JUNTEK PSG9080 80MHz DDS Function Generator Review - No.764
I review the JUNTEK PSG9080 DDS Programmable Signal Generator.
PSG9080 on Aliexpress store: https://defs.link/?u=468090
JUNTEK site: http://junteks.com/product/278017415
This was supplied to me at no cost for the purpose of review by JUNTEK.
I go through the menus systems and take a look at the PSG9080 features, I then hook up to some of my test gear and check its output level linearity and output frequency accuracy.
I then do a teardown and do some more electrical testing for things such as the BNC connector earthing, rear panel earthing, internal power supply voltage, rear power socket connection, and obviously have a close look at the PCB's.

40:52 - Teardown.
43:16 - Checking the earthing system and for BNC earthing.
46:21 - Identifying power supply voltage and connections.
47:38 - Checking for phantom voltages on BNC connectors.
48:54 - Earthing the BNC connectors.
49:17 - Close look at the PCB's.
