TH2829X Series Operation Manual Chapter 3 Introduction to [MEAS]
3.7.3 LOAD
By using transport coefficient between the real test value and the standard
reference value at the preset frequency (FREQ 1
, FREQ 2 … FREQ 201), the
load correction of TH2829X can eliminate the test error. It is obvious that open,
short, and load correction can be performed at preset frequencies. The 201
preset frequencies can be set in the setup zones of Spot No.
and the frequency
can be set in FREQ
zone. The standard reference values can be set in the setup
zones of REF A
and REF B. The standard test function must be set in the FUNC
zone before setting standard reference value. When the cursor moves to FREQ
,
the MEAS LOAD soft key will be displayed. Press MEAS LOAD to perform the
load correction test.
Operation steps for setting load correction
According to the following steps, perform open/ short/ load correction test at
preset frequencies.
1) Move the cursor to FREQ, the following soft keys will be displayed:
ON
Press this soft key to make the open/short/load correction data be
available.
OFF
Press the soft key to make the open/short/load correction data be
unavailable.
MEAS OPEN
Press this soft key to execute open correction at the current frequency.
MEAS SHORT
Press this soft key to execute short correction at the current frequency.
MEAS LOAD
Press this soft key to execute the load correction at the current frequency.
2) Press the soft key ON, the original preset open/short/load correction
frequency is displayed on the frequency setting zone.
3) Use numeric keys to input the correction frequency. After pressing any
numeric key, the available unit keys (Hz, kHz and MHz) will be displayed on
the soft key zone and these soft keys can replace the [ENTER] key to input
correction frequency. When the [ENTER] key is used to input correction
frequency, the default unit is Hz.
4) Connect the test fixture to the test terminal.
5) Make the test fixture be open.
6) Press MEAS OPEN to perform open correction at the current set frequency.
The test result (G, B) of the open correction test will be displayed in the help
line (the bottom line).
7) Move the cursor to OPEN.
8) Press ON to perform the open correction calculation at preset frequency in
latter measurements.
