6.4 The Setup of Offset
n Press [ OFFSET ] button.
o Key in the desired value of offset.
p Select a proper unit-button to specify the value.
Example: To set offset at 1.2Vpp, press [ OFFSET ] first, then key in [ 1 ], [ . ], [ 2 ], and press
[ Vpp ].
The limitations of input : (1) Amplitude should be among 0.01 ~ 10Vpp.
(2) Offset should be among
±5Vpp.
(3) AMPL + 2
× OFFSET ≤ 10Vpp.
6.5 The Setup of Arbitrary-Wave Compiler
This section explains the compiling procedure of arbitrary waveform by using
buttons on the front panel. The detailed example of delivering data through
optional GPIB will be stated in the chapter of communication interface.
n Set the output function to be “ARB” as stated in section 6.1.
o Press [ FREQ ] and the display will show the reading frequency of ARB
function (range 42.9496MHz/N, where N=8, 10, 12,…2 15 ).
p Press [ SHIFT ] [ ARB ] to start arbitrary-wave compilation. There will be two
set of figures on the display, the left one indicates the number of a certain point,
and the right one represents the value of that point.
q Use [ ] or [ ] buttons in the MODIFY column to check out the value of the
previous or the next point.
r To edit value of a point, press [ SHIFT ] + [ ]; key in numbers, and select a
proper unit-button to specify new value of the point.
Note: [ SHIFT ] and [ ] buttons are used together for switching the blinking state between the
number and the value of a point. Following the order of arranged points to compile
arbitrary-wave is necessary.
Example of Compiling Arbitrary-Wave
The following example will guide you to proceed the compilation of arbitrary-wave.
Here, 8 points (values are identified as 0, 400, 800, 1200, 0, 0, 0, 0 in an order)
will be compiled. The changes of waveform will be observed via an oscilloscope.
Procedure :
n Use [ ] or [ ] buttons in FUNCTION column to select [ ARB ] waveform.
o Press [ SHIFT ] and [ ARB ].
ª The display will show “arb edit” for a while then shows “0001 2047”, which
indicates that you are in the compiling mode and the value of the first point is
2047. The number “0001” will be blinking.
