Performance Tests and Calibration 1
Calibration Overview
34450A Service Guide 3
Calibration interval
A one year interval is adequate for most applications. Accuracy
specifications are warranted only if adjustment is made at regular
calibration intervals. Accuracy specifications are not warranted beyond
the one year calibration interval. Agilent does not recommend extending
calibration intervals beyond two years for any application.
Time required for calibration
The 34450A can be automatically calibrated under computer control.
With computer control you can perform the complete calibration
procedure and performance verification tests in less than 60 minutes
once the instrument is warmed- up (see“Test Considerations” on page 5).
Refer to the 34450A Programmer’s Reference online help for more
information.
Automating calibration procedures
The adjustment procedures provided in this Service Guide demonstrate
front panel adjustment. You can automate the complete verification and
adjustment procedures outlined in this manual. You can program the
instrument configurations specified for each test over the remote
interface. You can then enter read back verification data into a test
program and compare the results to the appropriate test limit values.
The instrument calibration must be unsecured to perform a calibration.
