TRIGGER MODE...…………..(28)
Select the desired trigger mode.
AUTO : When no triggering signal is applied or when triggering signal frequency is less than 50 Hz, sweep runs
in the free run mode.
NORM : When no triggering signal is applied, sweep is in a ready state and the trace is blanked out. Used primarily
for observation of signal
≤ 50 Hz.
SINGLE : Use for single sweep.(Except 622G & 635G)
Push to RESET: Operation(one-short triggering operation), and in common as the reset switch. When
these three buttons are disengaged, the circuit is in the single trigger mode. The circuits is reset as this button is
pressed. When the circuit is reset, the READY lamp turns on. The lamp goes out when the single sweep
operation is over.
Time Base
(A) TIME/DIV........………......(18)
Select the sweep time of the A sweep. (A and B sweep in common for 658G only, B TIME/DIV < A TIME/DIV)
B TIME/DIV...........………...(43) (623G&653G only)
Select the sweep time of delayed sweep (B sweep).
SWP.VAR............………….....(21)
Vernier control of sweep time. When SWP.UNCAL(19) button is pushed in, the sweep time can be made slower by a factor
≥2.5
of the indicated value. The indicated values are calibrated when this button is not pushed in.
POSITION..........……………..(34)
Horizontal positioning control of the trace or spot.
×10 MAG............………….(33)
When the button is pushed in, a magnification of 10 occurs.
DELAY TIME ...........… ........(44)( 623G&653G only)
Vernier control of the delay time selected by the A TIME/DIV(18) and B TIME/DIV(43) switch to finely select the portion of the
A sweep waveform to be magnified.
HORIZ. DISPLAY MODE.......(38)( 623G, 653G & 658G only)
Select A and B sweep modes as follows:
A
: Main sweep(A sweep) mode for general waveform observation.
A INT : This sweep mode is used when selecting the section to be magnified of A sweep, in preparation for delayed sweep.
The B sweep section(delayed sweep) corresponding to the A sweep is displayed with a high intensity beam.
