The Tektronix DL2 Digital Latch is a plug-in for 7000-series scopes that functions as a glitch detector extension to the 7D01 logic analyzer. There is a TM500 counterpart, the DL502.
It connects between the P6451 probes and the 7D01 and receives the latter's store clock via a front panel BNC connector. Short pulses ≥5 ns are stretched to the clock period.
