Sequence for Multiple
Controllers
The run-time measurement sequence for multiple controllers is similar to a
single controller shown earlier. See “Starting Run-Time Mode” on page 6-14
for more information on this sequence. The sequence for multiple
controllers has additional steps to allow communications between the
controllers. Refer to Figure 6-3 on page 6-19 and Figure 6-4 on page 6-20
for the actual run-time measurement sequence.
Using IMM vs. TTL
Trigger for Source 1
Refer to “Source 1 IMM, TTL or REM1 trigger diamond in Figure 6-3.
When using multi frequencies:
• The RF Source controlled by the master 85330A should use the TTL
trigger.
• The other RF Source (not controlled by the master 85330A) should use
the IMM trigger.
