30
Note: When an optional bias board is selected, only 100Ω is available.
Operation steps for setting output resistance
:
Execute the following operations to set output impedance
1) Move the cursor to the Rsou zone, the following soft keys will be displayed.
100 Ω
50 Ω
30 Ω
10Ω
2) Press 100Ω to select the output impedance as 100Ω. Press 30Ω to select the output impedance as
30Ω.
3.5.8 Deviation test function
The deviation test function can make the deviation value (instead of real test value) be directly displayed
on the screen. The deviation value is equivalent to the real test value subtracting the pre-set reference
value. This function brings great convenience to observe variations of component parameters with
temperature, frequency, bias. Bias test function can be used for primary or secondary parameter or
primary and secondary parameters meanwhile. The instrument provides two deviation test modes as
below:
ΔABS (Absolute Deviation mode)
The deviation currently displayed is the difference between the test value of the DUT
and the preset
reference value. The formula of calculating ΔABS is as below:
ΔABS=X-Y
Where, X is the test value of DUT
Y is the preset reference value.
Δ% (Percentage deviation mode)
The deviation currently displayed is the percentage of the difference between the test
value of DUT and the preset reference value divided by the reference value. Its
calculating formula is as below:
Δ%=(X-Y)/Y*100[%]
Where, X is the test value of DUT.
Y is the preset reference value.
Operation steps for setting deviation test function
:
1) Move the cursor to the REF A zone to input the reference value of the primary parameter, the
following soft key will be displayed.
MEAS
When the reference component is connected with the test terminal, you should press MEAS.
Then SM6026 will test the reference component and the test result will be automatically input
as the value of REF A.
2) Use MEAS or numeric keys to input the reference value of primary parameter.
3) Move the cursor to the REF B to input the reference value of the secondary parameter, the
following soft key will be displayed.
