N7609C System Requirements

The N7609C Signal Studio for Global Navigation Satellite Systems 2026 software can be installed on a PC for use with the N5172B EXG or N5182B MXG X-series signal generators. The PC software allows the user to configure settings, generates scenario data, and provides a user interface for real-time control of the signals being produced by the signal generators.

Requirements

N5172B EXG X-Series RF vector signal generator

Firmware:

  • Version B.01.75 or later

Required options:

  • N5172B-503 (9 kHz to 3 GHz frequency range)

  • N5172B-653 (internal baseband generator, 32 Msa/s, up to 60 MHz RF bandwidth)

  • N5172B-660 (upgrade baseband generator with real-time capability)

Recommended options:

  • N5172B-009 (internal Flash drive)

  • N5172B-403 (calibrated AWGN for testing with noise)

N5172B-660 is not required for “Basic Single Satellite Waveform” and “Basic Multi-satellite Waveform” capabilities.

N5182B MXG X-Series RF vector signal generator

Firmware:

  • Version B.01.75 or later

Required options:

  • N5182B-503 (9 kHz to 3 GHz frequency range)

  • N5182B-656 (internal baseband generator, 32 Msa/s, up to 80 MHz RF bandwidth)

  • N5182B-660 (upgrade baseband generator with real-time capability)

Recommended options:

  • N5182B-009 (internal Flash drive)

  • N5182B-1EQ (low power output for Rx testing)

  • N5182B-403 (calibrated AWGN for testing with noise)

  • N5182B-UNX (low phase noise)

N5182B-660 is not required for “Basic Single Satellite Waveform” and “Basic Multi-satellite Waveform” capabilities.

E8267D PSG vector signal generator

Firmware:

  • Version C.06.26 or later

Required options:

  • E8267D-520 (250 kHz to 20 GHz frequency range)

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

Recommended options:

  • E8267D-005 (6 GB internal hard drive)

  • E8267D-403 (calibrated AWGN for testing with noise)

  • E8267D-UNR (enhanced phase noise performance)

M9381A PXIe vector signal generator

Driver:

  • Version 1.4.400.0 or later

Recommended options:

  • M9381A-F03 (1 MHz to 3 GHz frequency range)

  • M9381A-B04 (RF modulation bandwidth 40 MHz)

  • M9381A-M01 (memory 32 Msa)

  • M9381A-300 (adds M9300A PXIe frequency reference, if one is not already in the system)

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.

E6640A EXM wireless test set

Software:

  • Version E.16.06 or later

Recommended options:

  • E6640A-B85 (increases signal bandwidth to 80 MHz)

  • E6640A-B1X (increases signal bandwidth to 160 MHz)

PC Requirements

200 GB HDD with 2 GB free disk space at runtime (5 GB or higher recommended)

1024 x 768 screen resolution (1280 x 1024 recommended)

If you use a high-resolution display, the GUI's font size may appear too small to read. To resolve this, lower your PC's display resolution, but make sure the display scaling remains set at 100 percent, otherwise portions of the GUI will become truncated and hidden from view.
