Tektronix DL2
Digital Latch DL2 Compatible with 7000-series scopes Produced from 1978 to (?) Manuals Tektronix DL2 Manual (All manuals in PDF format unless noted otherwise)

Manuals – Specifications – Links – Pictures

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.

Key Specifications

Number of channels	16
Minimum pulse width	5 ns
Minimum clock period	20 ns

Internals

The data path in the DL2 is built using standard 100k ECL circuits. The –4.8 V and –2 V ECL supplies are generated by a 555-driven switcher powered off the ±15 V rails (same board as in the 7D01).
