The Delay Amplifier that war used in the exercise was an ORTEC Model 427A Delay. This DA is suitable for any general-purpose variable delay of linear or logic signals within the range from 0.25 to 4.75 s, with using any combination of the following buttons on the front-panel: 0.25, 0.5, 1.0, 1.0 and 2.0 s. (The minimum, zero, delay is 60 ns)

On: push the button to right Off: push the button to left

All signals, of either polarity and up to 10 V in amplitude, are delayed by the selected time and are reproduced at the outputs. (There are two outputs, one with impedance 1 on the front-panel and the other 93 on rear-panel)

This DA can delay the earlier of two signals such that the pair of signals will coincide in a subsequent analysis.

The input impedance is not affected by the selected delay so that no signal loading change occurs.

Rise time and bandwidth is a function of delay: The rise time 400 ns. The minimum (when zero delay) rise time is 280 ns The bandwidth 0.875 MHz. The minimum (when zero delay) bandwidth is 1.25 MHz

The coupling for DA in this exercise was: Maim Amplifier, output --> input, Delay Amplifier, output --> input, ADC/MCA
