b. Adjustments. Perform SECTION IV below.
10. Triggering
a. Performance Check
(1) Press ∆V pushbutton to off (cursors off).
(2) Push TRIGGER MODE switch down to NORM.
(3) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 10 mV at 1
kHz frequency.
(4) Set CH 1 VOLTS/DIV switch to 2 mV.
(5) Adjust TRIGGER LEVEL control for most positive voltage that produces a
barely triggered display for both + and - SLOPE. If A TRIGGER LEVEL readout
indication is not within limits given in + peak column of table 6 for 2 mV setting, perform b
below.
(6) Adjust TRIGGER LEVEL control for most negative voltage that produces a
barely triggered display for both + and - SLOPE. If A TRIGGER LEVEL readout
indication is not within limits given in - peak column of table 6 for 2 mV setting, perform b
below.
(7) Repeat technique of (5) and (6) above for remaining VOLTS/DIV switch settings
and oscilloscope calibrator outputs listed in table 6.
