Figure S-l. Connections Required for a Two-Tone Scalar Network Analyzer Measurement System
1. Designate one swept signal generator as the master, the other as
the slave.
2. Make the connections.
3. To avoid synchronization problems, always set up the slave
(frequency and power) before setting up the master.
4. Set up the master (frequency, power, and sweep time).
5. Set the sweep time on the slave.
6. Configure the swept signal generators for step sweep, or ramp
sweep.
7. Select the appropriate triggering scheme.
8. Activate the slave mode on the slave swept signal generator.
9. Activate the master mode on the master swept signal generator.
By connecting the master’s 10 MHz reference standard to the slave’s
10 MHz reference input, the master swept signal generator’s
timebase
supplies the frequency reference for both swept signal generators.
In step sweep measurements, if the master swept signal generator
is not connected to an external controller, it must automatically
trigger the
steps.
Set
Step Swp Pt Trig Auto on
the
master.
When a the scalar network analyzer is the step sweep controller, set
Step Swp Pt Trig Bus on
the
master swept signal generator so
that the analyzer can trigger the steps.
