Advantest D3186 High Performance Pulse Code Pattern Generator

Description:

The Advantest D3186 is a high-performance pulse pattern generator that generates seven types of pseudo-random (PRBS) patterns from 27-1 to 231-1. programmable (WORD) patterns.

Programmable (WORD) patterns, up to 8M bits, or frame patterns for SDH or SONET structures, at speeds ranging from 150 Mb/s to 12 Gb/s.

In addition, by combining the D3186 with the D3286 BER detector, it is possible to build a system for evaluating the BER of ultra-high-speed optical communication devices and compound semiconductors.

With the D3186. you can choose a built-in high-precision synthesized clock generator. Sixteen types of frequency memories are provided for fast frequency setting.

For PRBS mode, the marker ratio can be changed between 8 values. Payload type can be selected from WORD, PRBS and CID for FRAME mode.

ALTERNATE mode is available and can be switched on 2 modes (WORD and FRAME) to perform measurements.

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 set for differential data output and differential clock output, respectively. The terminator condition can be selected from TO 0 V, TO -2 V, or AC coupling.

Starting from a motor-driven delay block, the phase of the clock output can be varied in 1 ps resolution steps up to ± 400 ps.

When using the D3186 in combination with the D3286 error detector for error measurement, the master-slave function interlocks their modes.

GPIB functionality allows full remote control, making it easy to build measurement and test systems. The built-in floppy disk drive can store/recall the contents of set conditions and mode settings.

Avoid using the D3186 in dusty areas or where the unit is exposed to direct sunlight or where corrosive gases are generated.Always use the D3186 in an area with an ambient temperature of 0 to 40 degrees Celsius and a relative humidity of 40% to 85%.

Avoid excessive mechanical shock to the D3186. Since the D3186 has an exhaust cooling fan, be sure to leave a space of 10 centimeters or more between the rear panel and the wall. Also avoid blocking the air inlet holes on both sides of the D3186.

Supply voltage should be 90 to 132 VAC or 198 to 250 VAC, 48 to 63 Hz. 100 V and 200 V power circuits switch automatically. Use a power supply with sufficient capacity since the unit consumes a maximum of 550 VA.
