TB-01

The TB-01 contains a high-speed leading-edge discriminator circuit that can be configured to detect positive or negative pulses and to trigger on rising or falling edges. NIM or TTL-compatible outputs can be selected, and both the threshold voltage and blocking width/output duration can be adjusted.

Applications

The TB-01 pulse converter/discriminator has more uses than we can think of. Here are just a few...

• Use the TB-01 with a photodiode to generate sync pulses from your mode-locked laser with picosecond timing performance
• Convert positive and negative pulses to fast-NIM
• Convert positive and negative pulses to 50Ω TTL
• Convert fast-NIM to TTL and vice versa
• The TB-01 can even be used as a photomultiplier discriminator

Performance Data

Application 1: Laser synchronization

This TCSPC instrument response function from a femtosecond laser was obtained using a photodiode and the TB-01 pulse converter on the Start channel and a MCP-PMT on the Stop channel.  The TB-01 was close-coupled to the photodiode on the optical table.  The TB-01’s jitter contribution is negligible in this case.

Application 2: TB-01 as photomultiplier discriminator

Comparison of a linear-focused PMT’s instrument response function measured using a TB-01 and a NIM style leading-edge discriminator.  FWHMs obtained were 1.60ns for both devices.
