Mach 6 User’s Manual Revision 2.1 44
The response of the probe is stored in the probe memory and is read when the Mach 6 is
powered on. It is plotted on the Probe Data display
Temperature Correction
Temperature correction is done in the Mach 6 Application Software. When a temperature
different from the calibration value is selected, the software computes the correction
factor based on the responsivity temperature coefficient and the variation form the
calibration value. Since temperature induced variations are typically a few percent or less,
no gain rescaling is needed to adequately compensate the measurements.
Pulse Memory
Mach 6 contains an internal memory for storing measured pulse data. Due to the high
repetition rate that Mach 6 can measure, there is no real time display. Data is retrieved
from pulse memory after it has been acquired and displayed using the Applications
Software. The internal memory can be read to either the displays, to a file, or both.
Reading the pulse memory does not remove the data from the memory. The same data
can be read multiple times if desired. Data will be lost if:
1. The memory is tested. The memory test writes patterns to the pulse memory and
then verifies those patterns. Any stored test data will be overwritten. Requesting a
memory test will cause the software to prompt the user to ensure this is the
intended action.
2. The memory is cleared. The memory clear writes zeros to the pulse memory. Any
stored test data will be overwritten. Requesting a memory clear will cause the
software to prompt the user to ensure this is the intended action.
3. The Mach 6 is powered down. The pulse memory is SDRAM and is a volatile
memory.
File Management
After data has been acquired, it may be saved to an external file for later analysis, either
by the Applications Software or some other software package of the users’ choice. The
Applications Software can open, close, and copy an open file to the Applications
Software displays.
Obtaining Help
There is context sensitive help available by selecting the Show Context Help item in the
help menu. A help window will appear when the mouse cursor is placed over a control or
indicator.
There is a compiled help file that can be called by selecting the Help item in the help
menu.
