Nov 29, 2022 · You may be able to resolve the timing problems with one of the following steps: changing the GPIB bus timing to the slowest setting in the GPIB Configuration Utility. The third option is less effective because it only affects the time the GPIB controller waits before valid data is on the bus and the data valid (DAV) line is asserted.

Jul 21, 2023 · If you receive all of the data and get an EABO error, then look for a particular end of string character (e.g., linefeed or carriage return) and configure the GPIB board to terminate the read on that character using the ibeos function.

Jul 23, 2008 · EABO indicates that an I/O operation has been canceled, usually due to a timeout condition after a GPIB read. Before reading from the instrument, verify that the GPIB command you are sending is understood by your device and instructs it to place data in its output buffer.

Jul 21, 2010 · Provides support for Ethernet, GPIB, serial, USB, and other types of instruments. NI-488.2. Provides support for NI GPIB controllers and NI embedded controllers with GPIB ports.

EABO indicates that an I/O operation has been canceled, usually due to a timeout condition. Other causes are calling ibstop or receiving the Device Clear message from the CIC while performing an I/O operation.

Aug 25, 2020 · so you are using a Keithley USB-2-GPIB converter: in my experience you run into problems when using those old GPIB functions. I recommend to use the most current version of the Keithley2400 driver with VISA function calls instead.

您可以有两种办法解决这个定时问题：在您的GPIB指令中加入延时，或者改变GPIB总线定时，将它设定为最慢值（在GPIB配置功能内，GPIB Configuration Utility）。 第一种方案通常可以成功解决问题，第二种方案效果可能不太好，因为它只能影响GPIB控制器的等待时间。 这段等待时间用于正确数据被放置到总线上，DAV信号有效（每次一个字节的信息被传输到设备时，GPIB需要用该信号实现握手中的一个步骤）。 最近我用新计算机更新了原先的陈旧计算机，同时我也更新 …

= EABO EABO indicates that an I/O operation has been canceled, usually due to a timeout condition after a GPIB read. Before reading from the instrument, verify that the GPIB command you are sending is understood by your device and instructs it to place data in its output buffer. For information on your device's command syntax,

Oct 25, 2020 · You can select one of three Bus Timing settings with NI-488.2 driver: 2 usec, 350 ns , and 500 ns. Complete the following steps to set the speed of the GPIB bus: This setting adjusts the source handshake T1 delay of the GPIB interface.

Sep 21, 2023 · If you receive an error on the read, it will most likely be an EABO due to timeout. If you experience this error, check the following: Verify the command you sent is valid for that instrument.
