Description

For the TDECQ operator, turns on the Low-SNR mode that allows the operator to operate when large amounts of noise is present. This is equivalent to setting the Low-SNR Measurement Mode setting in the Advanced tab of the TDECQ Reference Equalizer Setup dialog. The default state of this setting is ON. This capability is activated by the L-RND or L-MFG package licenses.

If the Precision Timebase (PTB) is on, a questionable status mark (?) is placed on the measurement results. It is recommended that the Precision Timebase (PTB) be turned off when Low-SNR is enabled.

For Reference Rx operator, what function do I send this command to?

If the TDECQ equalizer is a secondary function to the Reference Rx operator, address the :SPRocess:TEQualizer:LSNR command to the Reference Rx function as identified in the following Reference Rx Setup dialog's operator diagram. In the following figure, this would be Function 2 and the command would be:

:SPRocess2:TEQualizer:LSNR
