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
location 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 symbol precedes the timestamp value. Regardless of which timestamp is
selected, the first reading 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 8 of the Model 6430 SourceMeter Instruc-
tion Manual.
