Features to enhance DUT testing

Data store

The data store (buffer) can store from 1 to 2500 readings, and provides statistical data on the
stored readings.
Storing readings
To store readings, press STORE, key in the number of readings to store, and press ENTER.
The star (*) annunciator indicates that the buffer is enabled. To start the storage process, turn
the output on and (if necessary) trigger the unit. The star (*) annunciator turns off after storage
is completed.
Recalling readings
To recall readings, press the RECALL key. The buffer location number is the memory loca-
tion of the recalled reading. Location #0000 indicates that the displayed reading is stored at the
first memory location. To display other stored readings, use the edit keys to change the buffer
location number. To exit from the recall mode, press EXIT.
Timestamp — Just below the buffer location number is the timestamp (in seconds) for the
reading. It can be referenced to the first reading stored in the buffer (absolute timestamp), or it
can indicate the time between buffer readings (delta timestamp). If the absolute timestamp is
selected, the @ symbol precedes the timestamp value. If the delta timestamp is selected, the δ
symbol precedes the timestamp value. Regardless of which timestamp is selected, the first read-
ing is always timestamped at zero seconds.
To change the timestamp, exit from the recall mode and use the following menu sequence:
Press CONFIG > press STORE > select ABSOLUTE or DELTA
NOTE While in the recall mode, buffer statistics (minimum, maximum, peak-to-peak, aver-
age and standard deviation) can be displayed using the TOGGLE key. Details about
buffer statistics are provided in Section 9 of the 2400 Series SourceMeter User's
Manual.
