Amplitude setting (
ENTRY
→
AMPTD
)
Amplitude (AMPTD) setting is described.
Operation:
The amplitude can be set by two methods.
(1) Keypad
Convenient when the amplitude has been determined beforehand.
For example, set 2 Vp-p as follows.
①
Press the
ENTRY
key, then the
AMPTD
key.
The following display is produced.
Amplitude
ＡＭＰＴＤ ０．１０００ Ｖｐーｐ
１．０００００００００ｋＨｚ Ｏ＋０．００００Ｖ ／ＯＰＥＮ
Frequency DC offset
② Press the
2
key, then the
ENTER
key.
To correct an entry, press the
BS
key before pressing
ENTER
key.
③
This completes setting, afterwards, press the
EXIT
key.
(2) Modify dial

AMPTD
key.
②
Select the digit to be changed with the and keys.
③ Turn the
MODIFY
dial to set the flashing digit.
④ After setting, press the
EXIT
key to release the setting mode.
Other:
・
When the oscillation mode is DC, the amplitude cannot be set.
・
Units other than Vp-p can also be set. “5.2 Units”, cf.
・
Can also be set by waveform high level and low level.
“5.1 Convenient Settings ( ■ Amplitude and DC offset setting by high and low level)”, cf.
