M9381A PXIe vector signal generator

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.

N5182A MXG Vector Signal Generator - requires firmware version A.01.10 or later (how to upgrade)

N5182A-503

250 kHz to 3 GHz frequency range

Or the other frequency option:

     N5182A-506

250 kHz to 6 GHz frequency range

N5182A-651

Internal Baseband Generator (30 MSa/s and 8 MSa)

Or one of the Closedother internal baseband generator options:

Simple guidelines for deciding which internal baseband generator you will need is using the following equation:

Sample Size = ARB Sample Clock X Oversampling Ratio X Number of Carriers

As example,

  • If you have an ARB Sample Clock rate of 1.2288 MHz and you are testing with 4 carriers and an oversampling ratio of 4,

    Sample Size

    = 1.2288 MHz X 4 X 4

    = 19.6608 MSa/s

    Since 19.6608 MSa/s is less than the 30 MSa/s capability of option 651, this internal baseband generator should be adequate for this testing.

  • If you have an ARB Sample Clock rate of 1.2288 MHz and you are testing with 10 carriers and an oversampling ratio of 4,

    Sample Size

    = 1.2288 MHz X 4 X 10

    = 49.152 MSa/s

    Since 49.152 MSa/s is greater than the 30 MSa/s capability of option 651, this internal baseband generator will not be adequate for this testing. However, option 652 has 60 MSa/s capability. So the option 652 internal baseband generator should be adequate for this testing.
