Step 4 Configure for burst of high speed readings
There are two data acquisition modes, normal and burst. The
burst reading rate is 2000 readings/sec into the buffer (plus
post-processing time of the raw readings, typically 2msec/
reading). To achieve this speed, certain tradeoffs are made
with flexibility, as listed in
1. To continue the reading storage example with burst
mode selected, display the CONFIG DATA STORE
menu by pressing the CONFIG key, then the STORE
key:
CONFIG DATA STORE
BURST-MODE DATA-GROUP CONTROL
CLEAR-ALL COUNT FEED
2. Select BURST-MODE and press ENTER. After a
momentary message about clearing the buffer, the
display shows:
BURST MODE
OFF ON
3. Select ON and press ENTER. (Certain instrument
parameters are saved when burst is enabled, and are
restored when burst is disabled. See
further details on burst mode.)
