3.2.1.2 Serial Echo
For serial communication with Z38XX to work correctly, Serial Echo must be turned off (see the
explanation in the Z38XX manual). To turn off serial echo, click on the Manual Command Entry tab.
The drop-down menu shown in
Figure 3.2 will appear. Scroll all the way down and click on
SYST:COMM:SER:ECHO OFF. Wait until the yellow indicator is lit and then press “Send”. This
will send a command to the LC_XO and turn off serial echo.
Note: If you want to run GSPcon utility subsequently, be sure and turn back on Serial
Echo as that program requires it. To do so, click on the Manual Command Entry tab
and scroll down to the menu item SYST:COMM:SER:ECHO ON. Wait until the yellow
indicator is lit and then press ”Send”.
