Title: Tektronix 7854 horizontal adjustment
Post by: little nellie on November 23, 2019, 03:46:13 am
Hi, is there a way to adjust the horizontal position in the 'store' mode? I am able to adjust the horizontal position in the 'scope' mode with the timebase. But when switched to 'store' the display is shifted left about 1/8", unable to locate any knobs for adjustment in that mode.  thanks

The service manual includes all of the details for the rather involved display calibration procedure.  There are trimmer potentiometers to adjust position and scaling of both the analog and storage display elements so that they align with the graticule and align with each other.
