1.4.7
Performing an Auto-Calibration
After setting up the R&S
EVSG1000, perform an auto-calibration to ensure the accu-
racy of the measurements. After initial setup, it is recommended that you perform an
auto-calibration every 2 months or if the difference of the environment temperature
changes by more than 10
°C.
If valid data for automatic calibration is not available, the message "UNCAL" is dis-
played in the status line of the R&S
EVSG1000 display.
To perform an auto-calibration
Before performing an auto-calibration, make sure that the instrument has reached its
operating temperature (after about 15 minutes of operation; for details, refer to the data
sheet).
A message in the status bar ("Instrument warming up...") indicates that the operating
temperature has not yet been reached.
During the auto-calibration procedure, do not apply any input signal to the
R&S
EVSG1000.
1. Select [Setup] > "Cal".
2. Select "Start Autocal".
3. Press [Enter].
The "Setup - CAL" display shows the status for each calibration step. When com-
pleted, after a few minutes, all entries must have the status "OK".
For more information on auto-calibration, see the R&S
EVSG1000 user manual.
