Left Step

This control selects a Wave or Master attenuator step number.

If you are in Meter mode, this adjusts only the Left output. Measurements made on the Left channel are presumed to be the same as for the Right.

If you are in Equal Test of Match mode, the step number is set for both Left and Right attenuators.

If you are in Step Edit of Match mode, this control sets the Left attenuator, while the dB / Step control is used to adjust the Right level for a match.

It has no effect in Init Table of Match mode.
