Thanks for the previous answer on how to generate an arbitrary waveform. Is there any way that, ins ...

Sorry, it hasn't such function to generate a arbitrary waveform, I suppose.

Input and Output Connections

On the top of the test device has two BNC jack signal inputs for oscilloscope, and one BNC jack signal output for waveform generator.

Look at the bottom on the front panel of the test device. There are four safety banana jack inputs for multimeter. See Figure 9.

Making Oscilloscope Input Connections

To make oscilloscope measurements, connect the red ring voltage probe to input CH1, the green ring probe to input CH2. Connect the short ground leads of each voltage probe to its own reference potential.

2. Adjusting the Probe Type Settings

To obtain correct measurement rsults the test device probe type settings must correspond to the connected probe types.

To select the input CH1 probe setting do as below:

1.   Display the input CH1 channel menu.

2.   Turn page 2 open the probe attenution meanu.

3.  Select the voltage probe attenuation factor.

Selecting an Input Channel

To select an in put channel, do the following:

1.  Press the channel key to display the channel menu.

2.  Press F1 soft key to select CH1 or CH2.

3.  Press F2 soft key to turn on CH1 or CH2.

Displaying an Unknown Signal with Auto

The Auto function lets the test device display complex, unknown signals automaitically. This function optimizes the position, range, time base, and triggering and assures a stable display of virtually any waveform. If the signal changes, the setup is automatically adjusted to maintain the best display result. This feature is especially useful for quickly checking several signals.

Perform an Auto Set. AUTO appears at the top left of the screen.

The bottom line shows the range, the time base, and the rigger information.

The input CH1 zero icon at the left side of the screen identifies the ground level of the waveform.

Use the move keys on the keypad to change the view of the waveform manually.

Making Automatic Oscilloscope Measurements

The test device provides 2 kinds of automatic measurements: frequency and amplitude.

To choose a frequency measurement for input CH1, do the following:

1. Display the oscilloscope menu.

2. Turn page 3/4 to show Measure label.

3. Press F2 softkey to open measure menu.

4. Enable measure items: Frequency and Amplitude message label on the top right of the display screen.

Tip

In the measurement result, the yellow font is the result of CH1, and the green font is the result of CH2.

Freezing the Screen

You can freeze the screen (all readings and waveforms) at any time.

1. Freeze the screen. The key illumination is on in red.

STOP appears at the top left of the screen.

In scope mode, stop or run the waveform acquisition

Hold appears at the left bottom of the screen.

In DMM mode, hold the measuring data or update data
