5.1 General
Not only programming the steady sine output voltage and frequency, the AC source model
61501/61502/61503/61504 provide several powerful functions to simulate all kinds of power
line disturbance. Users can make the output change through a number of value in LIST
mode (see 5.2), or make the output change to its set value for a specific period of time in
PULSE mod
e (see 5.3), even make the output change to its set value step by step in STEP
mode (see 5.4. With these functions, it is easy to simulate such as cycle dropout, transient
spike, brow
n out, etc.
Not only measurements related to power in MAIN PAGE (see 3.3), the AC source model
61501/6150
2/61503/61504 also provide harmonic measurement up to 40 orders (see 5.5).
For modern power testin
g, the AC source allows users to compose different harmonic
components to synthesize harmonic distorted wave-shapes (see 5.6). The AC source also
can achieve
interharmonics waveform, a sweeping frequency superimposed on a static
fundamental wave (see 5.7).
5.2 List Mode
On CHOICE PAGE (see 3.4), press 5 then ENTER, choose the LIST functional list.
The waveform programming of LIST mode is the assembly of the SEQuences. The output
waveform will start from SEQ=0, then SEQ by SEQ. The execution will stop until a SEQ
which TIME or CYCLE = 0, even the following SEQs have been set will not be executed.
COUNT : the whole sequences’ executing number of times. COUNT = 0 : infinity.
TRIG = AUTO / MANUAL : the way to trigger. AUTO : it will finish all COUNT number when
trigger. MANUAL : it will execute sequence waveform for only once. It has the same result
in COUNT=1.
BASE = TIME / CYCLE:
the unit of sequence length.
COUNT = 0 [ LIST ]

= AUTO
BASE = TIME
