Hi, I am using an Agilent 8163B mainframe (with 81940A laser module in slot 1 and 81980A laser module in slot 2) to measure BFB fiber laser with a photodiode. The system is controlled by LabView over GPIB. The GPIB commands sweeps laser 2 from 1520 nm to 1570 nm at 5 nm/sec. Output trigger is latched by the start sweep command which starts acquisition. Everything works fine except that at random intervals the 8163b binds up with a blue screen of death with the following message: System Panic 1 (Software assertion failed) Module 1 Assertion Failed m_Client == NULL Task: Interrupt System halted Build Information: AT, view KRFV05 Sept 24 2007 12:09:03 V5.01
After complete reboot system is fine. Any suggestions as to what causes the problem?
Hi, This may be an issue something that was seen a couple times and fixed with a newer firmware version. We're checking for that version since it isn't shown on the usual web page yet. Is the firmware on your laser modules 4.84 or older?
One other suggestion in the meantime: if you're not yet using it, the command [:SOURcen][:CHANnelm]:WAVelength:SWEep:FLAG? could be used to be sure the laser is ready to start the next sweep.
