Status of the electronic instruments

Discussion

I would like to talk about the instrument for the electronic benches , I spent some time yesterday testing the scopes and out of 5 scopes (I’m going by memory , I forgot to take note of them) present only 2 works properly , 2 need some attention and one is dead , we have 2 function generators , both working , a frequency analyser and a audio signal analyser , different (5?) Power supply (not tested yet) .

On all the instrument tested I left a note on some tape in case I found some problems.

So, we got enough scopes , I guess , and enough power supply (even too much imho) , what about the others that need some TLC? Pulling apart and analogue scope, clean it or repair it is not a day job, and we don’t really have the instruments to calibrate them , any idea?

We don’t need traceable cal we only need to trust them , a good oxo or radio 4 LW and a good voltage reference shood be ok

You should be able to transfer the calibration from the Rigol for some stuff because thats less than a year old and is calibrated.
