Notes/Equations

1. The CM_ESG_E443xB_Sink model collects data from a simulation and downloads the data to an ESG-D/DP Series Signal Generator. This model uses the connection manager architecture to communicate with the instrument. For more information, refer to Client-Server Architecture under the section on Operational and Functional Concepts in the Connection Manager documentation .
2. Prerequisites for using CM_ESG_E443xB_Sink are:
   • ESG-D/DP Series Signal Generator: E4430B, E4431B, E4432B, or E4433B; for information, visit the website http://www.agilent.com/find/esg.
   • ESG, Dual Arbitrary Waveform Generator module option UND.
   • Supported method of connecting the instrument to your computer through the Connection Manager architecture. For detailed setup information, refer to the Connection Manager documentation.
3. The Instrument parameter specifies a triplet that identifies the specific instrument to be used in the simulation, along with the Connection Manager server information to be used to connect to the instrument.
   To interactively select an instrument, refer to Instrument Selection under the section About Instruments Components.
   For more information regarding instrument selection, refer to Discovering Connected Hardware under the section on Getting Started with Connection Manager in the Connection Manager documentation.
4. The Start and Stop parameters specify when to start and stop data collection. The number of samples collected, Stop − Start + 1, must be in the range 16 samples to 8 Msamples, where 1 Msample = 1,048,576 samples. The ESG requires an even number of samples; the last sample is discarded if Stop − Start + 1 is odd.
5. The ARBRef parameter specifies an internal or external reference for the ESG clock generator. If set to External, the ARBRefFreq parameter sets the frequency of this clock.
6. The SampleClk parameter sets the sample clock rate for the DAC output.
7. The FileName parameter sets the name of the waveform inside the ESG that holds the downloaded data. If FileName is blank, this model does not attempt any communication with the instrument.
8. The I/Q data values passed to the sink is offset and scaled to fit the instrument waveform data format. To scale the data before downloading to the ESG, set the ScalingFactor parameter. For full waveform signal range, set ScalingFactor = 1.0.
9. If the ArbOn parameter = YES, the ESG starts generating the signal immediately after simulation data is downloaded. If ArbOn = NO (default), waveform generation must be turned on at the ESG front panel.
10. If the RFPowOn parameter = YES, the ESG turns on RF power immediately after simulation data is downloaded. If RFPowOn = NO (default), RF power must be turned on at the ESG front panel.
11. The EventMarkers parameter specifies which ESG Event markers are enabled: Event1, Event2, Both, or Neither. Event markers are used for synchronizing other instruments to the ESG. When one or both EventMarkers are enabled, Event1 and/or Event2 is set to the first sample of the downloaded Arb waveform. This is equivalent to setting the events on the front panel of the ESG.
    For more information, refer to the Agilent ESG-D/DP Series Options UND and UN5 Signal Generators manual, Chapter 2.
12. The RecFilter parameter specifies the cutoff frequency for the reconstruction filter that lies between the DAC output and the Dual Arbitrary Waveform Generator output inside the ESG.
