in.
For manual range selection, the optimum range can be found by first selecting
the autorange function and following the procedure above. Once this range is
identified it can be set as the fixed range.
Infinite Pulse Chains:
For infinite pulse chains “Setup / Pulse Offset” has to be set to “Static”. The
offset has to be measured explicitly with pulse signal removed (menu “Offset”).
“Setup” / “Puls
-
Meas.
-
Time” should be set to a multiple of the pulse period (=
1/frequency). If the pulse period is not known, “Puls
-
Meas.
-
Time” should be set
as long as possible (more then 100 pulses should be covered by the measure-
ment window) to get a stable measurement result.
