminator conditions can be individually set for the differential data output and the differential clock output each. The terminator conditions can be selected from among TO 0V, TO -2 V or AC coupling.

From the motor drive type delay line, the phase of clock output can be changed in steps of 1 ps resolution up to ± 400 ps.

When error measurement is performed by using D3186 combined with D3286 Error Detector, the master slave function interlocks their patterns.

The GPIB feature enables full remote control, making it easy to construct a measurement and test system. The built-in floppy disk drive enables storing/calling the set conditions and the content of pattern setting.

Avoid using the D3186 in a dusty place or a place where the device is exposed to direct sunlight or where corrosive gas is generated. Always use the D3186 in a place where ambient temperature is 0 to 40 deg C, and relative humidity is 40% to 85%.

Applying too strong mechanical impact on the D3186 should be avoided. Because the D3186 has a cooling fan of discharge type, be sure to keep 10 cm or larger space between the rear panel and the wall. Also avoid blocking the air intake holes on both sides of the D3186.

Supply voltage shall be within 90 to 132 VAC or 198 to 250 VAC, 48 to 63 Hz. The 100 V and 200 V power circuits are automatically changed over. Because the device consumes maximum 550 VA power, use a power supply with sufficient capacity.
