When migrating an API program developed for license option N7602B-Exx to an API program which uses license option N7602B-Fxx, the software generates multiple ambiguous reference errors.
Cause: Having two "using" statements at the same time in the API program.
Solution: Because N7602B-Fxx is a super-set of N7602B-Exx, any program written for N7602B-Exx will work with license option N7602B-Fxx by changing the "name space" to the one set up for the N7602B-Fxx option. For example, the name space for a normal GSM/EDGE carrier is written as:
using Keysight.SignalStudio.N7602.API.GsmEdgeFramed;
However, to run the same program with an EGPRS2 carrier, the previous statement needs to be replaced with:
using Keysight.SignalStudio.N7602B.API.GsmEdgeFramedEGPRS2;
After downloading the waveform, the signal generator displays the following error: Baseband Generator DAC over range.
Cause: The number of frames and some baseband filter selections (such as NONE) can result in a high crest factor, causing digital to analog converter (DAC) overflow.
Solution: Reduce the runtime scaling value. For example, 50 percent or less.
After downloading the waveform, the signal generator's front panel keys do not work.
Cause: Downloading the waveform places the signal generator in remote operation, which deactivates front panel operation.
Solution: On the signal generator, press the key to restore front panel operation.
After clicking on the tool bar, or in the System Configuration Wizard, an Authorization dialog box or license error message appears.
Cause: A license file for a signal generator being used cannot be found in the PC or in the instrument.
Solution: To be fully functional, the software requires a valid license. You must have either a permanent license or a valid 14-day trial license for each signal generator being used. To obtain a free, 14-day trial license or purchase a permanent license, see Licensing.
After clicking in the System Configuration Wizard, "FW version is not valid" appears.
Cause: The signal generator firmware needs to be upgraded.
Solution: See system requirements for information about updating the firmware.
After clicking in the System Configuration Wizard, "Connection failed" appears.
Cause: The LAN or GPIB instrument connection may not be properly enabled.
Solution: Verify that all equipment is properly connected and that the LAN or GPIB interface is correctly installed and configured. (See Keysight IO Libraries.) Ensure that the GPIB or LAN information that you entered in the System Configuration Wizard matches the instrument and interface you are using.
Creating or generating a waveform with a large number of frames or carriers may result in slow software performance.
Cause: PC memory may be insufficient for processing waveforms with large numbers of frames or carriers.
Solution: Reduce the number or frames or carriers in your waveform.
When you play a sequence of waveforms, the output power level may be incorrect while switching from one waveform to the next.
Solution: Turn ALC off.
Some dialog box selections and buttons names are truncated and/or may have the bottom of the text cut off.
Cause: When software is developed in Windows 7 with a display resolution setting that differs from yours, it may cause some viewing differences such as with selections and button names.
Solution: While there is no definitive solution, changing the display resolution to the Windows default value may alleviate the issue.
