The System Events tab on the System Event Log menu (on page 2-34) displays the following buffer
events:
• Event code 4917, "The fill status of bufferVar is 0% filled"
• Event code 4918, "Reading buffer bufferVar is 100% filled"
• Event code 4915, "Attempting to store past the capacity of reading buffer," which occurs when a
buffer that is set to fill once fills.

Creating buffers
To create a new user-defined reading buffer, you need to provide a name and capacity for the new
buffer.
User-defined buffer names must start with an alphabetic character. The names cannot contain any
periods or the underscore (_) character.
There is no fixed limit on the number of user-defined reading buffers you can create. However, you
are limited by available memory in the instrument and the overall total capacity of all the buffers
stored in the instrument cannot exceed 1,000,000 readings.
The following topics provide information about using the front panel to create buffers and introduce
how to use remote commands to create buffers.
The instrument automatically selects the reading buffer you just created as the buffer in which to
store front-panel readings.
