GPIB-USB 82357A interface (agilent) py82357A-0.4 release

Some instruments allow for sending the measured data in binary form. It assumes a normal string with comma- or whitespace-separated values.

PyVISA expects a file called visa Contact an Expert Chat Live. No, the A USB cable is attached to the converter for a more robust connection. It is independent of a particular bus system, i. I recommend to import the VISA functions with: The class Instrument defines the following methods and attributes: Since only labbiew instrument can be connected with one serial interface, there is no double colon parameter.

Either copy it there or expand your PATH. Where can I find manuals for discontinued and obsolete Hewlett-Packard, Agilent and Keysight test equipment? It bases on earlier experiences by Thalhammer.

Each chunk is 20 kilobytes long by default. You just have to append the lines keithley. Does the A support USB hubs?

You are strongly encouraged to switch to the new implementation. First, we have to initialise the instrument: The general keyword arguments are interpreted the same as with the class Instrument. By the way, if you use Windows, I recommend to install Enthought Python. Just start the program with from 8257a.

About the legacy visa module — PyVISA documentation

So you could write: You will only notice the increased speed, as PyVISA converts it into the same list of values as before. This section is a reference to the functions and classes of the visa module, which is the main module of the PyVISA package.

My A isn’t working correctly, where can I find more information? See section A more complex example above.

Okay, now the instrument is prepared to do the measurement. Length of read data chunks in bytes, see section Chunk length.

The next step is to write all the measurement parameters, in particular the interval time ms and the number of labvieq 10 to the instrument.
