3.6.6 Delay time
TH2829X trigger delay means the delay time from triggering to test-start. Delay
function can set the trigger delay time. When the list sweep test function is used,
all set delay time will be delayed at each sweep test point. The range of the trigger
delay time can be set from 0s to 60s with 1ms as the resolution. The trigger delay
function is great useful when the instrument is applied in an auto test system.
When the instrument is triggered by HANDLER interface, the trigger delay time
can ensure DUT and test terminal has a reliable contact.
Operation steps for setting the delay function
Execute the following steps to set the measurement delay time.
1) Move the cursor to the DELAY zone.
2) Use numeric keys to input delay time. After pressing a numeric key, the
following unit keys will be displayed. These soft keys can replace [ENTER] to
input delay time.
 msec
 sec
3.6.7 Output impedance
TH2829X provides four output impedances for your choice: 100 Ω, 50 Ω and 30 Ω.
When testing inductance, it is necessary to input the same output impedance so
as to make data comparison with other instruments.
Note: When an bias 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
2) Press 100Ω to select the output impedance as 100Ω. Press 30Ω to select the
output impedance as 30Ω.
3.6.8 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. Deviation 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)
