Issues

According to KE5FX:

Unless they've had their cables replaced, they had a whisker- or dendrite-growth problem in the cable that will short out the signal and drive you nuts. It can be cleared by running some current through the BNC connector but only temporarily. The only fix is to order a new cable from Tektronix, which I'm not sure you can still do.
