Step 12. Calibrate the Modules
A module calibration establishes calibration factors that compensate for
imperfections in the measurement system such as variations due to ambient
temperature. Calibration is easy and quick to perform and will result in the best
instrument precision. The module calibration is recommended whenever:
• Instrument power has been cycled.
• A module has been removed and then reinserted.
• A change in the temperature of the mainframe exceeds 5°C compared to the
temperature of the last vertical (amplitude) calibration (

T > 5°C).
• The time since the last calibration has exceeded 10 hours.
To perform a module calibration
1
Turn on the N1000A.

Remove all external devices and signals from the module. The module
calibration uses known signal levels in the instrument. Introducing an outside
NOTE
Allow the instrument, with modules installed, to warm up for a period of at least one hour
before performing a vertical calibration. This ensures that the module reaches its equilibrium
temperature.
