with wavelength, turning Wavelength Compensation on may cause a rescale of the
available ranges. If this occurs, the instrument will set itself to the same currently set
range if it is still available. If it is not, the instrument will set itself to the next available
range.
Trigger Level Tracking
Turns Trigger Level Tracking On. This applies to Internal Trigger Mode only.
Since the Mach 6 uses a hardware trigger, and the pulse that creates the trigger exhibits a
DC drift proportional to average power, the trigger level will appear to shift in relation to
the pulse as the. At low duty cycle, the pulse baseline will be stable and triggers will
occur as intended. With high duty cycles the pulse will drift negative. If this drift is
greater than the set trigger level the instrument will stop triggering and miss pulses. To
prevent this, the trigger level must be corrected as the pulse baseline drifts. Trigger
Tracking monitors the DC level of the pulse and modifies the trigger level so it remains at
the set level in relation to the pulse. When triggering stops or Mach 6 is disarmed, or
trigger tracking is turned off, the trigger level returns to its unmodified state.
Test Pulse Memory
Tests the internal instrument pulse storage memory and returns the result. Note that
testing the pulse storage memory is destructive of any pulse data currently stored.
Clear Pulse Memory
Clears the internal instrument pulse storage memory. Note that clearing the pulse storage
memory is destructive of any pulse data currently stored.
Query Number Stored
Returns the number of pulses currently stored in the pulse memory.
Auto Read Batch
If this box is checked, then after a data batch is taken it will be automatically directed to a
data file, to the displays, or both depending on the state of the Read to File and Read to
Displays check boxes.
If there is no currently open data file, you will be prompted to select one. Subsequent
files will be auto incremented.
Read to File
Sets the target for any pulses read from instrument memory to a text file. If a data file is
currently open then it will be used. If there is no file open, the user will be prompted to
select or create a file. Data is stored in the following format:
