Product description

The Tektronix PED line of high sensitivity and high bandwidth error detectors offer single and two-channel standalone configurations capable of BER measurement at data rates up to 40 Gb/s. The PED products support either PRBS or user-defined data patterns, with simple to use automatic or manual alignment of input clock and data, and pattern synchronization. The PED product makes an ideal companion for the Tektronix PPG pattern generator product family.

The PED line of error detectors are offered in two data input configurations:

  • The DC coupled input option can be used either as AC or DC coupled as long as the resulting input falls within the allowed voltage window of -0.6 to 0.2 V. A DC threshold output is provided and, when connected to the unused /data input, allows operation with single ended data input signals.
  • The AC coupled input option allows larger amplitude AC coupled inputs and has built-in differential and single ended programmable threshold adjustments.

Also, either half rate or full rate clock options are available.
