Input Selection Keys
The Input Selection keys (to the left and right of the GEN button)
control which channel is being measured by the analyzer, and whether
the signal comes from the analyzer inputs or the internal
generator-monitor (gen-mon) path. The gen-mon path provides a
direct connection from the generator to the analyzer for reference
measurements.
Most measurement functions only use a single signal source (channel).
For these measurements, pressing the INPUT A button will cause the
measurement to be taken from the analyzer input A. Pressing the
INPUT B button will cause the measurement to be taken from input B.
Pressing the center GEN button after selecting the channel to measure
will connect the analyzer to the internal gen-mon path.
Some functions (such as the Level function) require two input sources
(channels). For these functions, the opposite channel is automatically
selected for the secondary measurement when INPUT A or INPUT B is
pressed. Pressing the GEN button once will connect the primary
measurement to the internal gen-mon path.
When the internal gen-mon paths are used, the front-panel generator
outputs are still connected to the generator. Signals may still exist on
the output connectors, and the analyzer measurement may be affected
by loading or interference on the generator output connectors.
FUNCTION Keys
The FUNCTION keys (marked on Figure 3-1) select the particular
measurement to be obtained and displayed. This affects both the
displayed measurement and the internal configuration of the
instrument. Pressing any function key will configure the instrument for
that measurement function and display the results of the measurement.
Some FUNCTION buttons choose two different measurement
functions. The first measurement is selected by the first press on the
FUNCTION button, and the second is selected with a second press.
