Notes:
- The ET-3000, ET-3010 and ET-3040 can be ordered with an optional 5V wall plug in power supply. See Price List for cost.
- Standard photodetectors have a positive bias. Photodetectors with a negative bias are available as a special option.
- These photodetectors are not internally terminated. A 50Ω termination is optimal.
- For more information on our biased InGaAs photodetectors, please view the Photodetector Application Notes page in the Publications & Technical Support section of our website.
- For information on the use of our biased InGaAs photodetectors, please view the Photodetector Users Guide page in the Publications & Technical Support section of our website.
- The ET-3020 and ET-3040 have active areas large enough to provide power measurements. For information on how to calculate the incident power on the photodetector using the output voltage on your oscilloscope, please visit our Incident Power Calculator in the Publications & Technical Support section of the website.
- To convert frequency response to time domain response or vice versa, please view our Frequency Response to Time Domain Response Calculator on our website.
- To convert between watts and dBm please view our Power Conversion Calculator on the Publications & Technical Support section of this website.
Warranty/Terms and Conditions: Please visit the Photodetector Warranty/Terms and Conditions pages in the Publications & Technical Support section of this website.
