5.6 Additional Information On Memory

The MicroTrap™ has a large circular memory containing 4,194,000
data points (doubled with optional memory upgrade) that are
allocated across each of the tests into which the
has been divided. The total number of tests and selected recording
rate dictate the total record time available for each test. Selection of
the number of tests to be recorded and the Recording Rate is done
using the MREL Data Acquisition
The MicroTrap™ Software automatically calculates and displays the
Total Recording Time per Test and the Pre-Trigger Time. Notice that
the graphic shown is for a MicroTrap™
Memory Upgrade installed.
For those Operators with additional interest in recording times:
A general equation to calculate the Total Recording Time (Pre-trigger Time + Post-trigger Time) is:
Total Recording Time (seconds) = 4,194,000/((# of tests)x(# of channels)x(recording rate))
If the number of tests selected is one, and only one channel is being recorded, the available recording time will be maximized for a given
Recording Rate. For example, at the maximum Recording Rate 1 MHz, the Total Recording Time will be:
At a slower Recording Rate of 500 kHz (for example), the
memory is divided into 4 tests and there are 4 Scope channels on and VOD is also being recorded, the
memory allocating 4,194,000 points/((4 tests)x(5 channels)) = 209,700 points per test per channel. Following the previous example, the
Total Recording Time per test can be calculated as follows:
If the Recording Rate is reduced to 500 kMHz, the Total Recording Time will become 0.42 seconds per test per channel. If these
recording times are insufficient for your testing applications, then contact
doubles the MicroTraps™ internal memory and thus doubles the
