I switched on my 8601a, 8600a and the scope. I left the RF out to the scope Y input disconnected. The scope is in X-Y mode. The generator is set for a 3MHz sweep width across 50MHz. So it is sweeping from 48.5 MHz to 51.5MHz with 50.0MHz in the middle.

I set the markers across the band being swept with the center button of the marker selected and set to 49.99MHz. You will see it in the middle of the scope display as the brightest marker because the marker button is depressed.

You should see this BEFORE connected the RF.

Also a correction to my earlier instructions: Put the sweep trigger switch (lower left) to FREE. It eliminates the bright dot on the right which I believe is due to the sweep waiting for the next line trigger. Fee run is fine so long as the swwep speed when aligning is not set too high. (we can discuss that later when you get to that step).
