content: Anyone have experience with TLA7E2? Try to run it on TLA721 and facing two strange issue:1. After flash the firmware, all test passed but version is 3.1.1 (Is that the FW version come with TLA 5.1 SP1).2. Run with DSO seems be fine until I click the Stop. It report exception and crashed the TLA App. (Need help with the highlighted error part in Red) Call trace as below:11/23/2021 8:05 PM 16.0204 0.0016s viRead(0x8029608, "TEKTRONIX,TLA7E2,B010286,SCPI:95.0 FVER:3.1.1\n", 1024, 0x12f0a4(46))11/23/2021 8:05 PM 16.0304 0.0004s viWrite(0x8029608, ":inp1:prob:id?", 14, 0x12f024(14))11/23/2021 8:05 PM 16.0404 0.0023s viRead(0x8029608, """\n", 1024, 0x12eff4(3))11/23/2021 8:05 PM 16.0504 0.0003s viWrite(0x8029608, ":inp2:prob:id?", 14, 0x12f024(14))11/23/2021 8:05 PM 16.0604 0.0007s viRead(0x8029608, """\n", 1024, 0x12eff4(3))11/23/2021 8:05 PM 16.0704 0.0003s viWrite(0x8029608, ":inp3:prob:id?", 14, 0x12f024(14))11/23/2021 8:05 PM 16.0804 0.0014s viRead(0x8029608, """\n", 1024, 0x12eff4(3))11/23/2021 8:05 PM 16.0905 0.0003s viWrite(0x8029608, ":inp4:prob:id?", 14, 0x12f024(14))11/23/2021 8:05 PM 17.0005 0.0008s viRead(0x8029608, """\n", 1024, 0x12eff4(3))11/23/2021 8:07 PM 57.0496 0.0005s viWrite(0x8011520, "SIGN:SOUR OFF;:RUN:SOUR OFF;:ARM:SOUR OFF;:TRIG:SOUR OFF;:TRIG:OUT:DEST OFF;:SIGN:OUT:DEST OFF", 94, 0x12ed0c(94))11/23/2021 8:07 PM 57.0556 0.0005s viWrite(0x801de30, "SIGN:SOUR OFF;:RUN:SOUR OFF;:ARM:SOUR OFF;:TRIG:SOUR OFF;:TRIG:OUT:DEST OFF;:SIGN:OUT:DEST OFF", 94, 0x12ed0c(94))11/23/2021 8:07 PM 57.0606 0.0005s viWrite(0x8029608, ":outp:eclt0 0;eclt1 0;ttlt0 0;ttlt1 0;ttlt2 0;ttlt3 0;ttlt4 0;ttlt5 0;ttlt6 0;ttlt7 0;", 86, 0x12ed34(86))11/23/2021 8:07 PM 57.0746 0.0757s viWrite(0x8029608, ":volt1:rang:ptp 5.000e+000;offs 1.500e+000;:inp1:imp max;coup dc;filt 0;:volt2:rang:ptp 5.000e+000;o", 467, 0x12ed18(467))11/23/2021 8:07 PM 59.0038 1.2427s viWrite(0x8029608, ":OUTP:ECLT0:POL NORM;:OUTP:ECLT1:POL NORM;:OUTP:TTLT0:POL NORM;:OUTP:TTLT1:POL NORM;", 84, 0x12ed14(84))11/23/2021 8:07 PM 59.0228 0.1360s viWrite(0x8029608, ":trace:list none;:init", 22, 0x12ed04(22))11/23/2021 8:07 PM 59.0799 0.0002s viGetAttribute(0x8029608, VI_ATTR_RSRC_NAME, 0xb4cfc68("VXI0::4::INSTR"))11/23/2021 8:07 PM 59.0859 0.0002s viGetAttribute(0xc9792a0, VI_ATTR_SIGP_STATUS_ID, 0xb4cfc64(39684))11/23/2021 8:07 PM 59.0919 0.0002s viClose(0xc9792a0)11/23/2021 8:07 PM 59.0979 0.0002s viGetAttribute(0x8029608, VI_ATTR_RSRC_NAME, 0xb4cfc68("VXI0::4::INSTR"))11/23/2021 8:08 PM 0.0039 0.0002s viGetAttribute(0xc9792a0, VI_ATTR_SIGP_STATUS_ID, 0xb4cfc64(39940))11/23/2021 8:08 PM 0.0099 0.0002s viClose(0xc9792a0)11/23/2021 8:08 PM 0.0149 0.0002s viGetAttribute(0x8029608, VI_ATTR_RSRC_NAME, 0xb4cfc68("VXI0::4::INSTR"))11/23/2021 8:08 PM 0.0199 0.0002s viGetAttribute(0xc9792a0, VI_ATTR_SIGP_STATUS_ID, 0xb4cfc64(40196))11/23/2021 8:08 PM 0.0270 0.0002s viClose(0xc9792a0)11/23/2021 8:08 PM 25.0316 0.0002s viGetAttribute(0x8029608, VI_ATTR_RSRC_NAME, 0xb4cfc68("VXI0::4::INSTR"))11/23/2021 8:08 PM 25.0376 0.0002s viGetAttribute(0xc9792a0, VI_ATTR_SIGP_STATUS_ID, 0xb4cfc64(40452))11/23/2021 8:08 PM 25.0446 0.0002s viClose(0xc9792a0)11/23/2021 8:08 PM 25.0516 0.0002s viGetAttribute(0x8029608, VI_ATTR_RSRC_NAME, 0xb4cfc68("VXI0::4::INSTR"))11/23/2021 8:08 PM 25.0586 0.0002s viGetAttribute(0xc9792a0, VI_ATTR_SIGP_STATUS_ID, 0xb4cfc64(40708))11/23/2021 8:08 PM 25.0656 0.0003s viWrite(0x8029608, ":outp:res;:trig:cau?", 20, 0x12f2f4(20))11/23/2021 8:08 PM 25.0666 0.0001s viClose(0xc9792a0)11/23/2021 8:08 PM 25.0746 0.0002s viGetAttribute(0x8029608, VI_ATTR_RSRC_NAME, 0xb4cfc68("VXI0::4::INSTR"))11/23/2021 8:08 PM 25.0806 0.0058s viRead(0x8029608, "0\n", 1024, 0x12f2a8(2))11/23/2021 8:08 PM 25.0866 0.0001s viGetAttribute(0xc9792a0, VI_ATTR_SIGP_STATUS_ID, 0xb4cfc64(40964))11/23/2021 8:08 PM 25.0926 0.0003s viWrite(0x8029608, ":trac:timing?", 13, 0x12f1f4(13))11/23/2021 8:08 PM 26.0007 0.0002s viClose(0xc9792a0)11/23/2021 8:08 PM 26.0057 0.0086s viRead(0x8029608, "2.52299574333193E+01,7.499516E-06\n", 1024, 0x12f1c4(34))11/23/2021 8:08 PM 26.0117 0.0004s viWrite(0x8029608, ":trac:list chan1,chan2,chan3,chan4;copy fdc1,list;", 50, 0x12f1f4(50))11/23/2021 8:08 PM 26.0267 0.0880s viRead(0x802c988, "", 120033, 0x12f1e8(0)) -

content: Again, proof of my stupid. For anyone facing same issue, consider change your TLA7E2's slot position. I have one TLA7PG2 in the middle (Between two TLA7AA3 and TLA7E2) and seems TLA doesn't like that. After move TLAPG2 to the end, everything start working. Maybe some FDC channel ordering thing?
