The KSt command (harmonic lock) limits the tuning range of the analyzer to a specific harmonic of the local
oscillator as selected by start and stop frequencies. The functions of the KSt command and the front panel (,.,
When executing a harmonic lock, use the following method to ensure the desired harmonic is selected:
1. Select desired harmonic by setting a start frequency within the desired band. (See Tuning Curves in Appendix
F for frequency range of each harmonic.)
2. Set analyzer to single sweep mode. Single sweep ensures the desired harmonic is selected when executing a
bank lock.
3. Execute KSt to lock the desired harmonic.
4. Set analyzer to continuous sweep mode.
5. Reset desired start and stop frequencies.
Remember, before you can change the frequency range to another harmonic, you must unlock the band with the
KSQ (harmonic unlock) command.
KSR (Diagnostics On) can be activated, at any time, to display the local oscillator harmonic number in the upper
left comer of the CRT display
