AWG7000 Series Service Manual
Individual Calibrations To perform individual calibrations, click the calibration buttons, starting with
10MHz Reference... , and the corresponding calibrations are executed.
Execute All Calibrations To perform all calibrations in one step, click Execute All Calibrations and all
calibrations are executed in order starting from the top. However, since data timing
calibrations are quite time consuming, it is acceptable to perform only Step 4
(Magic Cal. -2), which depends on the instrument power supply, and skip the other
steps. Instead of performing all the steps in the data timing calibration, restore and
use the calibration constants obtained by the ATS (Auto Test System) at the factory
or during servicing. The following procedures assume that this method will be
used.
Saving the Calibration
Results to EEPROM
When the calibration has been performed and the results are saved to the EEPROM
(regardless of the item, all results are saved to the EEPROM on the MIO board),
the flag under
Is Calibrated will be set to TRUE. If the calibration was successful,
the Status field will display PASS. If the calibration failed, FAIL will be displayed.
There are two types of calibration: Self calibration and Manual calibration.
„
Self calibration – The instrument performs the calibration item and ends
automatically.
„
Manual calibration – This calibration item requires external devices listed on
Table 3-1 and manual data input.
A warning message is displayed if you click a calibration button without waiting
for 20 minutes after the instrument powered on. Click the Cancel button and allow
at least 20 minutes for the instrument to warm up.
