6.11.2 PERFORMING A HARMONIC SWEEP
1. STOP the Generator, Analyzer and Sweep.
2. Use the GENERATOR MENU keys to set the required fundamental frequency.
3. Set up the Analyzer Menu. Any Harmonic number entered, other than 1, will be
over-ridden by the Harmonic Sweep command.
4. Press SWEEP START/CONTINUE to obtain the soft key titles. The Sweep Status
will remain at STOP.
5. Press the HARMONIC soft key. The Sweep Status will change to IDLE, i.e. ready to
start.
6. Press ANALYZER RECYCLE if all 16 harmonics are to be scanned as the result of
one command, or ANALYZER SINGLE if the measurement at each harmonic is to be
initiated manually.
7. Press GENERATOR START. If RECYCLE has been enabled, the complete sweep
will now be carried out.
If SINGLE has been enabled, the Display will now change to show the result of the
measurement at the fundamental frequency.
Each time the SINGLE key is pressed, a new reading will be displayed, showing the
response at each successive harmonic frequency.
6.11.3 ERROR 21
If ERROR 21 is displayed, the limit of 65 kHz has been reached before completion of
sweep.
6.11.4 SWEEP TERMINATION CONDITIONS
If, on ANALYZER RECYCLE, the sweep is completed normally, or is terminated due to
the Error 21 condition, the Analyzers will be left set to Harmonic 1, i.e. the fundamental
frequency. However, if the sweep is not completed, e.g. is stopped by pressing SWEEP
STOP or SWEEP HOLD, or is only stepped part way through by using ANALYZER
SINGLE, the Analyzers will be left set to the last harmonic measured.
If the latter condition is not required, the Analyzers can be returned to the Harmonic 1
state by entering a "1" in the [ANALYZER COMMON] Menu in the HARMONIC position.
INITialising and RESETting have the same effect, but also return all the other
parameters to their default values.
