2. Sync Output
Press Utility → NextPage4/4→ AWG → Setting → Sync Output , the AWG provides
Sync output through the [Aux In/Out] connector on the rear panel. When the Sync Output
is on, the port can output a CMOS signal with the same frequency as basic waveforms
(except the Noise and DC), arbitrary waveforms, and modulated waveforms (except
external modulation).
3. OVP(over voltage protection)
Press Utility →NextPage4/4→ AWG → Setting → OVP to turn on or off the function. If
the state is set to ON, overvoltage protection of AWG output port take effect once the
condition is met (the absolute value of input voltage is higher than 4V±0.5V). When
overvoltage protection occurs, a message will be displayed and the output is disabled.
4. Default
Press Utility →NextPage4/4→ AWG → Setting → Default to recover the default values of
the AWG (Sine, 1.000 KHz, 4.000Vpp, 0.0mVdc, High_Z, Sync output off, OVP On).
5. Zero Adjust
Press Utility →NextPage4/4→ AWG → Setting → Zero Adjust. The AWG can be
calibrated by using Auto mode or Manual mode. The method of AWG calibration
Is covered below.
Auto mode:
This mode can only be performed with the oscilloscope channel1. Connect the output of the
AWG to the oscilloscope’s channel1, press the Auto soft key, then the AWG starts
automatic calibration, and displays ”Zero Adjust Success!”
M
anual mode:
The AWG can be manually calibrated through any channel on the oscilloscope. Take
channel 2 as an example.
Connect the output of AWG to the oscilloscope’s channel 2, turn on channel 2, and set
DC coupling, no bandwidth limit, Probe is 1X.
Adjust the voltage of channel 2 channel to 1mv/div, and make the waveform visible in the
oscilloscope interface, press the Measure and measure the mean value of channel 2.
Press the Manual and rotate the knob to adjust the waveform, so that the mean value of
the observed CH2 will be in the range of ±1mv, and then press the Save, the oscilloscope
display" Zero Adjust Success! ".
