Hi,
 
As I'm new to electronics, I do not know how to test a logic analyzer. I bought a used 'Meguro' logic analyzer and it does not comes with user guide and the neccessary cables. I think the cable is just normal cable (eg. Hard-disk flat cable) and a test pin attached at the end of it.
 
The unit performed the self-test successfully upon powered up but, someone told me that does not mean the logic analyzer is working. If anyone can teach me how to test it, that will be great.
 
My logic analyzer (model: MLA-3300) has the following connectors/ switches behind the box.
- Check (looks like a headphone socket)
- VAR Adj Threshhold (looks like a POT)
- VAR <-> TTL (switch)
- DC Input (socket). Not sure why it is there since it allows AC input.
- AC socket
 
On its side, there is a 20 Pins male connector. I've made a cable using those hard-disk colored flat cable. On one end, I attached the cable to a 20 pins (female) connector and at the other end, I soldered test clips (different colored; spring type) to each strand of the cable.

Thanks in advance for the help.
 
cheers,
Davis
