Triggering source
CH1, CH2, LINE, EXT ( CH1 and CH2 can be selected only when the vertical mode is DUAL or ADD.
In ALT mode, if the TRIG. ALT switch is pushed in, it can be use for alternate triggering of two different source. )
Coupling
AC, HF-REJ, TV, DC
( TV-V/TV-H can be auto-set by TIME/DIV range. TV-V: 0.5s-0.1ms/DIV; TV-H: 50μs-0.1μs/DIV)
Polarity
+ / −
DC～5MHz: 0.5 DIV ( EXT: 0.1V )
5～20MHz
: 1.5 DIV ( EXT: 0.2V )(622G,623G,626G)
5～35MHz
: 1.5 DIV ( EXT: 0.2V)(635G)
DC～10MHz : 0.5 DIV ( EXT: 0.1V )
10～50MHz : 1.5 DIV ( EXT: 0.2V )
Sensitivity
TV (video signal): 2.0 DIV ( EXT: 0.2V )
AC coupling: Attenuate signal components of lower than 10Hz.
HF-REJ: Attenuate signal components of higher than 50kHz.
AUTO : Sweeps run in the free mode when no triggering input signal is applied.
(Applicable for repetitive signals of frequency 50Hz or over.)
NORM : When no triggering signal is applied, the trace is in the READY state and not displayed.
Triggering modes
SINGLE : One-shot sweep with triggering signal. Can be reset to the READY state by means of the RESET switch.
The READY lamp (LED) turns on when in the READY state or in the sweep operation
(623G, 626G , 652G , 653G and 658G only)
LEVEL LOCK and ALT
Satisfies the value of the above trigger sensitivity plus 0.5 DIV (EXT: 0.05V) for signal of duty cycle 20:80.
triggering
Repetition frequency:50Hz～20MHz(622G,623G,626G)
Repetition frequency : 50Hz ～35MHz (635G)
Repetition frequency : 50Hz ～ 40MHz
EXT triggering signal input
Input impedance
Max. input voltage
EXT HOR input terminal is used in common.
1M ohm ±2% // approx. 35pF
100V (DC+AC peak), AC: Frequency not higher than 1kHz
TRIGGERING
B triggering signal.
The A triggering signal of main sweep is used as the B triggering signal (623G,653G &658G).
