Trace Buffer - Keysight B2980B Series User Manual

Trace Buffer

The trace buffer collects the test result data until a full buffer is detected. The
maximum data size is 100,000 blocks. The data flow is shown in
data block may contain multiple data, such as current measurement data, charge
measurement data, voltage measurement data, resistance measurement data,
voltage source output data, calculation result data, limit test data, time data,
temperature data, humidity data, and status data. They are selected by using the
Format keys of the I/O key group. See
