We present the initial results of an experimental study of a beam timing monitor based on an optoelectronic technique. This technique uses the electrical signal from a beam position monitor to modulate the amplitude of a train of laser pulses, converting timing jitter into an amplitude jitter. This modulation is then measured with a photodetector and sampled by a fast ADC. This approach has already demonstrated sub-100 fs resolution and promises even better results. Additionally, we are planning to use the technique as a way to extract the maximum possible bandwidth from a BPM, avoiding the dispersion typical of long RF cables. We show our initial results using signals from the Advanced Light Source storage ring.
