Uni-T UTD2052CEX [54/120] Operating manual for utd2000 3000

connected to EXT TRIG interface. Signal can be

used for E XT and EXT can be used within signal

trigger level scope of -3V to +3V

utomatic trigger: The system will acquire

waveform data automatically so as to displa

scanning base line on the screen without trigger

signal input. It will convert to trigger scannin

automatically for signal synchronization whe

producing trigger signal

It is allowed to select EXT/5 for oscil lograph of 5.7-

inch screen. Outer trigger shall be divided by 5 so

that trigger scope can expand to -15V to +15V for

trigger of di gital storage oscillograph under large

signal

Municipal power: Such trigger mode can be used

to observe signal with regard to municipal power

For instance, it can provide relationship betwee

lighting equipment and power supply equipment so

as to gain stable synchronization

2 Trigger mode: It is to determine behavior mode

of digital storage oscillograph without trigger event

This digital storage oscillograph can also provide

triggers, namely, automatic, normal and single

trigger modes

Operating Manual for UTD2000/3000

Note: Without trigger signal is allowed under

“

automatic” mode when setting scanning waveform to

5-ms/div or less time base

Normal trigger: Digital storage oscillograph ca

not acquire waveform until meeting t rigger conditions

under ordinary trigger mode. Trigger scanning can b e

produced when producing trigger signal

Single trigger: User can press “operation” button

once under single trigger mode for entry and trigger

waiting for digital s torage oscillograph. It will sample

and display all acquired waveform then stop after

digital storage oscillograph detects once trigger
