Operating Concepts
Lightwave Component Analyzer Operation
Front Panel System Operation
Using the front panel, you can choose a specific measurement, control the source, control how the data is
taken and displayed. The front panel keys are divided into functional groups as shown in the figure below.
Figure 5-1. Front Panel Controls
Softkeys
The function of this group of keys is not fixed but is determined prior to their use by keys in the
STIMULUS, RESPONSE, and INSTRUMENT STATE function blocks. The key labels appear on the analyzer
display.
Stimulus
This group of keys controls all functions related to the analyzer’s internal microwave source, including
output power levels and power sweep, frequency range, sweep time, and number of measurement data
points measured by the receiver. The stimulus signal modulates the lightwave source in the test set or an
E/O or E/E device.
Response
This group of keys controls all receiver functions. This includes the measurement parameters, display
format (log magnitude, phase, delay, polar), type of scale, averaging, marker functions, and measurement
calibration.
Instrument State
These keys control channel-independent system functions including instrument preset, plotter and printer
control, memory save and recall (internal or external disk), and limit testing.
