4.3.2 Amplitude, offset, and delay setting
① When you want to set front panel DATA/DATA output
and CLOCK 1/CLOCK 1 output, switch to 1/1 SPEED.
When you want to set rear panel 1/4 SPEED OUTPUT
(OPTION), switch to 1/4 SPEED.
② Switches whether the DATA output or DATA output is
set. When DATA/DATA TRACKING is turned on, the
DATA output amplitude and offset become the same as
the DATA output set value.
③ Set Amplitude to the desired value by turning the rotary
encoder.
④ Set the offset standard value.
V
OH
: Output ‘High Level’ is made the standard.
V
TH
: The output level center value is made the standard.
V
OL
: Output “Low Level” is made the standard.
⑤ Set the offset value. This value shows the value of the ref-
erence specified in ④.
The waveform is as follows when the amplitude is 1 Vp-p
and the offset is 1 V
OL
.
If the offset is changed to 1 V
TH
in the above condition:
Set CLOCK in the same way. The offset reference is
shared by DATA and CLOCK.
