|Sweep||200 ms/Div to 2 ns/Div in 1-2-5 sequence, ×10 magnifier down to 200 ps/Div, variable to ×2.5|
|Triggering||to 1 GHz|
|Jitter||less than 30 ps at 1 GHz|
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 oscilloscope readout. The display, scaled in seconds, provides the operator with a precise readout of the delay.
