I was not sending a terminator at the end of the command and I had automatic read after send turned on. Setting to manual read, sending <CR> and then reading manually stopped the strange behavior. With a few lines of BASIC I'm now saving frequency readings to a file. I've already found that my home-built adapter won't work with Timelab. It has served it's purpose. With less than $10 worth of parts I was able to verify that the GPIB on my HP5335A is working. Now it's time to get a better GPIB adapter. I like the Prologix because It's easy for me to write code to access a com port. Do you know if the 82357 type adapters can be accessed as a com port? Any suggestions on what adapter to use? _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
