MATH<x>:SPECTral:LOCk
Description
This command locks menus for two or more math waveforms together
as a group. The query form of this command returns an ON (1) or OFF
(0), indicating whether spectral locking is turned on. This command is
equal to selecting Spectral Setup from the Math menu, choosing the
Control tab and then clicking the Time/Track Frequency Domain Con-
trols button associated with the math waveforms that you want to lock.
However, applying spectral locking functionality from the interface is
limited to locking Math1 and Math2 (on two--channel and four--channel
instruments) or Math 3 and Math4 (on four channel instruments).

Note: Executing MATH4:SPECTral:LOCk via the GPIB interface has
no affect since there is no Math5 to which it can be locked.
