will not return to its lower level after the strong signal stops.
Setting the Analyzer Input Gain
Normally the E7495A/B is set to add the most gain in the receive path to boost
low-level signals. If the signal is high, there is no reason to add gain. When you’re
measuring a strong signal, select
Low sensitivity to reduce the gain in the receive
path and lower the noise floor. For a low level signal, select
High.
NOTE The Sensitivity setting is coupled to the Noise Correction setting. Changing the
Sensitivity setting from
Low to High will cause the Noise Correction setting to
change from
On to Off. Conversely, if the Noise Correction setting is changed from
Off to On, the Sensitivity setting is changed from High to Low.
Setting Noise Correction
You can turn the Noise Correction function on or off. When set to On, noise
correction will be activated and the test set will correct for the noise generated
internally by the analyzer. It allows the you to make accurate measurements on
