Agilent 89600

Keysight89600 series Vector Signal Analysis (VSA) software lets you characterize complex modulated and other time-varying signals with detailed spectrum, modulation and time waveform analysis. Use these tools in RF/wireless communications applications to evaluate simulation results to see and track down design problems before they become hardware problems. This integration enables you to make the same measurements on your simulated data as you would with your Keysight equipment.

Gain the power of the 89600 VSA measurements and displays for Simulink-based designs using the 89600 Simulink link option (Keysight option 106). This option provides a VSA blockset that works with Simulink.

Use the VSA Sink block to accept data from the simulation for analysis and evaluation using the features and functionality in the 89600 VSA software. Use the VSA Source block to acquire real world signals using Keysight test equipment, and feed it into the Simulink design. You can record and playback simulated signal output for analysis at a later time.

I think what you're looking for are the AgtVsaVector properties and methods. The first thing you have to do is install the Agilent 89601 VSA software on your local pc and on the spectrum analyzer. I used version 7.20. As noted earlier, 6.x didn't play well. When you install the 89601 software on your pc, DO NOT install the Agilent IO libraries. Doing so will trash your GPIB setup because Agilent an NI used the same filename for one of the .dll's. The control I used to get to the application is just an Automation Refnum control. On the front panel: Modern/Ref Num/Automation Refnum, then rightclick on it and choose "Select Activex Class... Browse... Select "Agilent 89600 Vector Signal Analyzer Version 7.20...." in the drop down box, then select "_Application" in the table. Connect this to an Automation Open vi. You can leave the machine name unwired. Dcom will pick up the computer name to connect to through Component Services.

In the folder where the VSA software installed on your pc, there is a subfolder named "dcom". On my pc, the path is "C:\Program Files\Agilent\89600 VSA\dcom". In that folder, there is a Readme.txt file. Follow the instructions in there to set up dcom communications. The analyzer name is the computer name of the spectrum analyzer. If its an MXA, then its probably A-N9020A-(last 5 digits of serial number). You can also find this under "Show", "System" on the spectrum analyzer.

Once you've run setup.bat, you can then run testconnect.bat anytime to test the connection. All setup.bat does is set default settings in Component Services. You can do this manually through Component Services. Once that's done, it tries to launch the VSA software. Play around with the permissions until testconnect.bat is able to launch the vsa software. I gave the users I created on the vsa Full Access and things worked fine.

On the leading edge of wireless design, signal interactions can cause the unexpected. Knowing theres a problem is relatively easy. Achieving the clarity to find the root cause is the real challenge.

With views of virtually every facet of a problem, our 89600 VSA software tools let you see the why? behind signal interactions. Whether youre working with emerging or established standards, Agilents industry-leading 89600 VSA software helps you see through the complexity.

The 89600 VSA software is a comprehensive set of tools for demodulation and vector signal analysis. These tools enable you to explore virtually every facet of a signal and optimize your most advanced designs. As you assess the tradeoffs, the 89600 VSA helps you see through the complexity.

Santa Clara, CA -- Agilent Technologies Inc. announced an LTE test solution that combines the market-leading Agilent 89600 VSA LTE FDD and LTE TDD analysis software with the highest-performance member of the Agilent X-Series, the Agilent N9030A PXA signal analyzer.

The PXA provides industry-leading RF performance that supports both LTE FDD and LTE TDD. It delivers up to 140 MHz analysis bandwidth and up to 75 dB of spurious-free dynamic range with typical flatness of 0.4 dB, making it an ideal solution for 3G, 4G and beyond. LTE Advanced, one of the standards candidates for true 4G mobile broadband systems, will extend LTE to even wider bandwidth, up to 100 MHz, making the PXA an ideal investment for customers transitioning from 3G to 4G.

The PXA's bandwidth allows multi-carrier signal analysis as well as analysis and troubleshooting of the digital-predistortion (DPD) techniques applied to power amplifiers used in advanced wireless technologies such as LTE. Using the PXA's unique simultaneous 140 MHz-wide bandwidth, with up to 75 dB of spurious-free dynamic range, users can capture higher-order intermodulation products, up to seventh order for 20 MHz LTE systems, for characterization of power amplifiers using DPD techniques. Powerful, real-time corrections offer accurate, low-distortion measurements that allow vector measurements with very low residual Error Vector Magnitude (EVM).

The combination of the Agilent PXA and the Agilent 89600 VSA LTE FDD and LTE TDD analysis software enables the user to analyze all of the LTE bandwidths and all of the uplink and downlink channels and signals. It also enables the ability to make channel-selective measurements to troubleshoot by resource block, sub-carrier, slot or symbol. The VSA software has a well-designed user interface, including up to six simultaneous, user-selected displays, color coding and marker coupling among multiple traces. Using the software, users can make RF transmitter measurements on a base station as well as on user equipment using a single option.

In addition to its excellent LTE performance, the PXA's industry-leading specifications include -128 dBc/Hz phase noise at 10 kHz offset (1 GHz), 0.19 dB absolute amplitude accuracy, and -172 dBm displayed average noise level (DANL) at 2 GHz (with preamplifier and Noise Floor Extension technology). The Noise Floor Extension technology reduces the effective noise level of the signal analyzer, improving its dynamic range. This allows the PXA to achieve excellent ACLR dynamic range for complex LTE signals. The unmatched accuracy and performance reveals any issues in design, delivering confidence to the user.
