Adjustment Procedures
Data Timing-RAM Timing
Calibration
This is a self ca
libration. The instrument outputs a waveform while reading
the waveform data from the internal RAM to the Memory Controller PLD.
This calibration ensures the optimum timing to enable waveform outputs in all
frequency settings. If you fail to perform the calibration, a waveform data may
not be read from the waveform memory correctly.
Data Timing-PLD Timing
Calibration
This is a self calibration. The instrument outputs a waveform while transferring a
waveform data from the Memory Controller PLD to the ASIC of the following
stage. This calibration ensures the optimum timing to enable waveform outputs
in all frequency settings. If you fail to perform the calibration, a waveform data
cannot be
transferred properly, and the waveform may not be output normally.
Analog Output Level
Calibration
This is a s elf calibration. This calibration ensures that the analog output levels
are within the specified range.
Marker O
utput Level
Calibration
This is a self calibration. This calibration ensures that the marker output levels
are within the specified range.
Marker Delay Calibration
This is a self calibration. This calibration ensures that the marker delay is within
the specified range.
Marker Output Cross Point
Calibration
This is a self calibration. This calibration ensures that the marker output cross
point is within the specified range.
Inter-Channel Skew
Calibration (AWG7122C,
AWG7082C, AWG7122B,
and AWG7062B)
This
calibration ensures that the Ch 1 and Ch 2 output skews are set within the
specified range. This calibration is applied to both analog and marker outputs.
