The touch information from the touch screen is processed by Windows drivers, actively placing the pointer at the touched location. Actions from the mouse and the touch panel are interchangeable, and treated alike by the user interface software.

Power Supply
Fans
The CD/DVD drive is connected to the Windows via an interface connector on the μATX board. AWG7000C Series models connect using the SATA interface. AWG7000B Series models connect using the IDE parallel interface.
The power supply CVR460 is a switching AC to DC converter. It automatically detects the line voltage over the range of 90 to 264 VAC. It supplies power to all the circuitry in the instrument. No switch completely disconnects the line power from the instrument. The ON/STBY switch controls the power to the instrument through the μATX board circuitry. When in the “power off” condition, there is still a low power standby current to allow the system to monitor the ON/STBY switch.
Three fans on the side of the instrument provide forced air cooling. The fans are controlled by the fan speed control circuit on the PWR board and are regulated by monitoring the temperature at the circuitry.

The CLK12G board provides a 6 GHz to 12 GHz clock to the AWG12G board. Two clock outputs go to the CH1 and CH2 DAC. The clock output to CH2 s hould be terminated for 1 channel models. The clock input accepts 6 GHz to 12 GHz clock signals from an external signal source. The reference clock input accepts 10 MHz to 8 10 MHz reference output can be used for synchronizing frequency between two or more instruments. The CLK12G board consists of the following blocks:
YIG oscillator (6 GHz to 12 GHz)
Fractio
10.0 MHz TCXO (reference oscillator)
The AWG12G board generates arbitrary waveforms based on the waveform memory and the sequence memory. There are two types of PLDs (Xilinx FPGA) on the board. One is an AWG controller called PLD131, which interfaces to/from the M waveform patterns. Waveform data is stored in ZBT type SRAMs. The sequence memory is included in the memory controller PLD.

Adjustment Procedures
This section contains information about instrument adjustment. Only qualied personnel should perform adjustment procedures. Read the Service Safety Summary and the General Safety Summary before p erforming any service procedures.
Adjustment Interval
Adjustment After Repair
NOTE. Befor
e performing adjustment procedures, you must warm up the arbitrary waveform generator at least 20 minutes in an ambient temperature between 20 °C and 30 °C. Adjustments performed before warm-up or outside this temperature range may result in poor performance.
If the instrument fails performance tests (refer to the AWG7000 Series Arbitrary Wav e for
m Generators Technical Reference Manual), adjustment may be required.
If periodic calibration is one of your requirements, a general rule is to verify
mance and make adjustments (if needed) every 2000 hours of operation (or
perfor once a y ear if the instrument is used infrequently).
After removal and replacement of a module due to electrical failure, you must perform the adjustment procedure if the module you replaced is marked “yes” in the following table. (See Table 1.)

The primary diagnostics for the instrument are accessible through the AWG application software. The Instrument diagnostics check the basic functionality of analog and marker output at every power on. The Instrument Diagnostics run after Windows has booted up and run its own set of system checks. If any failures occur at pow provides an error code:
Diagnostics error codes (See Table 8 on page 86.)

The power-on tests ensure that the hardware is installed and can be accessed by the software. The tests provide limited diagnostic information, and provide no performance information.
To run the instrument Diagnostics manually, do these steps:
