| Oslaw:
What are the alternatives to an Oscilloscope when you cannot afford one yet? |
| dzseki:
I guess it depends what feature dou you want to use of the oscilloscope? Also older analog oscilloscopes can be obtained for near free these days. |
| Gyro:
It depends what sort of things you are doing. Also when you say "cannot afford", maybe quantify what you can afford - there are some very cheap options these days (in increasing price order): If you're only doing simple digital stuff: - Build yourself a logic probe with pulse capture option (<$1) - Buy a low cost 8 bit USB logic analyser clone (Saleae compatible) and use it with Sigrok pulseview s/w (<$10) If you're doing analogue stuff: - Buy a single channel 'pocket' scope such as the DSO150 clone (<$15) - Buy a Hantek 6022BE 2 channel USB scope and use the improved s/w in the forum 6022BE thread (~$50) - Buy an OWON VDS1022(preferably I version) 2 channel USB scope (~$50-70) Note, that the above options give you increased capability with increasing price (obviously). I have stayed well below $100, hopefully there's something there that you can afford. Other options are a lucky find analogue scope on ebay (risky if not 100% working and you're inexperienced) or ask if some kindly local forum member has something low performance that they will part with for little money. Hamfests are another possible source. There really isn't much of an alternative to a scope if you don't have one, unless you're doing very low frequency or DC stuff where you can get by with a DMM. P.S. Set your country flag so that people know where in the world you are - shipping probably costs more than price for a second-hand scope. |

You may also look at the 3-4us$ frequency counter kits. If you can stretch your budget to 100us$, you can look at a Hantek 2C42 or Mustool MDS8207. |
| Gyro:
Once I reached >$50 I'd certainly be looking for 2 channels, the Mustool fails that test. Screen size/resolution is also an issue with handhelds. |
