NF WF1945B - LOAD Function (Equalize Setting and Output Values)

5.5 Other settings
5-20 WF1945B
 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 100Ω load impedance.
Operation:
① Press the
SYSTEM
key, then use the and keys to produce the following display (LOAD
flashes).

② Press the

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 WF1945B
output impedance (50 Ω) and the load impedance for automatically changing the indicated value.
Other:
• The load impedance setting range is 45 to 999 Ω, resolution is 1 Ω.
• The WF1945B output impedance and voltage errors are not converted.
