In addition to the date/time,date format, system language, network setting and frequency reference, characteristic menus such as the LOnulling alignment, GPS positioning (optional) and power saver are available.S3302 series spectrum analyzer has the function of LO nulling alignment, which is conducive for LO null calibrationwhen required. To accurately measure the amplitude of the signal with the frequency below 5MHz, attention shouldbe paid to the zero-frequency signal. If the zero-frequency signal is above >-20dBm, LO null calibration should beperformed so as to prevent gain compression caused by too large amplitude of the zero-frequency signal.The optional GPS positioning function of S3302 series can be achieved with the external GPS antenna. The usercan view the number of current satellites in service and the longitude, latitude and altitude information. This functionis applicable to accurate positioning in fields.In the power saver mode, the spectrum analyzer will enter the sleep state in the case of no operation within thesleep time, including shutdown of the LCD, internal module power, etc. If any key is pressed again, the spectrumanalyzer will exit the sleep state and change into the normal operating mode.
