This procedurechecks the sample rate portion of the Delta Time Measurement

Accuracy as listed in the Specifications section.The previous procedure, Check

Long-TermSample Rate and Delay Time Accuracy, on page 2--39,verified the

“PPM” portion of the delta time specification.

1. Install the test hookupand preset the instrument controls:

a. Initialize the oscilloscope:Press the DEFAULT SETUP button.

b. Hook up the pulse generator as shown in Figure 2--18.

HSet the pulse generatoroutput for a positive-going pulse with a

280 ps --800 ps rise-time, as shown in Table2--4 on page 2--44, and

for the fastest possible rep rate (at least 1 kHz).

HSet the pulse generatoroutput for about 500 mV. (This amplitude

can be adjustedlater to get a 5-division pulse on the screen.)

c. Modify the initialized front-panelcontrol settings:

HFrom the toolbar,click the Vert button. Set the termination of the

channel to 50 Ωby selectingthe channel tab and clicking the

Termination50 Ωbutton.

HPressAUTOSET. You may see both positive and negative pulses.

Adjust the TriggerLEVEL knob so that the trigger level is about

50% of the rising edge of the positive pulse.
