Limits Channels Controls: Spectrum Dialog >> Limits >> Left, Right In
Spectrum Limits tests can be applied to either or both input channels by toggling the Left In and/or Right In buttons. Both channels use the same Max and Min limits curves, so both must be calibrated with compatible units. If both Left In and Right In buttons are selected here, then if one channel has the SPL button active in its User Line dialog, the other must also. If both buttons are selected (and both Input channels are active and selected for display), the Y axis is shown for the Left input range, and the Max and Min limits curves are displayed appropriately for that channel. If the Right input has a different sensitivity, its trace will not match the Y axis or the Max and Min curves, but the Limits tests will still function properly for both channels. If you toggle either channel display off, the Y axis and Max/Min curves will be shown for the remaining selected input. The Limits tests continue to work regardless of the channel display state. Note: If both inputs are active (so the Y axis shows the Left input range) but only Right In is selected in Limits, no limits curves are shown. You must de-select the Left In display so the Y axis shows the Right input range. NOTE: These buttons are disabled after the trial period, unless a Professional license key is present. Macro Notes: LimitsL=1 applies Limits to the Left Input, LimitsL=0 removes them, and LimitsL=x toggles the current state. Similarly, LimitsR controls the application of Limits to the Right Input.
