Dan,

The Tek 453 has two vertical input channels. Did you connect to the one that is being displayed? Are you using a 10X probe?

Yes, you should see a square wave if you have the vertical amplitude and the horizontal sweep set correctly.

I have a question about the XG3 signal generator. I’m setting it up for some 
troubleshooting and tracing on my K2 (issues with 160 module installation) and 
I have a TEK 453 scope that I barely understand how to set up properly. I got 
the unit from the TEK museum here in Portland,OR and it was completely 
refurbished and calibrated by the guys there. The issue is that when I connect 
the XG3 to the scope (just for observation and practice before I connect it to 
the K2) it seems to be just outputting a straight line like a DC voltage. 
Shouldn’t it be showing a waveform either square or sine? I tried connecting  
it to an older scope just to check and same results. What am I missing? I’ve 
played with the scope controls by it’s quite likely I’m missing something 
obvious!
