We have an 8591A that is failing the amplitude cal for the 1 kHz bandwidth (about 2dB low).

We have performed the crystal and LC bandwidth filter adjustments, but the crystal amplitude adjustment is maxed on both A11 and A13. We have swapped the A11/13 and also updated the attenuator constants. Does anyone have an idea what else may be causing this? Thank you!
