To Phase Lock Using the

Counted Burst Mode

(requires Option 001)

In the counted burst mode, you can synchronize phase-lock signals using an external trigger from the faceplate Ext Trig terminal or VXIbus TTLTRG lines. The following statements show you how to synchronize two function generators in the counted burst mode using the Ext Trig terminal (send the commands to both function generators):

Send these commands to both function generators:

APPL:SIN 10E+3, 5.0	Set both to the same frequency
BM:NCYC INF	Set burst count to “INFINITY"
TRIG:SOUR EXT	Set trigger source to external
BM:STAT ON	Enable the BMod LAST
Send this command only to the "left" function generator:
OUTP:TRIG:IMM	source trigger signal from "left"
	instrument to rught instrument

Figure 2-13.

To use TTLTRG lines send these commands to both generators:

APPL:SIN 10E+3, 5.0	Set both to the same frequency
BM:NCYC INF	Set burst count to “INFINITY"
OUTP:TTLT4 ON	Enable TTLT4 line to source
TRIG:SOUR TTLT4	Set trigger source toTTLT4 line
BM:STAT ON	Enable the burst mode LAST
Send this command only to the "left" function generator:
OUTP:TRIG:IMM	source trigger signal from "left"

You don’t have to connect between the Ext Trig terminals when using the TTLTRG lines.
