•10 MHz Out - Activates, or deactivates, the 10 MHz out signal on the rear panel of the instrument. The 10 MHz out can be used to lock other test equipment to the same frequency reference that is used by the transmitter tester. Once activated, the 10 MHz out feature is persistent, so if it is set to On it will remain on, even if the instrument has been preset, or powered off and then on

•IF Align - Select to view the IF alignment signal. This signal is available as a diagnostic function, to check the operation of the alignment signal in the case of alignment failure. Once selected, a menu accessing the IF alignment signal parameters is available at the bottom of the Input menu. Either CW, comb, or pulse signals may be selected. Because the alignment signal is input at the IF frequency, it is displayed on any active Spectrum Freq Domain window, regardless of center frequency
