TH2829X Series Operation Manual Chapter 3 Introduction to [MEAS]
No matter what the current frequency is, TH2829C(CX) 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
TH2829AX is 200kHz (41 points), the highest test frequency of TH2829A is
300kHz (43 points), the highest test frequency of TH2829B(BX) is 500kHz
(45 points).
The correction point (total 201 points) can be set in Spot No. on
<CORRECTION>. Move the cursor to FREQ
to set the the short correction
frequencies 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 201 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, TH2829C will test the short spurious
impedances (resistance and reactance) of 48 frequencies. Short full
frequency correction takes about 75 seconds and in this process, the
following soft keys will be displayed.
ABORT
This soft key can be used to cancel the current short correction operation and
reserve the formal open correction data.
4) Press DCR SHORT, TH2829X will test the short resistance under DC
resistance function.
5) Press ON to validate the short correction function. TH2829X will make short
correction calculation in latter test. If FREQ 1 ~ FREQ 201 are set as OFF, the
short correction function will calculate the short correction data of the current
frequency. If FREQ 1 ~ FREQ 201 are set as ON and the current frequency is
FREQ 1, FREQ 2 or FREQ 201, the short correction data of FREQ 1, FREQ 2 or
FREQ 201 will be used in the calculation of the short correction.
6) Press OFF to turn off the short correction function. In latter test, no short
correction calculation will be performed.
