Definition of PITA = Calibrating the HDG2002B to 100Mhz :phew: Definition of Sucks = Realizing afterward you did the whole thing with 20Mhz BWL on :palm: |O Oh FWIW, at 100Mhz @ 1Vpp with BWL on it read 100Mhz @1.01Vpp. Now it's 3-4Vpp without BWL on :scared: :palm: :-BROKE |

I Reran the Calibration and after a total of 127 Measurements total, 12 on the DM3058E in the 200mV, 5V and 20V ranges and the rest on the MSO1104Z I made it through it all :phew: The good news it it's allot more accurate now The bad news CH1 Zoom 1 still fails More good news is I found where i can change the default key to Print Screen instead :clap: but you can't print the Hardware/Software Pages :wtf: @fremen67 If you have the firmware stuff so I can downgrade to 1.02 and give that a try I would appreciate it. But also to upgrade it back to 1.03 after. I am really hoping its a bug in the self test in 1.03. and this should prove it |

That's not fair, 127 are too easy ;) --- Quote from: smgvbest on January 24, 2015, 06:45:12 am ---@fremen67 If you have the firmware stuff so I can downgrade to 1.02 and give that a try I would appreciate it.

I will try to create an upgrade package so that you don't need to connect to the serial nor to the JTAG port. I just have to figure out the best way to enter recover mode without manually stopping the boot process. |

I did some tests yesterday with the HDG and my DS1054z using Agilent Connection Expert. With the right driver (IVI) you can control the HDG calibration process with SCPI commands. You can also easily control and read values from the DS1054z. That means that it should not be that difficult to write a script that would automate the calibration process. At least a part of it for me as I don't have a SCPI compliant DMM. One advantage of calibrating the HDG via SCPI, apart of the PITA part ;), would be that you may be able to jump directly to one of the 90 calibration steps (for SW 1.00.3). That means you could calibrate separatly the DC part and one of the 3 amplification stages. The documentation is quite lite but there are at least some information on those calibration commands: CALibration:SETup <step> CALibration? CALibration:VALue <value> CALibration:STORe There is a 1 offset in the steps between the manual calibration in front of the HDG and the calibration via SCPI. This you can also see on the video posted by Scope Sam CALibration:SETup 2 outputs the first DC calibration value and CALibration:SETup 91 outputs the last AC calibration one . |
