Does anyone have any idea how much these Tektronix 2712 things cost new?

Not a whole lot.  They were aimed at the CATV and broadcast service industries, so they were more economical than the 49x/275x/279x models that Tek was selling at the same time.   A 2710 was $8K in 1990, while the 495P was $29K with similar frequency coverage.

Edit: looks like the 2712 was priced at $11,950 in the 1994 catalog, and the 2795 was $22,900.

Thanks, I couldn't find any catalogue type docs on google.

TekWiki is a great site for the older catalogs (and lots of other stuff as well.)

The 2712 is an economy analyzer, about 2 grades below the 8562A.  It's still a good SA to have in the lab, and will work really well for a whole lot of applications.

Dear, I've invented and built a sensor in 2018 plus I have designed some new voltage probes, so I need a spectrum analyzer to check the linearity (HD2, HD3, THD and the noise) and AC response of the sensor and probes and publish the results in a journal, unfortunately I haven't accessed to a Spectrum Analyzer yet, I found Tektronix 2712 as an affordable choise , is it a good choise? display dynamic range is only 80dBm but I think I can use internal attenuator to see the fundamental frequency peak and the noise floor at the same time, there are some other spectrum analyzer such as RF Explorer wsub1g+ and Anritsu Ms2711 (b or d models), Advantest R4131, but I found other models are too expensive for me! What do you think abou Rigol DSA705?
I have a 16Bits Siglent SDG2042x signal generator.
