Re: [time-nuts] Introduction of Z38XX
Gents, the first users of Z38XX have found some issues with the software. I hope I have already fixed them but I want to wait for the feedback. ASAP I will inform you wheter the new version is free of this issues.

Re: [time-nuts] Introduction of Z38XX
Gents, in the meantime I have received some feedback. Please read it with my answers in case you noticed something similar: > 1. The vertical scale has some issues. It goes down from 10-8 > to 10-23 and then goes up again to 10-7. Read the 10-23 as "near zero". Everything below should have a "-" sign, indicating negative values. I enclose a picture how it looks here. > The EFC value is remains fixed at > 65000. My Z3801 goes to EFC 696364 so stays at the top always. All scales are "autoscaling" and should follow whatever values you have. You mave have however put the autoscaling out of work by zooming into the grahics or by panning the graphics. Zooming is initiated by pressing the left mousebutton at the top left point of the area to be zoomed and then draw a white rectangle to the bottom right point of the area to be zoomed. Panning is initiated by pressing the right mouse button within the graphics and then move the mouse while the button is pressed. You can use both actions as often as you want and return to your initial screen by "reverse zoom" action, i.e. press the left mouse button anywhere in the graphics and move the mouse left and up while the button is pressed. A second possibility were that you have played around with the chart editor and switched the scale to a fixed value. In this case you can turn everything to the start values by termintaing the program and then start it again. All existing data will be read in again so will only loose one value or two > 2. The holdover unc. and sats the sat scale is not OK. It > seems to indicate twice the number of tracked sats and a high > number (76) of visible sats. First check whether the visible and tracked number of sats is shown correct in the main screen's status bar. If the error is already there then check in the parameters whether the "Where to look for data in the status screen" values are correct for you (You can count the lines in the receiver status screen). May be that I initialized these values wrong as long as no Z3801.Ini is available. 73 de Ulrich, DF6JB > -Ursprüngliche Nachricht- > Von: time-nuts-boun...@febo.com > [mailto:time-nuts-boun...@febo.com] Im Auftrag von Ulrich Bangert > Gesendet: Dienstag, 23.

Re: [time-nuts] Introduction of Z38XX
Hi Ulrich, since our FireFly and Fury GPSDO's support GPSCon as well, I tried your plot program. We use 115.200 baud by default, but when I set your program to that speed, it defaults back to 57600 for some reason. Changing our board's baud rate fixed that problem. Our status output is shown properly in your status window (see below), and the *IDN? string is shown as well, but the program says "the last smartclock status is undefined". What commands do you use to query the GPSDO that it may be getting hung up on? Your software looks quite nice, and It would be great if your software could support our units like GPSCon does. Thanks in advance, Said The status window in your software shows the following: :SYSTEM:STATUS?

[time-nuts] Introduction of Z38XX
Gents, perhaps you have read that since a few days I am the owner of a Z3805 bought on eBAy from fluke.I. The other day a friend of mine visited me and brought his GPSCON with him to test it on my Z3805. As fluke.I had pointed out, the GPSCON would work with the Z3805 but it would not work really satisfying. The reason is that the Z3801 has a 6 channel receiver and the Z3816 has a 8 channel receiver, so GPSCON is simply not prepared to read more than 8 sat data sets from the Z3805's status screen (which has a 12 channel receiver). In addition, because the Z3805's status screen uses more lines for the display of the additional sat data sets GPSCON will miss the last three lines of the z3805's status screen. This in conjunction with some other things encouraged me me to write a z3805 tool of my own named Z38XX. Of course it will handle z3801s and z3816s as well. It is far from being complete but you can get a good impression of it by downloading it from the usual place http://www.ulrich-bangert.de/html/downloads.html Z38XX talks to the Z3801/5/16 with a exact 10 s time base which means the PPS TI delivered can be used for the computation of Allan deviation (and other measures) of the internal phase comparator with a Tau0 = 10 s (which is done internally in Z38XX similar as in Lady Heather). The sat's horizont line in the Azimuth / Elevation chart will look strange in the first hours after program start. Give it some days until it looks as attched or even better.
