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
A M P T D 0 . 1 0 0 0 V p - p
1 . 0 0 0 0 0 0 0 0 0 k H z O + 0 . 0 0 0 0 V / O P E N
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
The amplitude can be changed continuously.
①
Press the
ENTRY
key, then the
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 ( ■ Amplitude units change)”, cf.
・ When the oscillation mode is NOISE, the output amplitude becomes half the set amplitude as a
result of the Vp-p setting only. Effective values in NOISE mode are the same as the effective
values of the 15-MHz models, such as the WF1946, with the same amplitude setting.
・
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.
