following monitoring zones. The monitoring zones are similar with the setting
zones, but the monitoring zones can only provide information and you cannot
change state or parameter of these zones, except REF A and REF B.
The real test results of load correction can be tested on FREQ.
3.7.1 OPEN
The open correction function of TH2829X can eliminate the error caused by the
stray admittance (G, B) parallel-connected with DUT, shown as figure 3-1.

TH2829X adopts the following two kinds of open correction data:
TH2829C(CX) will automatically make open correction test on 48 fixed
frequency points no matter what the currently set frequency is. Based on the
open correction data of the following 48 frequencies, the instrument can
calculate all open correction data of different test ranges which corresponds
to all test frequencies. Move the cursor to OPEN
and then used MEAS OPEN
to execute full frequency 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 following is taking TH2829C as the example:
20 Hz 100 Hz 1 kHz 10 kHz 100 kHz 1MHz
25 Hz 120 Hz 1.2 kHz 12 kHz 120 kHz
30 Hz 150 Hz 1.5 kHz 15 kHz 150 kHz
40 Hz 200 Hz 2 kHz 20 kHz 200 kHz
50 Hz 250 Hz 2.5 kHz 25 kHz 250 kHz
60 Hz 300 Hz 3 kHz 30 kHz 300 kHz
80 Hz 400 Hz 4 kHz 40 kHz 400 kHz
500 Hz 5 kHz 50 kHz 500 kHz
600 Hz 6 kHz 60 kHz 600 kHz
800 Hz 8 kHz 80 kHz 800 kHz
The correction point (total 201 points) can be set in Spot No. on
<CORRECTION>. Move the cursor to FREQ
to set the the open correction
frequencies and then use the MEAS OPEN
soft key to execute open
correction on selected frequency.
