Select how signals of different lengths are combined when generating multiple signals.
Append Silence (to shorter signal) - automatically adds silence samples to shorter active signal, which can work well if beginning/end of signal already contains silence samples.
Truncate To Shortest - truncates longer active waveforms to be same length as shortest active signal.
Repeat until Longest (of waveforms) - automatically repeats shorter active waveform lengths until they exceed the longest active signal length then truncate them to longest active signal length if required.
Repeat Until LCM (Least Common Multiple of signal lengths) - automatically repeats shorter active waveform lengths until they equal the calculated LCM of all active signal lengths.
In Repeat Until LCM mode, the resulting data length and download time may be very long, depending on the signal lengths and frequency offsets.
Choices: Append Silence |Truncate To Shortest | Repeat Until Longest | Repeat Until LCM
Select mode to determine sample rate of combined signals. Auto modes automatically determine final signal sample rate based on mixed signal sample rate based on mixed signal sample rate requirements and hardware limitations.
Auto (Performance) - optimized for RF performance.
Auto (Minimize) - optimizes for waveform download speed.
Note when Auto (Minimize) is selected, the Source Hardware RF Signal may contain unfiltered signal images at frequencies offset from desired RF signal by the sample rate value. This may potentially be an acceptable performance versus speed trade-off if the DUT of Analyzer Hardware bandwidth filters (removes) these unwanted RF images. If in doubt, select Auto (Performance) mode.
Manual - manually specify the desired mixed signal sample rate.
Choices: Auto (Performance) | Auto (Minimize) | Manual
Displays final mixed signal sample rage in Hz.
Displays final mixed signal total number of sampled points.
Displays final mixed signal time length.
Select the full path of the S-Parameter correction file to be used by the source hardware.
Determines whether Tx impairment corrections are applied to the downloaded waveform data.
Disabled - does not apply corrections to the signal.
Automatic - applies the narrowest and then latest calibration file tat meets these conditions: Based on same Tx Hardware as current one, Calibration Environment is same as current Correction Environment (if specified), Center Frequency is same as current Tx Center Frequency, Source Amplitude is same as current Tx Amplitude, Bandwidth is not smaller than the current Signal Bandwidth.
Manual - enter a file name in the Correction File Name field. File name must end in .scal.
Choices: Disabled | Automatic | Manual
Enter calibration environment name to filter correction file search when Correction Selection is set to Automatic.
Select correction file to be applied when Correction Selection is set to Manual. When Correction Selection is set to Automatic, the automatically selected file will be displayed here.
The VISA address for this output device. See Hardware Resource Manager for VISA address examples.
Set the RF generator amplitude.
Set the RF generator frequency.
For waveforms that are exported from an M8190A+PSG configuration with a center frequency above 20GHz, the PSG's IQ Invert feature is normally applied to the waveform. When importing the saved waveform into the Signal Optimizer software, the signal may be inverted again if the center frequency is above 20 GHz, creating an undesired signal with poor EVM. In this case, set IQ Conjugation to InvertQ to correct the inverted waveform.
Set the RF output state following a Generate and Output.

This sets/gets the DAC Amplitude for the channel. This only applies if Coupling is DAC. Note that not all configurations and FW versions of M8190A support output coupling, levels or offsets.
This sets/gets the DAC Offset for the channel. This only applies if Coupling is DAC. Note that not all configurations and FW versions of M8190A support output coupling, levels or offsets.
Sets or queries the expected reference clock frequency, if the external reference clock source is selected.
Sets or queries the expected reference clock source (not supported with B02 hardware).
External- reference is taken from REF CLK IN.
AXI - reference is taken from AXI backplane.
Determines the relationship and orientation of I and Q. Conjugation is applied on the final output to the device.
Normal- I and Q will be output normally.
InvertQ - The Q values will be inverted.

Swap- The I and Q values will be swapped.
Enable the use of an RF upconverter connected to the PSG RF output signal, true or false. When RF upconverter is enabled, the PSG RF output is used to provide an intermediate frequency (IF) signal input to the RF upconverter device. The IF input signal to the upconverter is then mixed with the user specified LO harmonic frequency to achieve the desired RF upconverter final output frequency.
Upconverter intermediate frequency (IF) input signal frequency in Hz.
Select the upconverter local oscillator (LO) type to be used.
User Controlled - you must manually configure the LO Frequency and Amplitude values.
Signal Generator (Arbitrary) - you can specify any arbitrary LO Frequency value in Hz within the signal generator's supported range. You must specify a valid Instrument Address to allow the LO Frequency and Amplitude values to be automatically controlled under software remote control.
Signal Generator (Use Harmonic) - you can specify the LO Harmonic number selection to be used for automatic calculation of the required LO Frequency (Hz) based on the currently specified IF Frequency and RF Frequency values. If the resulting automatically calculated LO Frequency (Hz) value exceeds the signal generator's supported range, it will be clipped to the supported range limit. In this case, the upconverter RF Frequency will also be clipped to the appropriate range limit for the current LO Harmonic Selection value. You must specify a valid Instrument Address to allow the LO Frequency and Amplitude values to be automatically controlled under software remote control.
