Touch
Output Load
to toggle between 50
Ω
and High-Z.
–
The selected output load value must match the load impedance.
Otherwise, the amplitude and offset of the output waveform of AWG will
be incorrect.
•
Touch
OVP
to toggle over voltage protection on and off.
–
When OVP is enabled, the output will be turned off automatically once
the protection condition is met.
–
The protection condition is when the absolute value on the output port
is higher than 4 V ± 0.5 V). At the same time, a warning message is
displayed.
•
Touch
Zero Adjust
to perform a zero adjustment.
–
Auto Steps
: In this mode, the adjustment can only be performed with
CH1 of the oscilloscope. Connect the output of AWG to CH1 of the
oscilloscope, press
Auto
, and the AWG will start to automatically
adjust.
The scope will display “Zero adjust completed!” when the
adjustment is done.
–
Manual Steps
: The AWG can be manually calibrated through any
channel on the oscilloscope. Take CH2 as an example:
1.
Connect the output of AWG to CH2, open CH2, set it to DC
coupling, turn on bandwidth limit, and set the probe attenuation to
1X.
2.
Set the vertical scale of CH2 to a small scale such as 1mV/div. Turn
on measure and set the parameter to Mean of CH2.
3.
Press
Manual
and rotate the universal knob to adjust the
compensation value, until the mean value of CH2 is within ±1mV,
and then press
Save
.
–
The output zero error of the AWG can be calibrated by using auto mode
or manual mode.
–
When AWG outputs 0V DC signal, the measured mean value of the
corresponding channel is within±1mV.
