Tektronix SD42 Optical-to-electrical Converter


(From Used-Line T&M Specifications )
Status Discontinued

The SD42 Optical-to-electrical Converter head can be used to analyze optical signals in the 1000 nm to 1700 nm wavelength range. The pulse response of the measurement system is less than 55 ps FWHM (Full-width, Half-maximum), which is equivalent to a calculated bandwidth of DC to 6.4 GHz. The electrical output on the front panel is coupled to the adjacent sampling head via the semi-rigid coaxial link provided.

The SD42 is also equipped with an optical power meter for average power monitoring through a pair of voltage outputs on the front panel. Power from 5 nW to 5 mW can be measured.

  • Response Bandwidth: DC – 6.4 GHz
  • Wavelength Range: 1000 to 1700 nm
  • Optical Impulse Response Speed
    • With the SD24 and SD26, ≤55 ps (FWHM)
    • With the SD22, ≤60 ps (FWHM)
  • Conversion Factor: 25 mW/V
  • Conversion Gain: 40 mV/mW
  • Equivalent Display Noise
    • with SD-22: 10 µWrms typical
    • with SD-24/SD-26: 33 µWrms typical (unity dot response), <15 µWrms typical (with smoothing)
  • Aberrations (Step Response): <15% peak to peak in the first 400 ps following pulse input
  • Linear Response Range: <25 mW peak power, <5 mW mean power
  • Maximum Nondestructive Input: 75 mW peak power, 10 mW mean power
