Calibration interface
The user need to calibrate before the measurement. This instrument use open
short load (OSL) calibration. Users need to follow the instruction and connect
open / short/50 Ohm load respectively to the RF port and do calibration.
Calibration interface
Figure 21.:
The calibration interface is similar to measurement interface. On the left-top of
screen including frequency information, On the left-bottom of screen including
calibration information.
The user can save current calibration data to the local or external disk, or Import
history calibration data to AC-726.
Before calibration, the user need to set the correct parameters, Mainly refer to
the frequency and measurement points. The completion calibration, the
corresponding curve will display on the screen. If calibration is valid, the status
on the left-bottom will become "cal On". If calibration is invalid or unfinished, the
status will be "cal off".
After the calibration, the user can return directly to the measurement interface
for measurement.
System support different calibration kit only if user know the exact electrical
length of open/short load. Users can input this parameters in the e parameter
menu.
