Hello there!
I recently got hold of some R&S test equipment. The equipment isn't in good working condition, so it needs some repairs. For proper repairs, I need the service manuals for these devices.
They are from the '70s. I attached an image of the test equipment. It consists of a rack-holder called MSU, that holds the EZK, EZP and the test receiver ESU2.
Yes, I already contacted the R&S company itself. I obtained datasheets and operating manuals for all of the devices (MSU EZK EZP ESU2), and a service manual only for the EZP.
I really need a service manual for the ESU2, because that's the instrument that has the most problems (it only has a problem in the signal attenuation stage and a relay that keeps clicking every 2 seconds). And maybe for the EZK, it works okay, but it's good practice to have your equipment properly documented.
Do you know where I can find service manuals for these old devices? Or maybe you know someone who has the ESU2 and can scan/already has scanned the service manual?
Or maybe you know something about these devices? Feel free to express your thoughts!
Thanks! Looking forward to your replies.
