Re: Readings from 436A power meter using 82357B USB-GPIB?
|
Hello,
Some more findings... It seems like my Arduino can talk to the instrument after all. Pulling REN low (active) makes it listen to commands sent to its listen address.? However, with the REN (remote enable) active, it _won't_ return any readings! Releasing REN, I get readouts again...
Can it be that the 82357B keeps the REN line low the whole time it has the instrument addressed? If so, anyone can hint me how to pull it high when I want to read from the instrument?
Thanks to the code in the Arduino project (again, thanks to Emanuele Girlando!) I'm fairly sure what sequence to send (control lines). Anyone know how this can be bit-banged (for example) on the 82357B? The Interactive IO does not give many options unfortunately.
Regards, ? Staffan ? Staffan

Maybe I missed you saying so, but with the Keysight IOLibraries installed the 82357A/B should be essentially transparent to you. Connection Expert will let you assign it a name such as GPIB0 and then you just send commands to the 436's address.
I don't recall the exact details but there is a box to check to use 488.2 vintage protocol but that's about it. Unless there is something amiss with it, I doubt that the adapter is the problem. Since it appears to be at least sending commands, that doesn't seem likely.
