Hello, I’ve been waiting to buy a decent oscilloscope for a while now and I have found a store with the following used ones in stock. Any info/recommendations on why to choose one over the other would be appreciated.

I don’t have a specific feature I am looking for but I do want to optimize bang/buck.

Yokogawa DL1740EL
Iwatsu DS-5624A
Tektronica TBS2204B


Thanks in advance!

well you are in some of them  "oldies"

you have to check  for servicing or parts availability,   for me i would go to the TEK,  and be sure they all pass self tests and have a proof of that

i ask the seller to put his avatar name in the self test screen and screenshot picture, if not   i move away

you have some threads for the tds2k 3k series ...

Yokogawa ?  there is a few

Iwatsu ?

Only the Yokogawa DL1740EL is an older model (but 500MHz). The others are relatively new. Unless 500MHz is needed, I'd leave the DL1740EL at the shop. The DL1740EL is a nice compact oscilloscope (I have owned one) but the others have nicer displays and an easier user interface. Also the analog fronted gets rather hot and the implemented cooling solution is quite bad. In the one I had, some of the pre-amplifier chips where replaced and one needed replacing again. Based on specs the Iwatsu DS-5624A might be the most versatile one.

The Tektronix TBS2204B can't be compared with the TDS2k or TDS3k series. The TBS2204B is aimed at educational / repair shop work. Simple, but effective. A customer one mine has a TBS2000A series and everyone prefers to use that one instead of the Rigol and other cheap scopes that are around the lab.

Ah appreciate the info! So I can get the Iwatsu for ~1300 while the Tek is around ~2500. Is there anything on the Tek that might make it worth that much more?

I’ll talk to the shop owner and see if he can run the self test before buy.

No expert, but you may want to check the prices on new comparable scopes from e.g. Siglent or Rigol.
