User’s manual
RigExpert AA-2000 ZOOM is designed for high performance and uses factory
open-
short-load (OSL) calibration. To make usage more flexible for expirienced users there
are 10 user OSL profiles, that can be applied above factory OSL.
The
standards used for calibration should be of high quality. This requirement is
especially important for high frequencies (100 MHz and upper). Three different
calibration standards should be used: an “
open
”, a “
short
” and a “
load
” (usually, a
50-Ohm resistor). A place where these standards are connected during calibration is
called a
reference plane. If the calibration is done at the far end of a transmission line,
parameters of this line will be subtracted from measurement results and the analyzer
will display “true” parameters of a load.
