Photodetector Time-Domain Noise Measurements

Dataset Description

This dataset contains oscilloscope recordings of the electrical noise of the photodetector system under preamplifier sensitivity setting of 2.00E-05A/V. During these measurements, the sample was kept in complete darkness to ensure that only intrinsic detector and amplifier noise were recorded.

Channel Description

CH1 – Noise signal (voltage output from the transimpedance amplifier).
No optical modulation was applied during these measurements.


Data Format

Column 1 – Time (s)
Column 2 – CH1 (noise voltage signal, V)

Acquisition Parameters

Sample Interval – 0.00016 s
Record Length – 125000 points

This corresponds to:

* Total acquisition time ≈ 20 s
* Sampling frequency ≈ 6.25 kHz

The CSV file was exported directly from a Tektronix oscilloscope via a USB stick.
