Coax cable characterization
This page summarizes measured performance of coaxial tether cables for Miniscopes: which cables work at which lengths, and what supply voltage your cable needs. Detailed per-cable results are linked at the bottom.
Which cable lengths work?
Each curve is one cable type. The score combines eye opening, link margin, and attenuation into a single 0-1 number; the shaded bands show the recommended (green), marginal (yellow), and not-recommended (red) regions.
What supply voltage do I need?
Thin coax drops voltage, so each cable and length has an allowable supply window: the minimum keeps the Miniscope above its regulator dropout at full load; the maximum stays under the regulator's input limit. The dotted line marks the USB 5 V rail for reference -- DAQs can also be powered from an adjustable supply anywhere in the window.
