Programmable AC Source 61501/61502/61503/61504 User’s Manual

Press
SHIFT
, then
ENTER
to go to INTERHAR execution page. The LCD shows _TRIG_ON
is under action, and * STOP * is the triggering status at present. Fi is the sweeping
frequency. (Fi = 0 means no sweeping wave superimpose on original fundamental output.)
Press
ENTER
to trigger. Then LCD shows status * RUNNING * and TRIG_OFF and
TRIG_PAUSE. Press
or
to move cursor and press
ENTER
to select. TRIG_OFF is
to stop the INTERHAR waveform. TRIG_PAUSE is to pause the INTERHAR waveform in
certain frequency. The frequency will continue to sweep when users move cursor to
TRIG_CONTINUE and press
ENTER
. The LCD shows * FINISH * when the sweeping
frequency reaches to Fi_end.
If the AC Source is in output status, press OUT/QUIT , the output will quit to zero voltage.
Then, if press OUT/QUIT again, the AC source only out the waveform set in MAIN PAGE.
Users must press ENTER to trigger again. Or if in quit status, users can press ENTER to
output interharmonics waveform directly.
The INTERHAR waveform will shut down when press
PAGE/EXIT to exit INTERHAR
execution page.
For practical use and to protect the power stage of AC source, the
LEVEL has to be restricted relate to Fi_start and Fi_end :
If 0.01Hz <
Fi_start or Fi_end < 500Hz, LEVEL < 30%.
If 500Hz < Fi_start or Fi_end <
1000Hz, LEVEL < 20%.
If 1000Hz < Fi_start or Fi_end <
2400Hz, LEVEL < 10%.
