ARB_IQ_Sink

Symbol and Description

The ARB_IQ_Sink model downloads time domain IQ data from ADS to the R&S SMU-B10, R&S SMU-B11, and SMIQ-B60 Vector Signal Generator Arbitrary Waveform Generator and the R&S I/Q Modulation Generator.

The simulated IQ data are stored from ADS to the local PC disc and then automatically transferred to the ARB generator by calling the RS ADS Interface.
The files which are downloaded to the ARB are called "ARB_IQ_Sink_I.SIG" and "ARB_IQ_Sink_Q.SIG" and are stored in the "\data" directory of your simulation.

Pins and Files

Name	Description	Signal Type
Pin "I"	I input waveform data	Scalar Timed
Pin "Q"	Q input waveform data	Scalar Timed

1)	Not supported for AMIQ.
2)	If no filename is entered, no copy is generated on the local PC and the file is only downloaded to the ARB.
3)	The clock rate can be set in a range of
	400 Hz to 100 MHz	for SMU + B10/11
	1 kHz to 40 MHz	for SMIQ + B60
	10 Hz to 100 MHz	for AMIQ
4)	Only available for SMU.

Notes

1.	*RunPreSim* and *RunPostSim* determine if the communication with the instrument shall be done before and/or after the simulation of the circuit. If you do not the simulator to control the component, select 0 for both values.
2.	If *RunPreset* is selected, the command "SYST:PRES" (equivalent to pressing the PRESET key at the frontpanel) will be executed before other settings are performed on the instrument.
3.	If *RunRFSetup* is selected, the settings for *RFFrequency, RFLevel, RFRefOscSource* and *RFOn* will be executed.
4.	The data from the simulation are always stored as SIG files with the name "ARB_IQ_Sink_I.SIG" and "ARB_IQ_Sink_Q.SIG" in the "\data" directory of the current project. If you want additional copies of the file in the SIG or TIM format, you can specify *LocalFileName* and *LocalFileType* for name and type. The complete filenames will be <LocalFileName>_[I/Q].[SIG/TIM].
5.	If *ARBSampleClock* is set to 0, the Samples Clock is derived from the timing of the simulation. Otherwise, the entered value will be used. At least 1 component in the design must specify the timing.
6.	If *ARBOn* is selected, the ARB will be reseted, the file generated (name *ARBFileName*) by the simulation will be loaded and started.
7.	*Marker1On* and *Marker2On* specify the number of samples the marker will stay on (TTL High). The marker will then turn off (TTL Low) until the end of the waveform is reached. If you want to realize e.g. a Marker Puls with ON/OFF Ratio of 1/1, please set the value to ½ of the total samples number.
8.	Data are always written in the non-volatile memory of the instrument.

Required Licenses

This component requires the license "Design Environment" (ads_schematic) for placing the component and "Ptolemy Simulator" (sim_systime) for simulation.
