NF WF1946B - LOAD Function (Equalize Setting and Output Values)

5.5 Other settings
5-20 WF1946B
 LOAD function (equalize setting and output values) (
SYSTEM
: LOAD)
Operation is described for equalizing the amplitude (AMPTD) and DC offset (OFFSET) setting
values with the actual output values (FUNCTION OUT connector voltage).
The example is setting at the 100Ωload impedance.
Operation:
① Press the
SYSTEM
key, then use the and keys to produce the following display (LOAD
flashes).
ＯＰＥＮ
ＳＹＳＴＥＭ：

② Press the
ENTER
key, then turn the
MODIFY
dial to produce the following display(SET flashes).
ＳＥＴ ５０ Ω
ＳＹＳＴＥＭ：
3
ＬＯＡＤ ＣＯＰＹ1 → ２ ＣＯＰＹ２ → １

③ Press the
key, then turn the
MODIFY
dial to set the load impedance to 100 Ω.
The above setting calculates the actual voltage of FUNCTION OUT connector from the WF1946B
output impedance (50 Ω) and the load impedance for automatically changing the indicated value.
Other:
• The load impedance setting range is 45 to 999Ω, resolution is 1Ω.
• The WF1946B output impedance and voltage errors are not converted.
