Hello ! I have a 2601B, I want to use the pulse generator to generate a trigger signal, 2601B receives the trigger signal through the digital I / O interface, and then generates a pulse output in smua. Now the running program 2601B can not output the specified voltage. I don 't know if this is a code problem or a connection problem. Attachment is code. I have some questions to understand : 1.Use digio to receive the trigger signal, how the bnc line should be connected to the digio; 2.Using a pulse generator to generate a trigger signal, how to set the signal strength, time, type ( adjustable or TTL / CMOS ), active high or low; 3, Does Digio need impedance when receiving the trigger signal, if necessary, what are the requirements.
