3.5 Count
This function/arbitrary waveform generator can measure the frequency and
duty ratio of the signal which is compatible with the TTL level. The range of
frequency measurement is 100mHz~100MHz. When frequency meter is used,
the signal compatible with TTL level is input through the Input/CNT/Sync
connector.
Press the button, the device will read the signal “frequency” and “duty
ratio” values. When no signal is input, the count parameter always displays
the value measured last time.
The count parameter refreshes the display only when you input a signal that
is compatible with the TTL level to the Input/CNT/Sync connector.
Chapter 4 Advanced Applications
This chapter introduces the AM, FM modulation. Press the Mode key to enter
modulation, and press the Mode key again to exit.
4.1 Output Modulation Waveform
4.1.1 Amplitude Modulation (AM)
Select AM modulation
Press the Mode button, then move the cursor to AM by and press OK to
enable AM. AM modulation is selected by default when the modulation is on.
Then the instrument will output the modulated waveform with the currently
set modulation wave and carrier wave.
Select carrier waveform
The carrier waveform can be: sine wave, pulse wave, ramp wave or arbitrary
wave, the default is sine wave. After selecting the AM modulation, press the
STD/MOD button and STD is selected.
Picture 4-1 Enable AM modulation
Picture 4-2 Set AM carrier waveform
Select the carrier waveform by pressing the waveform selection button:
