4.6 Output of Arbitrary Waveforms
Arbitrary waveforms are generated by transferring data from an external PC to arbitrary waveform
memory via USB interface. (It can not be available to transfer via RS232 interface.)
Arbitrary waveforms can be edited and transferred using the accompanying control software.
See the
control software user’s manual
, for description of this control software.
When output is on, arbitrary waveforms cannot be changed. Make sure that output is off before changing
arbitrary waveforms.
a) Arbitrary waveform memory
The APS-1102A includes arbitrary waveform memory as an internal signal source, and this memory
can be written to via the USB interface. Arbitrary waveform memory cannot be written to from the
panel screen.
Waveform memory count: 16
Waveform length:
4096 [words]
Waveform data:
15-bit binary (2’s complement format)
The valid range of waveform data is from
16384 to 16383.
If a value less than
16384 is input, the waveform data is clipped to
16384, and if a value greater than
16383 is input, the waveform data is clipped to 16383.
When the power source is off, arbitrary waveform memory data is retained by battery backup.
At the initial settings (factory settings) and when the memory is cleared, a sine wave is written to
ARB1 to ARB8, a square wave is written to ARB9 to ARB12, and a triangle wave is written to ARB13
to ARB16.
b) Output of arbitrary waveform
To select an arbitrary waveform, select
in the SET menu.
