Error message Cause or corrective measures
WARNING 001
Combined frequency and duty set the pulse width to not more than
25 ns and the pulse may be lost.
WARNING 002 Combined frequency and duty set the pulse width to 25 and 100 ns
and pulse width may be unstable (large jitter component).
WARNING 003 Since high frequency, burst oscillation mark and space may be
unstable.
WARNING 004 Low level setting changed due to high level setting change, or
conversely, high level setting changed due to low level setting
change.
WARNING 005 Changed to simple standard units (Hz, s, Vp-p, V).
WARNING 006 Since combined period and pulse width exceed the permissible
duty setting range, pulse width was changed in order to enter the
permissible duty range.
WARNING 015 Because of DUTY VALID change, the duty was changed to
0.01% or 99.99%.
WARNING 016
Because of a mode change, DUTY VALID was changed to
IMMED.
