3.6.2 SHORT
The short correction function of TH2827 can eliminate the error caused by
spurious inductance (R, X) in serial with DUT as shown in figure 3-2.
Figure 3-2 Spurious Inductance
TH2827 adopts two kinds of short correction data.
No matter what the current frequency is, TH2827 will execute short
correction test on the 48 fixed frequency points. Except the 48 frequencies,
the instrument will adopt imbedding algorithm to calculate the short
correction data of different test frequencies which correspond to different
ranges. Move the cursor to the SHORT zone, and then use the MEAS SHORT
soft key to execute full frequency short correction. The 48 fixed frequencies
are the same as that in open correction. The highest test frequency of
TH2827A is 300kHz (43 points), the highest test frequency of TH2827B is
500kHz (45 points, the highest test frequency of TH2827C is 1MHz (48
points).
The calibration point can be set in SPOT No.
on <CORRECTION> and then
the short correction frequencies can be set in FREQ. Move the cursor to
FREQ
and then use the MEAS SHORT soft key to execute short correction on
selected frequency.
Operation steps of short correction function
Short correction includes full frequency short correction which adopts imbedding
algorithm and single frequency short correction on selected frequencies. Execute
the following operation steps to make short correction. The single frequency short
correction can refer to “Load correction”.
1) Move the cursor to the SHORT
zone, the following soft keys will be displayed:
ON
OFF
MEAS SHORT
DCR SHORT
2) Connect the test fixture to the test ports. Short the test fixture by using short
plate.
3) Press the MEAS SHORT soft key, TH2827 will test the short spurious
impedances (resistance and reactance) of 48 frequencies. Short full
