Subject: [time-nuts] 10544 TCXO used in H/P 5245L counter
I`m looking for a pdf of the schematic of the motherboard that the
10544 frequency reference plugs onto in the H/P 5245L counter. This
is the one that has a 723N, and a 7490N to produce a 100KHz
reference. Something is amiss with this board.
Thankyou.........................................Don.
Don,
The 10544 oscillator outputs 10 MHz, so the output from the 7490
would be 1MHz, not 100KHz. if that's what you're seeing, then it's
working properly.
I forgot to include a URL to the manual. It's right there on the HP/Agilent
web site at
http://cp.literature.agilent.com/litweb/pdf/05245-9044.pdf.
