Dependencies Preamp is not available on all hardware platforms. If the preamp is not present or is unlicensed, the
key is not shown.
The preamp is not available when the electronic/soft attenuator is enabled.
Couplings The act of connecting the U7227A USB Preamplifier to one of the analyzer’s USB ports will cause
the Internal Preamp to be switched on. When this happens an informational message will be
generated: “Internal Preamp turned on for optimal operation with USB Preamp.” Note that if the
Internal Preamp was already on, there will be no change to the setting, but if it was Off it will be
switched On, to Full Range.
Note that this same action occurs when the SA mode is selected while the USB Preamp is
connected to one of the analyzer’s USB ports, if it is the first time that the SA mode has run since
powerup, or if the last time the SA mode was running the USB Preamp was NOT connected.
Subsequently disconnecting the USB Preamp from USB does not change the Internal Preamp setting
nor restore the previous setting.
