Model 6517B Electrometer Reference Manual
:AUTO <b>
This command is used to control the auto buffer sizing.
Usage
:TRACe:POINts:AUTO <b>
:AUTO?
<b>
Details
This command is used to enable or disable auto buffer sizing. When enabled, the buffer size defaults
to the measure count value in the trigger model. With auto buffer enabled, changing the trigger
model's measure count value changes the buffer size to that value. If the :TRIGger:COUNt is
greater than the maximum buffer size, the buffer is adjusted to the maximum size and the following
message is displayed:
+314 "Buffer sizing error; sized to MAX" (MAX may be to 50,000 readings).
Disabling auto buffer sizing does not affect the size of the buffer. It simply means that you must then
use the :POINts command to change the buffer size.
If you use the :POINts command to change the buffer size while auto is enabled, the buffer size
changes to that value and auto buffer sizing disables.
If you try to enable auto buffer sizing while the measure count is programmed for infinite, an error
occurs and the command is ignored. You cannot have an infinite buffer size.

:ACTual?
This command is used to query the number of readings in the buffer.
Usage
:TRACe:POINts:ACTual?
Details
Description This query command returns the number of readings that are currently stored in the
buffer. After sending this command, the number of readings stored in the buffer is sent to the
computer when the Model 6517B is addressed to talk. This command can be used to monitor the
storage process.
