NI recommends the NI PXIe-5673E instead of the NI PXIe-5673.

The NI PXIe-5673 is a wide-bandwidth 6.6 GHz RF vector signal generator (VSG). Combined with appropriate software, this module can generate a variety of signals. Using the NI LabVIEW Modulation Toolkit, the NI PXIe-5673 can generate different waveforms including AM, FM, CPM, ASK, FSK, MSK, PSK, QAM (4, 16, 64, and 256), multitone signals, and arbitrary waveforms. In addition, you can combine this VSG with standard-specific software to generate signals for GPS, GSM/EDGE/WCDMA, WLAN, WiMAX, DVB-C/H/C, ISDB-T, ZigBee, and others. One key feature of the NI PXIe-5673 is its stream-from-disk capabilities, which you can use to generate continuous waveforms that are up to several terabytes in length.
