I have an E4436B signal generator and its UND card had been poorly serviced. The capacitors in reconstruction filters (most likely 250 kHz) were removed and placed on different pads. It resulted in having the "unlevel" error when setting the spacing of multi-tone to below approx. 6 kHz. In order to repair the filters, a CLIP (schematics) is needed for the UND card. However, artekmedia does not carry CLIP for ESG-D series, and I was hoping the members of this forum could help me find the needed CLIP. Thank you!
