Operating Manual for UTD2000/3000

Term explanation:

FFT resolution: It is defined as factor of sampling

and calculation point. FFT resolution increases when

sampling rate decreases for fixed calculation point

quantity.

Nyquist frequency: Original waveform can not be

reset until using sampling rate of at least 2f for

waveform with the maximum frequency of “f”. It is

also called as Nyquist guideline. “f” refers to Nyquist

frequency and “2f” refers to Nyquist sampling rate.

Reference waveform

Please press [STORAGE]key and enter into the

second page to select call-out for 7-inch oscillograph

(namely, UTD2000L series).

2. Please press [RefA] (RefA reference option) and

select information source then select its position by

rotating multi-purpose knob in upper part of front

panel. 1～10 (or 1～20) can be selected for the

position. Press “call-out” to call out waveform which

is stored in

the position originally after selecting a certain

position such as “1”. Please plug in U disk if waveform is

stored in the U disk. There are 2 options for magnetic disk

as follows:

DSO/USB; Please press [F2] key and select

Please refer to waveform stored in nonvolatile

USB. (The menu can not be activated until plugging in U

memory (NVM) of digital storage oscillograph or

disk.) Called out waveform is displayed on the screen for

peripheral U disk with name of RefA and RefB as

waveform called out and stored from U disk. Please press

follows. Please operate according to following steps
