7104 internal switch
|
Hi Gary , my pdf of the 7104 manual has a brief description . The switch is used to determine the Z-axis control source when in Z-Y mode as it states that at least one timebase needs to be present even in X-Y mode . I have never used the scope in that way so I cannot shed any light on the effect of using it .

Hi Gary , me again . I've checked the manual? , page 3-23 refers to a switch on the logic board , thats the one , it is marked on the pcb in my scope 'in' and 'out' -- the manual says the normal position is 'in' so that the Z-axis is controlled by a timebase .

Brian: I have the PDF manual for my 7104. I went to page 3-23 and I found
no mention of switch S4488. There is no writing next to the switch on my A13 Logic Board. When looking directly at the switch, which position is "In" and which is "Out"? Is the default position near the side of the scope or near the middle of the scope? Thanx for your assistance.

Thanx for all the great help. I wish my manual allowed a Find feature. The switch was in the wrong position. Now I am in good shape. Gary

Does anyone know what this switch is used for?S4488 XY Z axis selector Switch position closest to board edge: XY timebase controlled Z axis position furthest from board edge, XY DC controlled Z axis. Timebase controlled seems to allow the timebase to blank/unblank the beam, and DC controlled allows the external Z axis input to operate. Likely, unless you want an external input, you'd likely want the XY timebase controlled input. Harvey |
