TRIGGERING |
|
| Triggering Source | CH 1, CH 2, LINE, EXT (CH 1 and CH 2 can be selected only when vertical mode is DUAL or ADD). In ALT mode, if the TRIG.ALT switch is pushed in, it can be use for alternated triggering of two different source. |
| Coupling | AC : 20Hz to full bandwidth |
| Slope | +/- |
| Sensitivity | 20Hz ~ 2MHz : 0.5 DIV, TRIG-ALT : 2 DIV, EXT : 200mV |
| 30 ~ 40MHz : 3.0 DIV | |
| TRIG –ALT : 3 DIV, EXT : 800mV | |
| TV : sync pulse more than 1 div (EXT : 1V) | |
| Triggering Modes | AUTO : Sweeps run in the free mode when no triggering input signal is applied. (Applicable for repetitive signals of frequency 25Hz or over). NORM : When the triggering signal is applied , the trace is in the ready state and not displayed. TV-V : This setting is used when observing the entire vertical picture of television signal. TV-H : This setting is used when observing the entire horizontal picture of television signal. (Both TV-V and TV-H synchronize only when synchronizing signal is negative). |
| EXT Triggering Signal Input Input Impedance Max. Input Voltage |
Approx. : 1M Ohm//Approx. 25pF 400V (DC + AC peak), AC : frequency not higher than 1KHz. |
