Time-to-Digital Conversion for Space Applications

Time-to-Digital Conversion for Space Applications

Are you a user of Earth-Observation LiDAR instruments, space-science mass spectrometers, ISAM/space-domain awareness proximity detectors or optical communications transceivers? Do you need to calculate time-of-flight precisely? Do you need to calculate absolute time for applications such as secure quantum key exchange via satellite? A Time-to-Digital Converter (TDC) is like a stopwatch measuring the elapsed interval between two events with picosecond precision, converting this into a digital value for post processing.

Oscilloscope Probing Your Satellite

Oscilloscope Probing Your Satellite

When designing space electronics, particularly during the early prototyping stage or if qualification or flight hardware doesn’t function as intended, the humble oscilloscope is often used to verify the presence, timing and quality of key signals. Many types of measurements are now possible, e.g. analogue voltages, currents, power, logic, EMC, optical and high voltage, but how do you choose the right probe for your testing needs? Is a $10 probe suitable or do you need to buy one that costs $10k?
