It looks identical to my Agilent U1732B, thjough I think the Agilent's spec
is poorer. It was replaced by a U1732C which may be closer thjough both are
going back a way now. Presumably Agilent badged it and it has continued to
improve. I don't know whether there's a corresponding Keysight version.
The Tonghui has arrived. It is ideal for measuring small RF components. It
has a resolution of 100 microohms, 1 nanohenry and 0.001 picofarad.
There is no need to buy Kelvin clips. It comes with a complete set,
including SMD and ordinary multimeter clips.
TH2822 series are equipped with the

Ed,
You spoke of difficulty measuring inductors. There are quite a few LCR
meters on the market that offer the performance needed in your project.
Here are three:

Yes. NIST

Hi Markus,
I've pasted output from some pmc GET commands below, along with show
clock on the GM. Seems like the grandmaster is getting 37 from GPS,
while announcing 35?
Also not sure why TIME_PROPERTIES_DATA_SET has currentUtcOffsetValid and
timeTraceable both set to true, but
Hi Andrew,
have you checked the PTP-Messages themselves? There is a field
currentUtcOffset in the PTP announce message used to transfer leapsecond
info. If thats 35, then it seems like a firmware issue.
Regards

Of course with a noise source you get 3dB as both sidebands fold.

Hi Hans-Georg,
Maybe it is better to refer to this as the inverse of 20,48 GHz, since
that is the virtual clock rate of the interpolated coarse-clock.
Considering that it is 2048 * 10 MHz, it is not hard to imagine that a
coarse clock of say 80 MHz is then interpolated by 256 to achieve that,
10 matches
