Adjustment Procedures
3. Click the 10MHz
Reference... button in the AwgService UI window to
display the following setup window:
Figure 3-3: 10 MHz Reference Calibration setup window
4. Change the 10 MHz Reference value using the up/down button or the
front-panel rotary knob so that the frequency counter reading is within the
range of 10 MHz ±1 Hz.
5. Click Save to EEPROM to save the data to the EEPROM.
6. Click Close to close the window.
YIG Drive Current
Calibration
This is a self calibration. The YIG for the internal clock source controls the
frequency by the main coil (tuning coil) and the FM coil currents. The sensitivity
differs between individual YIGs, this calibration is required to set the precise
frequency.
Clock Power Calibration
This is a self calibration. In the instrument, the clock power is need to be
controlled depending on the frequency so that the clock amplitude supplied from
the CLK12G board to the DAC has always the proper value. If you fail to perform
the calibration, the DAC does not work properly, and the AWG12G board may
no
t work properly.
IPC Timing Calibration
This is a self calibration. The instrument features high-speed communication
called IPC (Inter PLD Communication) between the internal Memory Controller
and the Awg Controller. This calibration ensures the optimum timing to enable
the IPC in all frequency settings. Failing to perform this calibration may disable
access to the waveform memory and/or make the AWG board diagnostics cause
an error.
