Model: 06201P, 06201KP, 06202KP

Accessories

Simple probe

AC/DC Power adapter (universal input voltage range)

Precautions

Do not apply voltage higher than the specified maximum input voltage to the instrument.

Do not attempt to directly measure wall power supply without a transformer.

Do not use power supply with voltage higher than 12V (DC or rms)

Panel Descriptions

Fig 1 shows the screen and various controls of the front panel. They are explained below.

Fig. 1

Screen

Y position indicator – the left small triangle – shows 0V position

Trig level indicator – the small right triangle – shows trigger threshold voltage level

Window position indicator – indicates the displayed portion of sample memory. “HOLD” is displayed when the oscilloscope is in HOLD state, which means capturing is halted until HOLD state is released. Scope setting indicators – their meanings are shown in Fig. 2.

Fig. 2

Power Supply Connector

Located at bottom right of the panel. 9 – 12V DC power supply (minimum 300mA capacity) can be connected to this connector.

Signal Input Connector

Located at bottom left of the panel.

Coupling Select Switch

This switch selects the coupling method to be used, i.e. AC coupling or DC coupling. When “Freq. M.” is selected, input is connected to frequency measurement circuit. The input to scope is internally disconnected.

Y Sensitivity Select Switches

There are two switches for Y sensitivity selection. The first one selects base value. The second selects multiplier. The two settings are combined to determine actual Y sensitivity. For example, when switch Y SEN. 1 is put at “0.1V” position and switch Y SEN 2 is placed at “X2” position, this means actual Y sensitivity is 0.2V per division.

SEC/DIV

Selects horizontal timebase. When this button is pressed, timebase display will be highlighted and timebase setting can be adjusted by pressing [ + ] and [ - ] buttons.

V.POS

Selects vertical position. When this button is pressed, the vertical position adjustment indicator will be highlighted and vertical position can be adjusted with [ + ] and [ - ] buttons.

H.POS

Selects horizontal position. When this button is pressed, horizontal position adjustment indicator will be highlighted and the displayed portion of capture buffer can be adjusted horizontally with [ + ] and [ - ] buttons.

MODE

Selects trig modes. When this button is pressed, trig mode adjustment indicator will be highlighted and trig mode can be selected with [ + ] and [ - ] buttons.

SLOPE

Selects trigger polarity. When this button is pressed, slope select indicator will be highlighted. Trigger slope will be toggled between rising and falling. Alternatively, trig slope can be changed with [ + ] and [ - ] buttons when the indicator is highlighted.

LEVEL

Fig. 3

Selects trigger level. When this button is pressed, trig level adjustment indicator will be highlighted and trig level can be adjusted with [ + ] and [ - ] buttons. Pressing this button again will select trig source between internal and external and enable/disable trig output.

OK

Switches oscilloscope between HOLD and RUN states. When this button is held down for more than 3 seconds the instrument will switch between Oscilloscope Mode and Frequency Meter Mode.

General Measurement

Example 1 Observe the test signal (Practice for basic operations)

Connect power supply and probe. Connect the red clip to the test signal terminal located at top-left corner of the panel, as shown in Fig. 3. Set Y sensitivity switch 1 (middle switch) to 1V position. Set coupling switch to DC position. Press [ V.POS ] button, adjust 0V indicator to the second to last vertical scale as shown in Fig. 3. Press [ SEC/DIV ] button, set timebase to 1ms. Set Y sensitivity switch 2 (top switch) to X2 position. Waveform similar to that shown in Fig. 3 should be seen. Change position of Y sensitivity switch 2 and you should see that the waveform amplitude changes accordingly. Change timebase setting to 0.5ms, for instance, and you should see the signal waveform is widened accordingly. Experiment with other settings. Now, select AC with the coupling switch and you should see that the waveform is shifted down to a position where the Y Pos. indicator is at its mid point. What you now see is a pure alternating signal.
