M8190A + PSG

Waveform Settings

Unequal Length Adjust

Select how signals of different lengths are combined when generating multiple signals.

Choices: Append Silence |Truncate To Shortest | Repeat Until Longest | Repeat Until LCM

Sample Rate Mode

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.

Choices: Auto (Performance) | Auto (Minimize) | Manual

Mixed Sample Rate

Displays final mixed signal sample rage in Hz.

Mixed Sample Points

Displays final mixed signal total number of sampled points.

Mixed Signal Length

Displays final mixed signal time length.

S-Parameter File Name

Select the full path of the S-Parameter correction file to be used by the source hardware.

Corrections

Correction Selection Mode

Determines whether Tx impairment corrections are applied to the downloaded waveform data.

Choices: Disabled | Automatic | Manual

Calibration Environment

Enter calibration environment name to filter correction file search when Correction Selection is set to Automatic.

Correction File Name

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.

Source Setup

PSG Settings

Instrument Address

The VISA address for this output device. See Hardware Resource Manager for VISA address examples.

Amplitude

Set the RF generator amplitude.

Frequency

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.

RF On

Set the RF output state following a Generate and Output.

M8190A Settings

Instrument Address

The VISA address for the M8190A AWG output device. See Hardware Resource Manager for VISA address examples.

Channel Settings:

Chn DAC Amplitude

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.

Chn DAC Offset

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.

Clock:

Reference Clock Frequency

Sets or queries the expected reference clock frequency, if the external reference clock source is selected.

Reference Clock Source

Sets or queries the expected reference clock source (not supported with B02 hardware).

IQ Adjustment Settings

IQ Conjugation

Determines the relationship and orientation of I and Q. Conjugation is applied on the final output to the device.

Upconverter Settings

Enable Upconverter

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.

IF Frequency

Upconverter intermediate frequency (IF) input signal frequency in Hz.

LO Type

Select the upconverter local oscillator (LO) type to be used.

Choices: User Controlled | Signal Generator (Arbitrary) | Signal Generator (Use Harmonic)

RF Frequency

Upconverter RF output signal frequency in Hz.

RF Frequency Inversion

Is the Upconverter RF output signal frequency inverted, true or false.

RF On

Is the Upconverter RF output signal on, true or false.

Signal Mixer Settings

Signal On

Is the signal on, true or false.

Sample Rate Multiplier

The scale factor for the sample rate of the signal.

Offset Frequency

Signal offset frequency, can be positive or negative. If Use Phase Continuous Offset Frequency is off, this value will be used as the actual offset frequency. If Use Phase Continuous Offset Frequency is on, the Phase Continuous Offset Frequency calculated by the software will be used.

Phase Continuous Signal

Turn this on if this signal needs to be phase continuous. If this is on, the software will compute and use the closest phase continuous offset frequency. If this is off, the value entered in the Offset Frequency will be used.

Phase Continuous Offset Frequency

The closest phase continuous frequency to be entered offset frequency. Note that it may be equal to the entered offset frequency.

Relative Power

Relative signal power as a dB value.

Sample Rate

The sample rate in Hz.

Sample Points

The signal's total number of sample points.

Signal Length

The signal time length in seconds.

Repetition Count

Number of times this signal is repeated prior to final signal mixing process.
