No! Either the PG2050 or the PkPG2116+ is only able to generate digital waveforms. 

No! The PkPG2116+ is only able to output 8-levels voltage, 5V, 3.3V, 3V, 2.8V, 2.5V, 2.1V, 1.8V, 1.5V; the PG2050 is able to output 255-levels voltage between 1.5V to 5.5V.

Yes! You may cascade more than 2x PG2050s or more than 2x PkPG2116+ by the external event trigger function. Nevertheless, each PG has its own software window.

Close the PG software, then right-click the PG software and choose “Administrator” to run the “Convert-to-waveform” function.
