General description of the
used ANRITSU MP1764A
for sale.
The Anritsu MP1764A Error Detector is used in combination with the MP1763B Pulse Pattern Generator to detect errors used to evaluate conformity with ITU-T standards. In addition, complicated searching for input thresholds or phase adjustments is simplified with the touch of a single key. These functions are ideally suited for the research and development of ultrahigh-speed logic ICs and digital communication systems.
Specifications
Operation frequency: 0.05 to 12.5 GHz.
Data input
Input waveform: NRZ.
Input voltage: 0.25 to 2.0 Vp-p.
Threshold voltage variable range: -3.000 to + 1.875 Vp-p (1 mV steps).
Phase margin: >=70 ps (typical value at 10 Gb/s, PRSS 2^23 - 1, and an input amplitude of 1 Vp-p.
Input sensitivity: 50 mVp-p (typical value at 10 Gb/s and PRBS 2^23 - 1.
Clock input
Input waveform: Rectangular wave «0.5 GHz), rectangular or sine wave (>=0.5 GHz), duty factor, 50%.
Input voltage: 0.25 to 2.0 Vp-p.
Input delay variable range: -500 to +500 ps (1 ps steps).
Receive Pattern
Pseudorandom binary sequence pattern (PRBS);
Pattern: 2^n-1 (n: 7, 9, 11 , 15, 20, 23, 31),
Mark ratio: 1/2, 1/4, 1/8, 0/8 (1/2, 3/4, 7/8, 8/8 are possible with logic inversion).
Number of AND bit shift when setting mark ratio: 1, 3 bits (selectable by using DIP switch on rear panel).
Tracking: Information of pattern set by the error detector is sent to the pulse pattern generator via GPIB.
