USB cable of APPA 500 Series based meters: APPA IC-300U
By the datasheet and feature list it seems to be that APPA 208 is the bench version of the APPA 506 handheld meters. Extra features of the 208 compared to the 506: AC 100-240V power supply (but it can still run on batteries), higher frequency measurement range at higher precision (4 MHz), duty cycle measurement and an extra button for display light instead of the automatic light sensor of the 506.
Important: Some of the older models of the Series 503/505, like the Voltcraft VC-950, don't support the new APPA communication protocol with model identification. For these devices you need to manually select the appropriate driver (voltcraft-vc950, appa-500-legacy, etc.) in sigrok manually.
