Composite Video Signal Display
When inputting composite video signals, set the [TRIGGERING] MODE to either
TV-FRAME or TV-LINE. Also switch the SLOPE control in accordance with
signal polarity.

DUAL TRACE OPERATIONS
Switching Vertical Operation Modes
When the iiiiigilMI MODE control is set at CH2, the CRT screen will display
the signal applied to the channel 2 INPUT terminal. The amplitude can be altered
using the channel 2 VOLTS/DIV control. The procedures for switching the sweep
time and setting the trigger point are the same as for channel 1.
When the ESSI MODE control is set at ALT, the CHI and CH2 signals are
displayed one after the other for each sweep.
When the BlaUBMl MODE control is set at CHOP, the CHI and CH2 signals
are sub-divided according to time and displayed on the screen.
When the MiaaWHW MODE control is set at ADD, CHI and CH2 signals will be
combined (CH1+CH2) on the CRT display screen. If the CH2 INV control is
pressed in this condition the differential (CH1-CH2) of the two channels will be
displayed. In order to measure displayed waveforms at the ADD setting, it is
necessary that the VOLTS/DIV control settings be the same for both channels.
Switching Trigger Source
When themaWMMWMODE control is set at CHI, ALT, CHOP, or ADD and the
SOURCE control is set at VERT MODE, the signal source for the trigger becomes
channel 1. At this time, if the CHI signal is too complicated, making the trigger
point too difficult, switch the SOURCE control to the CH2 setting. The CH2
signal will be simple enough for a stable trigger point setting. However, when
the waveforms of both channels are too complicated, use an external source to
set the trigger point.
If signals having different frequencies are input to CHI and CH2, set the
ES355SIMODE selector to ALT and SOURCE selector to VERT MODE. Input
signals to CHI and CH2 are used as the trigger signal sources, which alternate in
every sweeping. Thus, both signals are triggered.
