Creating buffers
To create a new user-defined reading buffer, you need to provide a name, capacity, and style for the
new buffer.
User-defined buffer names must start with an alphabetic character. The names cannot contain any
periods or the underscore (_) character. The name can be up to 32 characters long.
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. The overall capacity of all buffers stored in the
instrument cannot exceed 6,875,000 readings for standard reading buffers and 27,500,000 for
compact reading buffers.
When you create a reading buffer, it becomes the active buffer. If you create two reading buffers, the
last one you create becomes the active buffer.
The following topics provide information about using the front panel to create buffers and introduce
how to use remote commands to create buffers.
For additional information about using remote commands for buffer operations, see the following
sections of this manual:
• Remote buffer operation (on page 3-23)
• SCPI commands, see TRACe subsystem (on page 6-156)
• TSP commands, see TSP commands (on page 8-7)
Using the front panel to create a user-defined reading buffer:
1. Press the MENU key.
2. Under Measure, select Reading Buffers. The MANAGE READING BUFFERS window is
displayed.
