Figure 4. THE GATING BOARD.

Figure 4

Measures 7” × 4” and costs approximately $500 (with assembly). It delivers a TTL gating acquisition window of any length and at any time relative to the incoming signal. It also uses a stackable design that allows simultaneous and cumulative gating of several incoming signals. A miniaturized version of this board is currently designed.
