I just noticed this on ebay
http://cgi.ebay.com/EFRATOM-TS-105A-ATOMIC-OSCILLATOR-TEST-SET_W0QQitemZ260203671354
I wonder if anyone knows anything about it? Looking at the pictures, the
asking price seems rather high. I don't think I want it but it aroused
my curiosity. Looks like there is an Efratom rubidium source in it and a
card cage that looks like 80's or early 90's technology.
I guess it automates the measurement process, but I assume it couldn't
measure better than the source that is in it.

Rex,
It's a wonderful piece of equipment. It contains a special low
noise rubidium with a deliberate synthesized frequency offset
of something like 10 Hz. This allows direct measurement of
the UUT using the heterodyne method with resolution down
in the -13's and -14's.
The computer inside collects data, does all the math, and displays
(in real-time) average frequency offset and Allan Deviation for
tau 0.1 to 100 seconds. It uses one of those 80's bright orange
plasma screens you don't see much anymore.
If you happen to have a better reference there is an ext ref input
that you can use and it switches from single to dual mixer mode.
I put some old photos of a TS-105A for you at:
http://www.leapsecond.com/museum/ts105a/
I've seen a couple over the years; none of them cheap.

Hi Everyone
I know that my Prologix device is functioning thanks to Ulrich's EZGPIB.
I however want to use this device under Linux. My Ubuntu box cannot find
/dev/ttyUSB0 but a Mepis Linux live CD can.
I have tried the following commands:
echo ++auto 0 CR > /dev/ttyUSB0
echo ++auto 1 CR > /dev/ttyUSB0
echo ++auto 0 \r > /dev/ttyUSB0
echo ++auto 1 \r > /dev/ttyUSB0
echo ++auto 0 \n > /dev/ttyUSB0
echo ++auto 1 \n > /dev/ttyUSB0
echo ++auto 0 \r\n > /dev/ttyUSB0
echo ++auto 1 \r\n > /dev/ttyUSB0
I have not been able to switch the led on from talk to listen.
Could someone give me a bash sample of the correct syntax to use?
Thanks in advance-Patrick

Hi Patrick --
Off the top of my head, I can't help with the syntax, but I wanted to
mention that sometimes under Linux a USB device will assume different
device names depending on how many times (and how recently) it's been
plugged and unplugged. So, it's possible the Prologix may answer on
ttyUSB1 or even ttyUSB2 after a few troubleshooting attempts.

I have excellent luck using a Prologix device on a couple of different
machines running ubuntu linux (7.04 and 7.10). I find it totally painless.
You might run usbview and see if the device is being recognized or look
at /var/log/messages while plugging in the device. Something like:
% sudo tail -f /var/log/messages
You should see the device get recognized and a message telling you what
device it is assigned to.
I use the ser2net daemon with the prologix device. This acts as a proxy
for accessing serial devices over the network. This way you can
telnet to the GPIB device from the local machine or over the network.
This makes it really convenient to access GPIB devices over the local
network.
As far as programming the GPIB devices, I use perl, it's a lot cleaner
than a bunch of crazy echo commands in a bash script. The Telnet module
in perl makes it easy to access the ser2net proxy to the GPIB device.
There are a lot of different ways to do it, but that's what works best
for me.

You don't have the daemon that automatically loads new USB
devices running. I forget its name, but it is easily found
by doing a google on linux USB.
Or, you can look in Synaptic and search on USB.
If I get a chance, I will look it up later on this evening.

Thanks to Chuck, Jeff, Christian and John!
I was trying to do a quick test with a live CD in bash but the general
message I have gotten is to fix the Ubuntu install. Indeed you were
right and I was wrong.
I tried this command (thanks Jeff)
sudo tail -f /var/log/messages
I found out that I had a conflict with brltty. I don't remember
installing a brail terminal!
It's funny it only had a conflict with the prologix device and not a
usb-serial adapter.
Anyhow I am trying to communicate with the device with PySerial now. I
am getting error messages back when I read but at least that's something.
Thanks again to all.

So sorry guys. I have been pulling my hair out for the last hour. One
more question please.
Abdul sent me over a PySerial script just before I bought this item.
In the script there was line line like this:
ser.write("plot;\r\n")
I have tried ser.write("++ver;\r\n') and many other commands and
carriage returns.
With ser.read(100) I get
'Unrecognized command\r\n'
So at least I have some communication. Could someone help me with the
syntax?

Patrick,
There is no semi-colon after Prologix adapter commands (those that start
with ++).
Try:
ser.write("++ver\r\n")

Thanks to Chuck, Jeff, Christian and John!
I was trying to do a quick test with a live CD in bash but the general
message I have gotten is to fix the Ubuntu install. Indeed you were
right and I was wrong.
I tried this command (thanks Jeff)
sudo tail -f /var/log/messages
I found out that I had a conflict with brltty. I don't remember
installing a brail terminal!
It's funny it only had a conflict with the prologix device and not a
usb-serial adapter.
Anyhow I am trying to communicate with the device with PySerial now. I
am getting error messages back when I read but at least that's something.
Thanks again to all.

by doing a google on linux USB.
Or, you can look in Synaptic and search on USB.
If I get a chance, I will look it up later on this evening.

Hi Everyone
I know that my Prologix device is functioning thanks to Ulrich's EZGPIB.
I however want to use this device under Linux. My Ubuntu box cannot find
/dev/ttyUSB0 but a Mepis Linux live CD can.
I have tried the following commands:
echo ++auto 0 CR > /dev/ttyUSB0
echo ++auto 1 CR > /dev/ttyUSB0
echo ++auto 0 \r > /dev/ttyUSB0
echo ++auto 1 \r > /dev/ttyUSB0
echo ++auto 0 \n > /dev/ttyUSB0
echo ++auto 1 \n > /dev/ttyUSB0
echo ++auto 0 \r\n > /dev/ttyUSB0
echo ++auto 1 \r\n > /dev/ttyUSB0
I have not been able to switch the led on from talk to listen.
Could someone give me a bash sample of the correct syntax to use?
Thanks in advance-Patrick

Patrick,
There is no semi-colon after Prologix adapter commands (those that start
with ++).
Try:
ser.write("++ver\r\n")

Abdul

So sorry guys. I have been pulling my hair out for the last hour. One
more question please.
Abdul sent me over a PySerial script just before I bought this item.
In the script there was line line like this:
ser.write("plot;\r\n")
I have tried ser.write("++ver;\r\n') and many other commands and
carriage returns.
With ser.read(100) I get
'Unrecognized command\r\n'
So at least I have some communication. Could someone help me with the
syntax?
Thanks in advance-Patrick
