However, given the fact that he is an EE, it's perfectly believable that he would want a cheap scope sitting around on a secondary office. Probably feels naked without one. Maybe he got the 1052 because this is a relatively insecure office in a university campus, he paid for it with his own money and knows of some past thefts. Plus, being an astronaut, he doesn't need fancy props to boost his tech cred to the audience.

the more wires they can have sticking out of it the more specialized it will appear to the common person watching. wouldnt be surprised if they just stated gluing extra probes to the buttons for a prop.
