A AND B TRIGGER
Trigger sensitivity is defined as the minimum peak-to-peak sine-
wave trigger signal amplitude required to show the test signal with
horizontal jitter of less than 3.0% of one period {p-p viewed over
two seconds).
0.35 division from DC to 25 MHz, increasing to 1.0 division at
150 MHz.
1.4 division from DC to 50 MHz; increasing to 2.2 division at
100 MHz. 0.5 division or less will not trigger.
0.35 division from DC to 50 kHz; attenuates signals above the
upper —3 dB cutoff frequency of 70 kHz.
0.35 division from 100 kHz to 25 MHz, increasing to 1.0 division
at 150 MHz; attenuates signals below the lower —3 dB cutoff fre-
quency of 50 kHz.
0.35 division from 50 Hz to 25 MHz, increasing to 1.0 division at
150 MHz; attenuates signais below the lower —3 dB cutoff fre-
quency of 20 Hz.
0.5 division of composite sync will achieve a stable display.
10 Hz.
+20 divisions referred to the appropriate vertical input.
This range is sufficient to allow triggering at any point on a.
displayed waveform for all modes except “ADD.” In ADD, the
combined range of the two position controls exceeds the trigger
level range, making it possible (though unlikely} to pull a signal on
screen for display but fail to trigger on it due to insufficient trigger
level range.
+(0.3% of reading + 10% of one vertical division).
increases A Sweep holdoff time by at least a factor of 10.
