Adjustment Procedures
Calibration Procedure
Before starting the calibration procedure, you need to restore the calibration
constants that were obtained by ATS (Automatic Test System) at the factory or
the service center.
Restoring the Calibration
Constants
Click the Copy Calibration Data from AWG12G to MIO button in the middle
right of the Service UI window.
The calibration data saved to the EEPROM on the AWG12G board during the ATS
calibration is restored to the EEPROM on the MIO board. The calibration data on
the MIO board EEPROM is used during the following calibration procedure.
10 MHz Reference
Calibration
This procedure adjusts the built-in TCXO oscillator frequency for the 10 MHz
Reference Output.
Equipment required Prerequisites
One frequency counter
One 50
Ω BNC cable
20 minute warm-up at 20 °C to 30 °C
1. Install the test hookup and preset the instrument controls:
a. Connect a BNC cable from the 10 MHz Reference Output on the rear
panel of the arbitrary waveform generator to the CHANNEL 1 of the
frequency counter. (See Figure 3-2.)

2. Set the frequency counter CHANNEL 1 Impedance to 50 Ω .
