(requires Option 001)
This section gives an overview of the basic techniques used to program the
Phase-Lock option (option 001). This section is only an overview and does
not give all of the details you will need to write your own application
programs. Refer to “Application Program Examples,” later in this chapter
for more details and examples. Also refer to the programming reference
manual that came with your computer for details on outputting command
strings and entering data.
The front-panel 10 MHz Ref In terminal allows you to synchronize one or
more function generators with an external 10 MHz signal. The following
statements show how to configure a single instrument for synchronization
with an external signal:
Select sine function at 10 MHz
Set phase offset to -90 degrees
Set phase reference to zero
APPL:SIN 10E+6, 5.0
PHAS:ADJ -90 DEG
PHAS:REF
