Thanks to everyone I am learning more and more about my Z3801A/58503.
Thanks to Nigel the mystery of how a DC-DC converter with an input
marked as 48 volts can function with an input of 24 volts. I just
didnt realize that the device was designed to function with that wide
of a input tolerance. I
I just installed this update, and find that the /g/ command ([turn
off] RMS info) does not seem to work. If it is passed by the
shortcut at launch time, only the Help for Command Line Options
launches (not LH itself). If I try to invoke it from within LH, I
get an Unknown command line
I've used the Lady Heather program for only two months and I'm still
discovering the nuances of this incredible software.
One thing that seems useful would be to have the \ command write a GIF
screen image to disk with the date embedded in the name of the saved
file. With that option, the
I obtained a Z3805A from one of our popular far eastern sellers on ePay and
just got around to hooking it up to power and antenna. It appears to be
working correctly, comes on frequency, 'locks', and matches my other
standards well, at least in frequency.
However, it is not a sine wave. It is
Did you measure this while terminated into a 50 ohm load? (or whatever the
characteristic impedance is)

Sorry. I forgot that important piece of information.
It was measured on a Tek 485 set to 50 ohm input impedance. My other
standards are 50 ohm output impedance and I presume that the Z3805A is as
well but I do not know.

Hi William:
In the TV series called CSI: there are five episodes that feature a
woman called Lady Heather who's into disciplining.

Hi Brian:
A friend has an Android cell phone with built in GPS. It has a
resolution of 0.0001 arc seconds as does the GPS I just got for my camera:

I think it's a common feature of the newest SiRF chip set. What's not
know is how accurate they are.
When you start getting to less than a meter.. For absolute, you need to start
worrying about stuff like solid earth tides, plate movement, a whole host of
things are all contributors in that 10-100 cm range.
For relative work( most surveying) the effects are small over a distance of
tens of

Absolute and relative... can be a word game. It depends
GPS surveying relative to astronomical reference? I don't think so.

Sure..
That's what all those geodesy folks do. Over sufficient time span, one can
relate gps measurements to an eci frame

Their measurements are usually referenced to a known survey point via
differential methods.
