How does the Tek 24XX-Series compare to the analog PM308X/9X Series?
In the latest development of analog oscilloscopes, measurement functions were added and others functions as calibration, settings memory and autoset.
This has cost analog oscilloscope one greatest advantage he still has today: simplicity of use.
This is in my opinion the weak point of Tek 24xx and even more of PM308x / 9x.
At the time they were designed, the benefits were worth it, but now, not anymore.
These benefits are now available on all DSO, even low end, with a lot more performance.
If you need these functions, use a DSO, not a CRO !
Therefore, I would like to correct what Dave said : 24xx Tektronix
were the best portable analog oscilloscopes, but currently they are no longer because what we can now expect from a CRO has changed.
The Tek 24xx and PM308x/9x have lost the simplicity, both in use and at the level of circuit design and repair.
For this reason, it would not be my choise if I had to buy an analog scope now.
I would prefer:
Tektronix 465B or 2235(A)
HP1740A
Hameg HM605
Tek24xx are 2+2 channels and PM3094 is (true) 4 channels.
