Serviscope Video Question
Hello,
I've just watched this 1985 video from Serviscope. I am wondering what equipment is used and why between 16:26 - 16:34. The DUT looks to be connected to a plotter and is drawing something. All the gear looks like it is from Philips. Does anybody know? |

Re: Serviscope Video Question
The finger just pressed a button labeled 'trig' before the plotter ran. The sig gen was set to sweep. I rather suspect what was plotted was a frequency response shape. The plotter going right to left seems strange, but it was moving a lot faster than the knob on the generator set to a 100 second sweep would imply so that must have been the retrace that was filmed, along with a falling tone. Hope the pen was up

Re: Serviscope Video Question
Thanks for posting that video, very entertaining.
I worked with a crowd of ex Servicescope people at Granada. At least the department store engineer had room in his van for a few sets, we had Austin Metro's for a while and you could barely get a 26 inch CTV in the back. Happy days? you must be joking.
