DC offset determines the offset component added to the waveform or the output voltage when the
oscillation mode is DC.
Setting the DC offset (OFFSET)is described.
Operation:
Two methods can be used for setting the DC offset.
(1) Keypad
Convenient when the DC offset has been determined beforehand.
For example, set +1 V as follows.
①
Press the
ENTRY
key, then the
OFFSET
key.
The following display is produced.
DC offset
ＯＦＳ ＋０．００００ Ｖ

Frequency Amplitude
② Press the
1
key, then the
ENTER
key.
