1
Will not trigger on the sine waves of 8 div amplitude or less (internal), or 3 V or less (external) at
60 Hz or below.
2
For Internal Triggering only, the specified -3 dB frequency of the Vertical System replaces any
frequencies in the above table when the number in the table is greater than the -3 dB frequency of
the Vertical System.
3
Triggering signal amplitude requirements increased by factor of 10 for EXT - 10 operation.
4
The specified -3 dB frequency of the Vertical System replaces any frequencies in the above table
when the number in the table is greater than the -3 dB frequency of the Vertical System.
