Quick and dirty instructions for basic frequency measurements with my TI app (lacking any other documentation): - Install the adapter and its drivers - Install http://www.ke5fx.com/gpib/setup.exe (5 MB, requires Win2K or later) - Set your counter to talk-only mode and set up a measurement that will generate frequency or TI readings at something less than the counter's full rate. I recommend starting with frequency readings at one per second to keep things simple while debugging the connection. - Run the Prologix configurator in my package and select the virtual COM port for your adapter. At this point you should see the counter readings scrolling by in the TTY window. - Hit 'Update CONNECT.INI' and exit the Prologix configurator - Run the time-interval analysis app - Select "Acquire->Acquire from GPIB counter in talk-only mode" You should see the same readings in the 'Incoming Data' window that you saw earlier. - Assuming you're looking at frequency readings, select 'Frequency (Hz)' and enter any necessary values in the 'Numeric Field #' and multiplier fields to scale your counter's readings to Hz units. - Hit 'Start Measurement'. It should begin plotting frequency, phase, and ADEV, etc. readings. Initially, you should hit the 'f' key (Measurement->Frequency difference) and make sure the values being plotted make sense. In 'f' mode, the 1-second row in the frequency chart should match the counter's display exactly, apart from any floating-point rounding error in the LSDs. Once you get to this point, you are up and running. I've never used a 5335A with the program, but the talk-only acquisition option should work with almost any model counter. If you try it and have problems getting these steps to work, let me know (offline so as not to clutter up the list) and we'll figure it out! -- john, KE5FX _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
