Then for Cal. select HFLAT, Call Point (start at HFLAT 1-1), Measure Value, Input Value, press Save and wait for it to complete (about 3 seconds), select Cal Point for the next step. Repeat for all 60 steps. Then your done and you didn't have to connect anything up to your DG4000, except for AC power. Hi
That isn't making any sense to me. What does "Measure Value, Input Value" mean?
If you can calibrate without connecting anything but mains why can't the thing self calibrate with one button?
Measure Value : Shows the current value (although apparently it may not be fully active) and outputs its frequency and level for you to measure.
Input Value: : Allows you can enter your new measurement value (from the Measure Value step above).
I don't how this fixes the issue with frequency response, just that it brings it all back to life, by Restoring the Original Calibration. Running the Factory Restore by itself won't do it.
Don't bother to measure or change anything. Its not required or necessary.
Just follow the steps I provided to activate the current values that were somehow unactivated from the GEL patch.
If you have already changed some values, then I would exit and restore the Factory Defaults and then repeat the procedure I provided. But, of course that's your option.
I'm of course starting to wonder if perhaps the same thing should possibly be done for AV, LFLAT, but certainly nothing else. Although I'm not going to go there at this time unless we spot a potential issue.
And by the way my frequency response up to 200 MHz looks to be +/- 0.5 dB or better so far.
Note: Do the guys here with DG4000 FW 00.01.07.00.03 and the 'ppulse and npulse' issues have this patch installed, if so, could they be getting another artifact that could be related? I don't know, but they may want to consider the possibility.
