The '''Tektronix 7D11 Digital Delay''' can be used to delay a [[:Category:7000 series horizontal plugins|7B timebase]] by a given time up to 1 second in 100 ns increments, or by a number of events (1 to 10<sup>7</sup> at up to 50 MHz). The selected delay is displayed in the on-screen readout (7 digits). An analog fine delay control can add from 0 to 100 ns in delay mode. The 7D11 has an internal reference oscillator or can accept an external 1 MHz input. The [[7D10]] is essentially the same but without this oscillator and time delay mode. | The '''Tektronix 7D11 Digital Delay''' can be used to delay a [[:Category:7000 series horizontal plugins|7B timebase]] by a given time up to 1 second in 100 ns increments, or by a number of events (1 to 10<sup>7</sup> at up to 50 MHz).

Two switches internal to the 7D11 allow the user to enable Z axis modulation and "echo mode" to double the indicated delay, respectively. The latter is provided for radar or [[TDR]] applications where the delay time of the reflected pulse is twice the cable delay. | Two switches internal to the 7D11 allow the user to enable Z axis modulation and "echo mode" to double the indicated delay, respectively.
