LC_XO GPSDO User Manual
Set the communications parameters as follows:
•
Comm port: Windows will assign a comm port. Enter that number in the Com box.
•
Baudrate: 115,200
•
Data bits: 8 bits

Once you have configured the communication parameters, press the “OK” button to close the

For proper communication between the LC_XO GPSDO and GPScon, SYST:COMM:SER:ECHO
must be set to ON. Although this is the factory default, it could have been set to OFF for use with the
Z38XX utility. To set it to ON, open the manual command dialog box (see Section
). Manually
enter the command SYST:COMM:SER:ECHO ON and press the Send button.
3.3.1.3 Auxiliary parameters
After pressing the “Options” button, you can select “Auxiliary” and set other options or
measurements. See
for an example of an auxiliary measurement. You will notice that the
“Aux 1 request string” has been set to
meas:current?<CD>
and the “Log Aux1” box is checked.
In the area below labeled “Traces to be visible on the graph”, the box “Aux 1” is checked and the
label “OCXO curr” has been added.
