    摘要: A method for adjusting a time delay of a signal with respect to a reference event comprises the steps of displaying a graphical representation of the delay time on a display terminal, modifying the displayed graphical depiction to indicate a different time delay, and then adjusting the time delay of the signal to match the modified time delay indicated by the displayed graphical depiction. The display terminal is controlled by a display controller and the graphical depiction of the delay time is modified by an operator using a first means to transmit a first indicating signal to the display controller and a second means to transmit a second indicating signal to the display controller. Each time the controller detects a first indicating signal, the graphically displayed delay time is incremented and each time the controller detects a second indicating signal, the graphically displayed delay time is decremented. The controller automatically adjusts the actual test signal delay time after the displayed delay time has been adjusted.

    摘要: A gate circuit device, for example for an integrated circuit tester (10, 20), for variably setting signal propagation delay time (Tpd), for example to control timings of various output signals delivered from the IC tester to an integrated circuit (11) to be tested to predetermined values, comprises a gate circuit having a pair of emitter coupled transistors (01, Q2) and a constant current source transistor (Q3) connected to the emitter side of the pair of transistors (Q1, Q2) and a terminal for applying a predetermined level of voltage (VC, Vs) to the base of the constant current source transistor (Q3) to control constant current (Figure 1). As an alternative (Figure 6) to such voltage control of signal propagation delay time, a current adjustment circuit (CONT) may be utilized to generate current in a constant current source transistor (e.g. Q35) in response to a control current (I CNT )· Thus, the gate circuot device controls signal propagation delay time by regulating either voltage or current in response to control current.

    摘要: A high-speed programmable timing generator in which a continuously cycling binary count is compared with an input data word. Predetermined bits, starting from the highest- order end of the counter (24), can be selectively inhibited by an inhibit word (M) to effectively vary the cycle period of the counter. The digital word (D) with which the output of the counter is compared can be varied to set the reference phase of the output timing pulse stream. Further, fine delay adjustment (23) of the phase of the output timing pulse stream is effected by a controllable phase-locked loop (22).

    摘要: Separate electrical timing and load activation devices are provided for each of plural electrical loads and each device is in use connected to receive reference timing signals from a remote central unit. Each of the separate timing and toad activation devices measures a reference time interval accurately defined by the reference timing signals and subsequently activates its associated electrical load after a respectively corresponding predetermined time delay which is determined as a function of the locally measured reference time interval. The time interval may advantageously be measured by counting locally generated clock pulses, for example, in an up-down counter which after counting the pulses between two reference timing signals reverses direction and activates the load when the count reaches the initial value. The devices are especially useful for firing electric fuseheads for blasting detonators in a predetermined delay sequence.

    摘要: A circuit (40) constructed in accordance with this invention includes a ring oscillator (25) to provide a signal which is dependent on the propagation delays of the inverters (33, 34, 35) comprising the ring oscillator, therefore the frequency of the ring oscillator is inversely dependent upon the propagation delays of the inverter comprising the ring oscillator. Means (37) are provided to determine the propagation delay introduced by the components in the ring oscillator by measuring the frequency of the output signal produced by the ring oscillator which provides a signal to a multiplexer (36) which selects among a number of present delay components (26) those components which are necessary to ensure that the propagation delay caused by the circuitry (not shown) connected to the input lead (21) of the circuit constructed in accordance with this invention plus the propagation delay introduced by the selectable delay elements is nearly a constant propagation delay.

    摘要: A pulse delay circuit uses a cascaded series of inverting elements with input thresholds to delay the transitions of an input pulse as it progresses through the series. The output of each inverter charges a capacitance in one polarity, but cannot discharge it. The discharge is achieved by current sources connected to the capacitors, charging them in a direction opposite to that of the inverter outputs. This produces a ramp which subsequently produces an abrupt transition aslhe ramp eventually crosses the input threshold. In this way every other inverter delays the leading edge, while the alternate intervening inverters delay the trailing edge. A final capacitance-tolerant inverting element with a threshold produces abrupt transitions for each transition as its input, to create a delayed replica of the input pulse. Asymmetries in the relative delay of the leading and trailing edges are corrected either by independently controlling one of the current sources or one of the thresholds.
