Features to enhance DUT testing
Buffer
The Model 6514 has a buffer to store from one to 2500 readings. It also stores overflow
readings and includes a timestamp. In addition, recalled data includes statistical
information (minimum, maximum, peak-to-peak, average, and standard deviation). The
buffer fills with the specified number of readings and stops. Readings are placed in the
buffer after any math operations are performed. Math operations include mX+b, percent,
or limits.
Storing readings
To store readings, press the STORE, key in the number of readings to store, and press
ENTER. The star (*) annunciator indicates that the buffer is enabled. If in the immediate
trigger mode, the storage process will start immediately. If in the external trigger mode,
each input trigger (or press of TRIG key) will store a reading. The star (*) indicator will go
off when the buffer is full.
Recalling readings
To recall readings, press the RCLL key. The message “RDG NO 1” is displayed. The arrow
annunciator () also turns on to indicate additional data is available for viewing. Use the
RANGE and cursor keys to navigate through the reading numbers, reading values,
timestamps, and buffer statistics. To return to the normal display, press EXIT.
Buffer statistics
MIN and MAX provides the minimum and maximum readings stored in the buffer.
It also indicates the buffer location of these readings.
The PK-PK (peak-to-peak) reading is the absolute value of the difference between
the MAX and MIN readings. It is calculated as follows:
Peak-to-Peak = |MAX - MIN|
Average is the mean of the buffer readings. Mean is calculated as follows:
where: X
i
is a stored reading.
n is the number of stored readings.
