Standard Path
This path gives the best remote-control throughput, minimizes acoustic noise from switching and
minimizes the risk of wear in the hardware switches, particularly in remote test scenarios where both low
band and high band setups will follow in rapid succession.
In this path, the bypass of the low band/high band switch and microwave preamp is never activated,
which can cause some noise degradation but preserves the life of the bypass switch.

:POW:MW:PATH LNP Enables the Low Noise path
If a Presel Center is performed, the analyzer will momentarily switch to the
Standard Path, regardless of the setting of
The DC Block will always be switched in when the low noise path is switched
in, to protect succeeding circuitry from DC. Note that this does not mean
"when the low noise path is enabled" but when, based on the Low Noise Path
rules, the path is actually switched in. This can happen when the selection is
Low Noise Path Enable . In the case where the DC Block is switched in the
analyzer is now AC coupled. However, if the user has selected DC coupling,
the UI will still behave as though it were DC coupled, including all
annunciation, warnings, status bits, and responses to SCPI queries. This is
because, based on other settings, the analyzer could switch out the low noise
path at any time and hence go back to being DC coupled.
Alignment switching ignores the settings in this menu, and restores them
when finished.
