A ramp generator is started when the trigger signal arrives. The delayed sweep is started when a | |||
comparator detects that the ramp has reached a control voltage, set by the front panel knobs. | |||
The control voltage is therefore proportional to the amount of delay and is measured using a | |||
[[155-0185-00]] 4-digit DVM circuit, then displayed on the [[7000 series readout system|oscilloscope readout]]. | |||
The display, scaled in seconds, provides the operator with a precise readout of the delay. | |||
Other custom Tek ICs used: [[155-0150-00]] trigger detector, [[155-0160-00]] trigger amplifier. | |||
