Use the niRFSG Property Node to get (read) or set (write) NI-RFSG properties. When you read a property, NI-RFSG analyzes the current configuration to return the coerced value for that property. NI-RFSG verifies many properties upon reading, thereby either transitioning the session to the verified state or alerting you of an invalid configuration. Setting a property transitions the session to an unverified state.

Property Description
Active Channel

Specifies the channel name used to access all subsequent channel-based properties in this property node. Set the channel before setting channel-based properties.

Supported Devices: PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5840 Details

Arb:Advanced:Compensate for Filter Group Delay

Enables or disables compensation for filter group delay on the AWG module. This property also accounts for the upconverter group delay and aligns the RF output with the Started Event, Done Event, and Marker Events.

At a low I/Q rate, the group delay can become so large that some devices may not be able to align the events with the RF output, in which case you must increase the I/Q rate or disable this property.

Supported Devices: PXIe-5672

Default Value: FALSE Details

Arb:Advanced:Digital Gain (dB)

Specifies the digital gain, in decibels. The digital gain is applied to the waveform data after filtering. Use this property to adjust the output power of the device while keeping the analog path fixed. This may cause clipping, overflows, or quantization noise if used improperly.

To set this property, the NI-RFSG device must be in the Configuration or Generation state.

Supported Devices: PXIe-5644/5645/5646, PXIe-5820/5840

Default Value: 0 dB Details

Arb:Advanced:Overflow Error Reporting

Configures error reporting for onboard signal processing (OSP) overflows. Overflows lead to clipping of the waveform.

Supported Devices: PXIe-5820/5840

Default Value: Warning Details

Arb:Arb Carrier Frequency (Hz)

Indicates the carrier frequency generated by the AWG module.

Supported Devices: PXI-5610, PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5840 Details

Arb:Arb Power (dBm)

Indicates the average output power from the PXI-5421, PXI-5441, PXIe-5442, and PXIe-5450 AWG modules. If an arbitrary waveform is being generated, this property specifies either the average power or the peak power of the signal, depending on the Power Level Type property setting.

Arb:Data Transfer:Advanced:Preferred Packet Size

Specifies the preferred size of the data field in a PCI Express read request packet.

In general, the larger the packet size, the more efficiently the device uses the bus. By default, RF signal generators use the largest packet size allowed by the system. However, due to different system implementations, some systems may perform better with smaller packet sizes.

Recommended values for this property are powers of two between 64 and 512.

Note  In some cases, the RF signal generator generates packets smaller than the preferred size you set with this property.

Supported Devices: PXI-5670/5671, PXIe-5672/5673/5673E Details

Arb:Data Transfer:Data Transfer Block Size

Arb:Digital Equalization Enabled

When this property is enabled, NI-RFSG equalizes the waveform data to correct for variations in the response of the NI-RFSG device. Enabling digital equalization improves the modulation error ratio (MER) and error vector magnitude (EVM) for signals with large bandwidths (>500 kHz), but it increases tuning times.

This property only applies when the Generation Mode property is set to Arb Waveform or Script. To set this property, the NI-RFSG device must be in the Configuration state.

On the PXI-5670/5671, equalization is performed in the software, so tuning time is increased. On the PXIe-5672, equalization is performed in the hardware so that there is no compromise in performance.

PXIe-5644/5645/5646, PXIe-5820/5840: Enable is the only supported value for this device.

Supported Devices: PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672, PXIe-5820/5840

To set this property, the NI-RFSG device must be in the Configuration state.

Supported Devices: PXIe-5644/5645/5646, PXI/PXIe-5650/5651/5652, PXIe-5653/5654/5654 with PXIe-5696 (CW support only), PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5840

Default Value: CW Details

Arb:IQ Rate (S/s)

This property specifies the I/Q rate of the arbitrary waveform. The I/Q rate is coerced to a value the hardware can achieve. Read this value back after setting it to see the actual I/Q rate. NI-RFSG internally uses an FIR filter with flat response up to (0.4 × IQ rate). Given a desired signal with the maximum frequency content f, sample the signal at an I/Q rate greater than or equal to (f/0.4).

This property only applies when the Generation Mode property is set to Arb Waveform or Script.

Default Value: FALSE Details

Arb:Memory Size

The total amount of memory on the RF signal generator in bytes.

Note  Not all onboard memory can be used for waveform storage. A portion of onboard memory stores scripts that specify how the waveforms are generated. These scripts typically require less than 1 KB of onboard memory.

Supported Devices: PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5840 Details

Arb:Phase Continuity Enabled

Specifies whether the driver maintains phase continuity in the arbitrary waveforms. When this property is set to Enable, NI-RFSG may increase the waveform size, and the Frequency Tolerance (Hz) property specifies the maximum allowable frequency error that can be introduced when keeping the signal phase-continuous. To set the Phase Continuity Enabled property, the NI-RFSG device must be in the Configuration state. This property only applies when the Generation Mode property is set to Arb Waveform or Script.

PXI-5671: When using the PXI-5671 with I/Q rates less than or equal to 8.33 MS/s, an input phase-continuous signal is always phase-continuous upon output, and this property has no effect.

PXIe-5644/5645/5646, PXIe-5672/5673/5673E, PXIe-5820/5840: Phase continuity is always enabled on these devices.

Arb:Pre-filter Gain (dB)

Specifies the AWG prefilter gain. The prefilter gain is applied to the waveform data before any other signal processing. Reduce this value to prevent overflow in the AWG interpolation filters. Other gains on the NI-RFSG device are automatically adjusted to compensate for nonunity AWG prefilter gain. The PXI-5671, PXIe-5672 must be in the Configuration state to use this property. However, the PXIe-5673/5673E can be in either the Configuration or the Generation state to use this property.

Note  On the PXI-5671, this property applies only when the I/Q rate is set to a value less than or equal to 8.33 MS/s. On the PXIe-5644/5645/5646, PXIe-5672/5673/5673E, and PXIe-5820/5840, this property is always applicable.

Supported Devices: PXIe-5644/5645/5646, PXI-5671, PXIe-5672/5673/5673E, PXIe-5820/5840

NI-RFSG returns an error if you use this property with a device that does not support OSP.

Supported Devices: PXI-5671, PXIe-5672/5673/5673E Details

Arb:Selected Script

Specifies the script in onboard memory to generate upon calling the niRFSG Initiate VI when the Generation Mode property is set to Script. The Selected Script property is ignored when the Generation Mode property is set to Arb Waveform or CW.

To set the Selected Script property, the NI-RFSG device must be in the Configuration state.

Supported Devices: PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5840 Details

Arb:Signal Bandwidth (Hz)

Specifies the bandwidth of the arbitrary signal. This value must be less than or equal to (0.8 × I/Q rate).

NI-RFSG defines signal bandwidth as twice the maximum I/Q signal deviation from 0 Hz. Usually, the baseband signal center frequency is 0 Hz. In such cases, the bandwidth is simply the I/Q signal's minimum frequency subtracted from its maximum frequency or fmax - fmin.

This property applies only when the Generation Mode property is set to Arb Waveform or Script, except for when using the PXIe-5840, which supports setting this property in all supported generation modes. To set the Signal Bandwidth property, the NI-RFSG device must be in the Configuration state.

PXI-5670/5671, PXIe-5672: Based on your signal bandwidth, NI-RFSG decides whether to configure the upconverter center frequency in increments of 1 MHz or 5 MHz. Failure to configure this property may result in the signal being placed outside the upconverter passband.

PXIe-5644/5645/5646, PXIe-5673/5673E: This property is used only for error checking purposes. Otherwise, this property is ignored.

PXIe-5820/5840: Based on your signal bandwidth, NI-RFSG decides the equalized bandwidth. If this property is not set, NI-RFSG uses the maximum available signal bandwidth. For the PXIe-5840, the maximum allowed signal bandwidth depends on the upconverter center frequency. Refer to the specifications document for your device for more information about signal bandwidth. The device specifications depend on the signal bandwidth.

Supported Devices: PXI-5610, PXIe-5611, PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5840 Details
