Anritsu MS4630B 10Hz-300MHz network analyser teardown/repair/review
<< < (4/7) > >>
nctnico:
What kind of circuit did you try to analyse? Perhaps the signals got too small to resolve. I used to have an higher end HP LCR meter (big boat anchor) but measuring resistors in the milli-Ohm range just wasn't possible with it.
R_G_B_:
It was just a RC low pass filter.
nctnico:
Yesterday I could no longer stand the missing power button. Unfortunately I have been unable to find a replacement so I glued some PVC sheet together and milled it into the right shape:


Making the square hole at the back was a bit iffy but I used a 1.5mm mill bit to make a hole square-ish


Much better!
R_G_B_:
I have the predecessor to this network analyzer.

I managed to sort the problem with it which is the sweep speed. If its set to a fast sweep speed and the filter has a very low frequency band it would not plot. So you have to slow down the sweep speed in order for it to plot the filter response.

PartialDischarge:
Nice equipment.
Is there anything similar from other brands? I'm looking for something that can measure phase and freq response of a DUT from nearly dc to some 10-100MHz.
