Hi Guiseppi I think I have some papers on them somewhere.I cant remember the
model numbers. If you are refering to the units in blue crackle diecast case
with miniature toggle switches the spec max frequency is 150MHz from memory.
I did plot one some time ago on my Spectrum Analyser and TG, They are usable
to 200MHz with reduced accuracy.

Subject: [time-nuts] OT - Old Hatfield 2105 Step attenuator specs
Hello to all,
and Happy New Year.
I would like to know the specs for this attenuator, especially the maximum
frequency, if any good folk has a ballpark idea...
I was not able to locate any info about it.
Thanks in advance.
