USBTMC compliance device

Normally, you should not have to use this request unless something is usbtmc wrong See Example Programs for further programming examples. Driver attributes are used to modify the behavior of the driver e.

The following attributes are available:. This setting is local to the usbtmc device.

Defines if the driver should ignore subsequent calls to its read entry point. The retries would usbtmc a timeout with instruments, so the driver simply returns 0 EOF when usbtmc for the second time.


The usbtmc is local to the current device. The value is local to the current device. Value specified usbtmc ms.

Default value: 10s. You can read this value in order to verify that your instruments are attached properly or when automatically detecting the attached instruments. You can modify usbtmc value by changing the corresponding define in usbtmc. This is a read-only attribute that returns the maximum number of USB instruments the driver can service at the same time. Note that you can do larger transfers since the driver will split large transactions into several smaller ones. This is a read-only attribute that returns the default timeout value in ms.


This usbtmc a read-only attribute that usbtmc a number indicating if the debug mode of the driver is active. I'll also have to look into whether that ought to be built into the kernel, or what Hopefully there'll be a neater solution that involves the kernel blocking a read until data is available - I'd hate to have to delay every single USBTMC command by 10msec just because a few devices are slow.

They were usbtmc adopted on December 22, Contact your device vendor for details about the device communication protocol. After plugging the scope, makes sure that you have the usbtmc stuff as in my first post: For benchtop applications, these power supplies provide a numerical keypad for direct data entry along with convenient cursors and analog style knobs to quickly make incremental voltage or current changes.
