pll error in rf signal generator
sperelat - 2007-09-12 07:39:00
What I;m doing now is doing test of a rf signal generator.
My professor might buy it via e-bay.
When I turned it on, it showed Uncal warning and generated no rf
signal.
Meaning of error code was that PLL is unlocked.
I'm ,however, newcomer to RF generator world.

I am trying to do a simple experiment involving an ocilliscope and a

function generator set to produce a 10V (no load) sine wave an vary
the freq from 100-2700 Hz.

I am getting a different Vpp measurement on the scope from the signal

Techmann - 2008-12-04 02:06:00
I have a D.C. motor that spins just fine when I apply 12V to it. The

When I hook up a DC voltmeter to the leads and spin the shaft in the
same direction with my electric drill (around 1000 RPM) the most I

CptDondo - 2007-07-17 18:20:00
I've got a PLC (a little controller) that runs off a generator. The PLC

The PLC only draws a tiny amount of power - less than an amp at 120vac.
Is there an inexpensive filter we can get or build for this thing?
