Checking Performance -222 DSO Operators
1. Check Trigger Sensitivity
a. Connect the Leveled Sine-Wave Generator via a 504 termi-
nation and a BNC-to-male probe-tip adapter to the CH 1 probe tip.
b. Set the Sine-Wave Generator for a 5-division display ampli-
tude at 20 MHz.
c. Set the CH
1 VOLTS/DIV to 50 mV for a 0.5 division display
amplitude.
d. CHECK-for a stable display with the TRIG'D indicator on.
2. Check Trigger LEVEL Control
a. SET: CHIVOLTSIDIV 0.2 V
SECIDIV 5 FS
Trigger MODE AUTO BL
b. Set the Sine-Wave Generator for a 5-division display ampli-
tude at the 50 kHz reference frequency.
c. Adjust the Trigger LEVEL control for a stable trigger
d. CHECK-that the signal remains triggered while the trigger
point indicator
" + " is on the positive slope when rotating the Trigger
LEVEL control through its range.
e. Set the Trigger SLOPE to
'I-."
f. CHECK-that the signal remains triggered while the trigger
point indicator
" + " is on the negative slope when rotating the Trigger
LEVEL control through its range.
g. Set the CH
1 VOLTSIDIV to 50 mV.
h. Set the Trigger LEVEL control to position the trigger indicator
(+) to 1 division below the positive peak of the signal. (Use theverti-
cal POSITION control to bring the peak of the signal on screen to see
the trigger position on the waveform.)
i. Position the waveform vertically to place the bottom of the sig-
nal 1 division above the center horizontal graticule line.
j. CHECK-that the signal remains triggered with the TRIG'D
indicator light on.
