You really need to decide what frequency range
you want.
If looking at HP, you might want to consider
'impedance analysers' too.? HP seems in have this
convention that impedance analysers can sweep a frequency
range,? whereas LCR meters work at discrete frequencies.?
My 4284A precision LCR meter measures at more
than 8000 discreet frequencies from 20 Hz to 1 MHz. But
the frequencies were either chosen by a disgruntled
employee or mentality retarded intern!
Thrre is 20 Hz, and another around 20.01 Hz,
but nothing between 750 kHz and 1 MHz. At low frequencies
the steps are ridiculously close together,? whereas at
high frequencies they are really widely spaced.?
One of the problems with HP LCR meters is the
fixtures cost a fortune.? I decided to buy a new 16047A
axial/radial fixture from Keysight, as the cost was lower
than incomplete used ones on eBay!
There's someone in Hungary selling a low cost
($50 or so) LCR meter that uses an autobalancing bridge
and 4-wire Kelvin connections. This is very similar to the
HP/Agilent/Keysight meters. Unlike other low cost meters,
it doesn't have a switch to select L, C or R, but measures
the true impedance.? I will find a link to the website if
you want it. If it was not for the fact that I have the
4284A, I would buy one.
