RF Communication and Signals Experiments
Experiment 9: Production Line Applications
Relevant
information A spectrum analyzer can be used in Pass/Fail testing of RF
communication products. Testing can be done either manually
with a stand-alone instrument or via remote control using a PC.
When using remote control, the spectrum analyzer parameter
settings and test results can be returned remotely. This saves a lot
of time and can improve the efficiency of a production line. In
this experiment, we will imagine that the GRF-1300A is in a
production line environment. We will use the limit line function
to perform a simple test to see if a product has passed the test and
return the test results using remote commands.

Experiment
goals 1. Learn how to edit the pass/fail limit lines and understand how
to perform pass/fail testing.
2. Use remote commands to read back test data from the
spectrum analyzer.
1. Limt line editing and Pass/Fail testing.
The upper and lower limit lines apply throughout the entire
frequency span. The limit lines can be used to detect if the
signal amplitude is above or below a set amplitude level. The
judgment of the pass/fail test is shown on the bottom of the
screen.
To create a limit line, edit the ten points in the lower Limit Line
Editing Table, shown below.
