  • Version C.06.26 or later

Required options:

  • E8267D-602 (internal baseband generator with 64 Msa memory and digital bus capability)

Use power search with ALC turned off to get accurate power.

M9381A PXIe vector signal generator (single-channel configurations)

Driver:

  • Version 1.4.400.0 or later

Recommended options:

  • M9381A-M05 (memory 512 Msa)

  • M9381A-M10 (memory 1024 Msa)

  • M9381A-1EA (high output power)

  • M9381A-B10 (RF modulation bandwidth 100 MHz)

  • M9381A-B16 (RF modulation bandwidth 160 MHz)

Additional options to consider:

  • M9381A-F06 (frequency range 1 MHz to 6 GHz)

Limitations:

The M9381A VSG has a limitation related to the Power Search and DC Cal functions, creating a time-synchronization loss. That is, the signal timing changes after a Power Search or DC Cal. When ALC is set to Off, Signal Studio automatically runs Power Search, which affects the user's trigger signal for starting waveform playback. Even though the timing alignment of the trigger signal and waveform are properly set, the Power Search function disrupts this synchronization. In these cases, use the following workarounds:

  • Set ALC to On whenever possible. This avoids the automatic Power Search.

  • When ALC must be set to Off (or is set to Off by Signal Studio), you can re-trigger the signal by turning ARB Off, then On, and then send the trigger signal to M9381A VSG.

For DC Cal, run it before you download and play the waveform. Do not run DC Cal while the signal is playing, which disrupts the synchronization.

M9381A PXIe vector signal generator (multichannel synchronization)

Driver:

  • Version 2.1.000.0 or later

Required options:

  • Y1299A-001 (PXI multichannel/MIMO reference solution kit)

    • For multichannel operation, the Signal Studio software assumes the M9381A VSG follows the multichannel reference solution typical configuration, using the accompanying configuration tools. Refer to the LTE/LTE-Advanced Multi-Channel, Reference Solution Startup Guide for more information.

    • Also refer to the “Multi-Channel Reference Solution Typical Configuration” section of the M9381A PXIe Vector Signal Generator Configuration Guide.

Required for 8-channel configurations:

  • M9950A-1TP (Signal Studio software extension from 4 to 8 channels)

Recommended options:

  • M9381A-012 (LO sharing for phase coherency)

Limitations:

The M9381A VSG has a limitation related to the Power Search and DC Cal functions, creating a time-synchronization loss. That is, the signal timing changes after a Power Search or DC Cal. When ALC is set to Off, Signal Studio automatically runs Power Search, which affects the user's trigger signal for starting waveform playback. Even though the timing alignment of the trigger signal and waveform are properly set, the Power Search function disrupts this synchronization. In these cases, use the following workarounds:

  • Set ALC to On whenever possible. This avoids the automatic Power Search.

  • When ALC must be set to Off (or is set to Off by Signal Studio), you can re-trigger the signal by turning ARB Off, then On, and then send the trigger signal to M9381A VSG.

For DC Cal, run it before you download and play the waveform. Do not run DC Cal while the signal is playing, which disrupts the synchronization.
