3. Confirm Delayed trigger system is within limits for Trigger-level/Threshold

accuracy:

a. Select the Delayed time base:

H Press HORIZONTAL MENU.

H Press the main-menu button Time Base.

H Press the side-menu buttons Delayed Only and Delayed Trigger-

able.

H Set D (delayed) horizontal SCALE to 500 s.

b. Select the Delayed trigger system:

H Press SHIFT; then press the front-panel DELAYED TRIG button.

H Press the main-menu button Level.

c. Measure the test signal: Press the side-menu button SET TO 50%.

Read the measurement results in the side (or main) menu below the label

Level.
